I Summary of Operations

The landfill is being run efficiently and in accordance withproper sanitsty landfill procedures The Staff is placing refusein a manner to utilize all available volume within the limitsapproved by the State Department of Environmental Protection (DEP)Approved limits may be found in a report entitled Supplement toNorth End Disposal Area Closure Plan September 1981 Revised4882 (the Supplement)

From January through April 1984 refuse was being placed in theportion of the expansion area to the west of the leachate drainagainst the existing landfill embankment From May through theremainder of the report period refuse was being placed to the eastof the leachate drain on an area of previously placed refuse Bothof these areas are near capacity and it is expected that the opera-tions area will be moved to the main portion of the expansion areain the near future Prior to utilizing this area placing of fillto meet the required separation of waste and annual highgroundwater must be completed This subject is addressed in asubsequent section of this Report

City of Waterbury CO01956 NEDA Semi-Annual Report July 31 1984

An area to the east of the unpaved portion of the north-south access road and an adjoining area to the north of the east-west access road have been reserved for use as a wet weather operations area As the normal operations area has been quite high lately use of the wet weather area has not been necessary

I The elevations of the existing landfill to the south of the

east-west access road as of the June 8 1984 aerial topography are generally at the closure grade contours as shown on Figure 6 of the Supplement Specifically the top of the southwest edge of the landfill is at the closure contour the northeast corner is about 10 feet above and the central portion is some 5 feet below

I final contours Regarding horizontal extent of waste the southshyeast corner of the waste extends somewhat outside and to the southeast of the area shown in the Supplement

Daily cover is normally being placed so as to minimize litter There were several times during the report period lasting no more than a few days each when cover material placement was inadeshyquate These interruptions of cover material placement were caused by equipment breakdowns inadequate delivery of cover material from contract suppliers and use of equipment for other purposes such as installation of underdrains and grading and covering at the South End Disposal Area The slope of the working face is held at flatter than 2 horizontal to 1 vertical which maximizes compacshytion Litter throughout the site is minimal at this time although it was a problem after the severe snow and wind storm of March 29 1984 Toward the end of June complaints of bad odors were received from residents to the southeast of the landfill The odors were traced to two leachate breakouts These breakouts were treated with lime and covered There were two fires at the site during the period of this report The first was the fire bombing of the administration building in January These two fire bombs scorched the paint on the cement block wall but did no other damage (See Photo No 6 page A4) The second fire occurred when the 983 tracshytor loader broke a hydraulic line and caught fire The tractor was extensively damaged and has been removed from the site for repair

As in the past no rats or other vectors have been observed at the site

Maintenance of drainage systems by the Staff has been good This is evident by the fact that the flat top catch basin to the east of the weigh station has been kept clean and its outlet pipe clear This basin is a continuing maintenance problem in that it is the low point for a large drainage area The hay bales at the two upstream inlets to the leachate drain were replaced once during the report period but the drainage swales should be cleared of silt and debris

City of Waterbury 0001957 NEDA Semi-Annual Report July 31 1984

The perpetual problem of refuse dumping outside of the main gate had been reduced substantially by the placement of Dumping Prohibited signs Unfortunately the problem has returned over the past few weeks

Under letter dated January 5 1983 the DEP informed the City that as defined under the Federal Resource Conservation and Recoshyvery Act (RCRA) criteria NEDA is classified as an open dump Under RCRA criteria any landfill with a point discharge of leashychate is classed as an open dump The existing leachate drain initially constructed in 1958 is a point discharge of leachate into surface waters In the past NEDA has therefore been classhysified as an open dump and will continue to be so classified until the leachate drain is connected to the City sanitary sewer system

The DEP letter refers to Order from the Water Compliance Unit Specifically this is DEP Order no 3016 executed on March 4 1981 and requires the City to undertake certain measures to protect water quality The DEP letter also states that All actions (required by that Order) are on schedule The actions referred to are the completed extension of the leachate drain the installation of permanent groundwater monitoring wells and other activities identified in Order No 3016

Photographs illustrating the various operational items described above may be found in Appendix A

II Summary pf Improvement5

A Improvements by the Staff

Construction activity at NEDA during the last 6 month period consisted of installation of a portion of the underdrain system in the expansion area and the addition of several riser sections to the leachate drain manhole in the current operations area The underdrain consisted of about 500 feet of 6-inch pershyforated corrugated PVC drainage tubing and 2 laterals totaling 170 feet of 4-inch drainage tubing The pipes were bedded and backfilled with 1-inch screened gravel

B Other Improvements

A chain link fence topped with concertina barbed wire was installed around the administration building and the adjacent parking area

Electrical outlets for equipment block heaters were installed around the outside of the administration building Flood lights were also installed on the building

A program of Methane monitoring has been established and is being carried out by Staff personnel Several areas of the administration building are tested for methane every Monday morning In addition once a month methane levels are checked in catch basins and manholes in the storm drainage system and the leachate drain Records are being kept of all methane tests

Methane has not been detected in the administration building catch basins or the truck scale Methane levels in the leachate drain manholes have been recorded as high as 60 percent

Plans and specifications have been prepared for collection of the leachate presently discharging to Mark Lane and the disposal of such leachate in the municipal sewer system These plans are under review by the Waterbury City Engineer

Not necessarily an improvement but of significant concern and importance the severe storm of March 29 1984 tore the roofing and insulation off of the equipment bay of the administration building Only the steel decking remained of the roof Repairs were made by a roofing contractor during June 1984

Appendix A contains photographs illustrating the improveshyments described above

III Volume Uti1ization

The volume added to the site between the aerial topography flights of December 21 1983 and June 8 1984 a period of about 56 months was computed to be a total of about 78450 cubic yards (cy) or about 14000 cy of gross volume per month this volume represents refuse from both Wolcott and Waterbury plus cover material This represents a substantial decrease over the 19600 cy per months reported in the last semi-annual report dated January 30 1984

To estimate Wolcotts contribution during the period covered by this Report the Bureaus weight records for the months of December 1983 through June 1984 were reviewed These records show that for this 6 month period Wolcott contributed about 55 by weight of the total waste delivered

City of Waterbury NEDA Semi-Annual Report July 31 1984

1 It is proper to note that the above utilization rates are less $bull than the volume actually placed during the periods defined by the

dates of the aerial mapping This situation is due to the fact that the deeper layers of waste are continually being compacted by ( the weight of the recently placed waste and cover material The difference in volume between actual and that computed by topography

9 cannot be estimated with accuracy due to the variables inherent in | the amount of initial compaction when waste is deposited the 4 decomposition of the waste itself and the amount of cover material

used

J Past experience at the landfill shows that when waste is placed on virgin ground utilization rates increase with computed densities

f in the neighborhood of 700 pounds per cubic yard When the waste | is placed on deep layers of previous wastes the utilization rate

decreases and computed densities are 1000 pounds per cubic yard or mor e

IV Volume Remaining ( 1 The Supplement which has been approved by DEP defines the final

contours of the ultimate landfill which includes the expansion area and the Wolcott land

1 Based on the final contours noted above total unused volume at the landfill available for the deposition of waste (and daily cover) is about 908000 cy as of June 8 1984 not including the 2

feet of final cover

V Recommendations for Operations

It is recommended that operations continue in the present operations area and the area to the west of the leachate drain As these areas are high and not affected by wet weather a separate wet weather area is not required Additional volume is available along the east side of the gravel portion of the North-South access road and to the north of the East-West access road These areas will be needed for wet weather operations when operations shift to the east side of the expansion area

NEDA Semi-Annual Report July 31 1984

With regard to maintenance the item of prime importance is the proper operation of the two inlets at the upstream end of the leachate drain and the storm drains throughout the site The hay bales which protect the leachate drain inlet should be replaced periodically to maintain the flow and protect the water quality in the adjacent monitoring wells All storm drain receivers should be kept clear to promote proper surface drainage and thus minimize

leachate production

VI Expansion Area

During this report period underdrains were installed in a portion of the expansion area east of the leachate drain Temporary groundwater monitoring wells were also installed and read twice weekly from the end of March through May Field surveys were also conducted to determine the locations and elevations of ledge out crops The water levels and ledge elevations were plotted and base fill levels determined for lift No 1 See Figure 1 page 10 Five feet of fill are shown between high groundwater or ledge and the base of lift No 1 The quantity of fill required was calculated to be about 10000 cubic yards

Approval of the fill contours for the base of lift No 1 must be obtained from DEP prior to placing waste in this portion of the expansion area

VII Water Quality Monitoring Program

lpound accordance with the Supplement the water quality monitoring program has continued at NEDA although with DEP concurrence the sampling points have changed The sampling points known as the inlet and the weir were deleted from the monitoring program after the April 1982 samples Sampling points known as Wells A B C and D are groundwater samples Surface water samples are taken froiu the pond northwest of the NEDA and the unnamed brook in Wolcott A sample of the leachate is taken from the headwall of the leachate drain These sampling points are shown on Figure 2 page 11 For the purpose of this Report all samples taken were tested for indicator and specific parameters as detailed in the Supplement Laboratory analyses were performed in part by the Citys Water Pollution Control Facility Laboratory and in part by the Ellis A Tarlton Laboratory in Danbury Connecticut Test results are shown in Appendix B

VIII Review of Test Results

A GroundwaterSurface Water

The results of the water quality tests for groundwater and surface water are detailed in Tables 1 and 2 pages 12 and 13 respectively The standards used for judging the quality of groundwatersurface water are the drinking water standards of the 1980 State Public Health Code and the various Public Acts of Congress defined by the US Environmental Protection Agency

Test results of the groundwater monitoring wells Table 1 indicates that in general the current test results are at or below the historical average of results since monitoring began except for solids which show an increase

Table 2 indicates a similar pattern in the test results for the surface water samples Essentially all parameters are at or below historic averages except for a rise in manganese level in the pond

B Leachate

The test results on the leachate sample taken at the leachate drain headwall are shown on Table 3 page 14 The standard used to compare NEDA leachate to other leachate is a summary of the broad range of values found in the American Society of Civil Engineers Manual of Protection No 39 - Sanitary Landfill 1976 Groundwater by Freeze and Cherry 1979 and Solid Wastes by Tchobanoglous Theisen and Eliassen 1977 It appears that the leachate produced at NEDA is within these ranges and docs not appear to have any unusual characteristics The results are comparable to the historical average dating back to 1977 The results do show increases in concentration of several of the parameters especially solids This may be due to the installation of the underdrain and the dry weather prior to sampling

IX Future Water Quality Testing

I

I11

Mercury silver barium and selenium have been deleted from L further testing programs at the four wells the brook in Wolcott and the pond west of NEDA Test results for mercury have been

I negative since the initial testing therefore it must be assumed that the initial tests were in error and mercury is not present at the site No selenium hexavalent chromium or silver has been detected in any samples since testing began and barium has only been detected in traces well below drinking water standards Barium mercury selenium and silver have also been deleted from the testing program at the leachate headwall as no significant quantities have been found in the leachate

X Flow Mopitoripg Program

The purpose of the flow monitoring program is to gather suffishycient data to properly size the future pipe which will ultimately connect the leachate drain to the City sanitary sewer system

The location of the leachate drain flow monitor rain gauge and drainage area tributary to the leachate drain are shown on Figure 3 page 15

The equipment is inspected weekly following a standard routine to ensure proper operations The flow monitor was taken out of service for repairs from February 11 1983 to March 29 1983 and from April 6 1984 to April 19 1984 Due to freezing temperashytures the rain gauge was taken out of service in December 1983 and was reinstalled on February 28 1984 Otherwise both the flow monitor and rain gauge have recorded data since July 1982

Historically the dry weather flow at the leachate drain headshywall shows the depth of flow in the 18-inch diameter pipe to be 12 inch Recent measurements of the dry weather flow have been about 25 - 30 gallons per minute

It is recommended that the present program of data collection be continued in its present form Evaluation of the effect of refuse placement over the extension of the leachate drain into the expansion area will be made as operations continue into that area

XI Recommendations

As previously discussed the final contours of lift No 1 fill to be placed in the expansion area east of the leachate drain must be approved by DEP Placement of wastes to the east of the leachate drain should be delayed until DEP approval is obtained

With regard to maintenance it is recommended the Staff keep the storm drainage and leachate drain system clear and operational This includes the clearing of pipe inlets and the periodic replacement of the hay bales which protect the upstream end of the leachate drain It is also recommended that the drainage swale be kept clear of silt and debris to maintain proper drainage and reduce the possibility of contamination of surface waters in Wolcott

Methane monitoring of the administration building and the leachate drain manholes should be continued

The drainage swale to the north of the paved access road has been kept clear of litter however it is suggested the swale be deepened so the flow will not escape over the pavement and erode the slope to the south of the access road

As stated in previous reports the westerly slopes have been graded and cover placed so that they now present a very good appearance It is suggested that these slopes be learned and seeded in the fall The portions of the southerly slope north of the paved access road have a good growth of vegetation and present a good appearance

We trust the above Report is satisfactory to you and would be pleased to meet with you to discuss its contents Hay we compliment your Staff at NEDA for the job they have done in regard to daily operations and maintenance

Very truly yours

An area to the east of the unpaved portion of the north-south access road and an adjoining area to the north of the east-west access road have been reserved for use as a wet weather operations area As the normal operations area has been quite high lately use of the wet weather area has not been necessary

I The elevations of the existing landfill to the south of the

east-west access road as of the June 8 1984 aerial topography are generally at the closure grade contours as shown on Figure 6 of the Supplement Specifically the top of the southwest edge of the landfill is at the closure contour the northeast corner is about 10 feet above and the central portion is some 5 feet below

I final contours Regarding horizontal extent of waste the southshyeast corner of the waste extends somewhat outside and to the southeast of the area shown in the Supplement

Daily cover is normally being placed so as to minimize litter There were several times during the report period lasting no more than a few days each when cover material placement was inadeshyquate These interruptions of cover material placement were caused by equipment breakdowns inadequate delivery of cover material from contract suppliers and use of equipment for other purposes such as installation of underdrains and grading and covering at the South End Disposal Area The slope of the working face is held at flatter than 2 horizontal to 1 vertical which maximizes compacshytion Litter throughout the site is minimal at this time although it was a problem after the severe snow and wind storm of March 29 1984 Toward the end of June complaints of bad odors were received from residents to the southeast of the landfill The odors were traced to two leachate breakouts These breakouts were treated with lime and covered There were two fires at the site during the period of this report The first was the fire bombing of the administration building in January These two fire bombs scorched the paint on the cement block wall but did no other damage (See Photo No 6 page A4) The second fire occurred when the 983 tracshytor loader broke a hydraulic line and caught fire The tractor was extensively damaged and has been removed from the site for repair

As in the past no rats or other vectors have been observed at the site

Maintenance of drainage systems by the Staff has been good This is evident by the fact that the flat top catch basin to the east of the weigh station has been kept clean and its outlet pipe clear This basin is a continuing maintenance problem in that it is the low point for a large drainage area The hay bales at the two upstream inlets to the leachate drain were replaced once during the report period but the drainage swales should be cleared of silt and debris

City of Waterbury 0001957 NEDA Semi-Annual Report July 31 1984

The perpetual problem of refuse dumping outside of the main gate had been reduced substantially by the placement of Dumping Prohibited signs Unfortunately the problem has returned over the past few weeks

Under letter dated January 5 1983 the DEP informed the City that as defined under the Federal Resource Conservation and Recoshyvery Act (RCRA) criteria NEDA is classified as an open dump Under RCRA criteria any landfill with a point discharge of leashychate is classed as an open dump The existing leachate drain initially constructed in 1958 is a point discharge of leachate into surface waters In the past NEDA has therefore been classhysified as an open dump and will continue to be so classified until the leachate drain is connected to the City sanitary sewer system

The DEP letter refers to Order from the Water Compliance Unit Specifically this is DEP Order no 3016 executed on March 4 1981 and requires the City to undertake certain measures to protect water quality The DEP letter also states that All actions (required by that Order) are on schedule The actions referred to are the completed extension of the leachate drain the installation of permanent groundwater monitoring wells and other activities identified in Order No 3016

Photographs illustrating the various operational items described above may be found in Appendix A

II Summary pf Improvement5

A Improvements by the Staff

Construction activity at NEDA during the last 6 month period consisted of installation of a portion of the underdrain system in the expansion area and the addition of several riser sections to the leachate drain manhole in the current operations area The underdrain consisted of about 500 feet of 6-inch pershyforated corrugated PVC drainage tubing and 2 laterals totaling 170 feet of 4-inch drainage tubing The pipes were bedded and backfilled with 1-inch screened gravel

B Other Improvements

A chain link fence topped with concertina barbed wire was installed around the administration building and the adjacent parking area

Electrical outlets for equipment block heaters were installed around the outside of the administration building Flood lights were also installed on the building

A program of Methane monitoring has been established and is being carried out by Staff personnel Several areas of the administration building are tested for methane every Monday morning In addition once a month methane levels are checked in catch basins and manholes in the storm drainage system and the leachate drain Records are being kept of all methane tests

Methane has not been detected in the administration building catch basins or the truck scale Methane levels in the leachate drain manholes have been recorded as high as 60 percent

Plans and specifications have been prepared for collection of the leachate presently discharging to Mark Lane and the disposal of such leachate in the municipal sewer system These plans are under review by the Waterbury City Engineer

Not necessarily an improvement but of significant concern and importance the severe storm of March 29 1984 tore the roofing and insulation off of the equipment bay of the administration building Only the steel decking remained of the roof Repairs were made by a roofing contractor during June 1984

Appendix A contains photographs illustrating the improveshyments described above

III Volume Uti1ization

The volume added to the site between the aerial topography flights of December 21 1983 and June 8 1984 a period of about 56 months was computed to be a total of about 78450 cubic yards (cy) or about 14000 cy of gross volume per month this volume represents refuse from both Wolcott and Waterbury plus cover material This represents a substantial decrease over the 19600 cy per months reported in the last semi-annual report dated January 30 1984

To estimate Wolcotts contribution during the period covered by this Report the Bureaus weight records for the months of December 1983 through June 1984 were reviewed These records show that for this 6 month period Wolcott contributed about 55 by weight of the total waste delivered

ROALD HAESTAD NC OOO1359

City of Waterbury NEDA Semi-Annual Report July 31 1984

1 It is proper to note that the above utilization rates are less $bull than the volume actually placed during the periods defined by the

dates of the aerial mapping This situation is due to the fact that the deeper layers of waste are continually being compacted by ( the weight of the recently placed waste and cover material The difference in volume between actual and that computed by topography

9 cannot be estimated with accuracy due to the variables inherent in | the amount of initial compaction when waste is deposited the 4 decomposition of the waste itself and the amount of cover material

used

J Past experience at the landfill shows that when waste is placed on virgin ground utilization rates increase with computed densities

f in the neighborhood of 700 pounds per cubic yard When the waste | is placed on deep layers of previous wastes the utilization rate

decreases and computed densities are 1000 pounds per cubic yard or mor e

IV Volume Remaining ( 1 The Supplement which has been approved by DEP defines the final

contours of the ultimate landfill which includes the expansion area and the Wolcott land

1 Based on the final contours noted above total unused volume at the landfill available for the deposition of waste (and daily cover) is about 908000 cy as of June 8 1984 not including the 2

feet of final cover

V Recommendations for Operations

It is recommended that operations continue in the present operations area and the area to the west of the leachate drain As these areas are high and not affected by wet weather a separate wet weather area is not required Additional volume is available along the east side of the gravel portion of the North-South access road and to the north of the East-West access road These areas will be needed for wet weather operations when operations shift to the east side of the expansion area

NEDA Semi-Annual Report July 31 1984

With regard to maintenance the item of prime importance is the proper operation of the two inlets at the upstream end of the leachate drain and the storm drains throughout the site The hay bales which protect the leachate drain inlet should be replaced periodically to maintain the flow and protect the water quality in the adjacent monitoring wells All storm drain receivers should be kept clear to promote proper surface drainage and thus minimize

leachate production

VI Expansion Area

During this report period underdrains were installed in a portion of the expansion area east of the leachate drain Temporary groundwater monitoring wells were also installed and read twice weekly from the end of March through May Field surveys were also conducted to determine the locations and elevations of ledge out crops The water levels and ledge elevations were plotted and base fill levels determined for lift No 1 See Figure 1 page 10 Five feet of fill are shown between high groundwater or ledge and the base of lift No 1 The quantity of fill required was calculated to be about 10000 cubic yards

Approval of the fill contours for the base of lift No 1 must be obtained from DEP prior to placing waste in this portion of the expansion area

VII Water Quality Monitoring Program

lpound accordance with the Supplement the water quality monitoring program has continued at NEDA although with DEP concurrence the sampling points have changed The sampling points known as the inlet and the weir were deleted from the monitoring program after the April 1982 samples Sampling points known as Wells A B C and D are groundwater samples Surface water samples are taken froiu the pond northwest of the NEDA and the unnamed brook in Wolcott A sample of the leachate is taken from the headwall of the leachate drain These sampling points are shown on Figure 2 page 11 For the purpose of this Report all samples taken were tested for indicator and specific parameters as detailed in the Supplement Laboratory analyses were performed in part by the Citys Water Pollution Control Facility Laboratory and in part by the Ellis A Tarlton Laboratory in Danbury Connecticut Test results are shown in Appendix B

VIII Review of Test Results

A GroundwaterSurface Water

The results of the water quality tests for groundwater and surface water are detailed in Tables 1 and 2 pages 12 and 13 respectively The standards used for judging the quality of groundwatersurface water are the drinking water standards of the 1980 State Public Health Code and the various Public Acts of Congress defined by the US Environmental Protection Agency

Test results of the groundwater monitoring wells Table 1 indicates that in general the current test results are at or below the historical average of results since monitoring began except for solids which show an increase

Table 2 indicates a similar pattern in the test results for the surface water samples Essentially all parameters are at or below historic averages except for a rise in manganese level in the pond

B Leachate

The test results on the leachate sample taken at the leachate drain headwall are shown on Table 3 page 14 The standard used to compare NEDA leachate to other leachate is a summary of the broad range of values found in the American Society of Civil Engineers Manual of Protection No 39 - Sanitary Landfill 1976 Groundwater by Freeze and Cherry 1979 and Solid Wastes by Tchobanoglous Theisen and Eliassen 1977 It appears that the leachate produced at NEDA is within these ranges and docs not appear to have any unusual characteristics The results are comparable to the historical average dating back to 1977 The results do show increases in concentration of several of the parameters especially solids This may be due to the installation of the underdrain and the dry weather prior to sampling

IX Future Water Quality Testing

I

I11

Mercury silver barium and selenium have been deleted from L further testing programs at the four wells the brook in Wolcott and the pond west of NEDA Test results for mercury have been

I negative since the initial testing therefore it must be assumed that the initial tests were in error and mercury is not present at the site No selenium hexavalent chromium or silver has been detected in any samples since testing began and barium has only been detected in traces well below drinking water standards Barium mercury selenium and silver have also been deleted from the testing program at the leachate headwall as no significant quantities have been found in the leachate

X Flow Mopitoripg Program

The purpose of the flow monitoring program is to gather suffishycient data to properly size the future pipe which will ultimately connect the leachate drain to the City sanitary sewer system

The location of the leachate drain flow monitor rain gauge and drainage area tributary to the leachate drain are shown on Figure 3 page 15

The equipment is inspected weekly following a standard routine to ensure proper operations The flow monitor was taken out of service for repairs from February 11 1983 to March 29 1983 and from April 6 1984 to April 19 1984 Due to freezing temperashytures the rain gauge was taken out of service in December 1983 and was reinstalled on February 28 1984 Otherwise both the flow monitor and rain gauge have recorded data since July 1982

Historically the dry weather flow at the leachate drain headshywall shows the depth of flow in the 18-inch diameter pipe to be 12 inch Recent measurements of the dry weather flow have been about 25 - 30 gallons per minute

It is recommended that the present program of data collection be continued in its present form Evaluation of the effect of refuse placement over the extension of the leachate drain into the expansion area will be made as operations continue into that area

XI Recommendations

As previously discussed the final contours of lift No 1 fill to be placed in the expansion area east of the leachate drain must be approved by DEP Placement of wastes to the east of the leachate drain should be delayed until DEP approval is obtained

With regard to maintenance it is recommended the Staff keep the storm drainage and leachate drain system clear and operational This includes the clearing of pipe inlets and the periodic replacement of the hay bales which protect the upstream end of the leachate drain It is also recommended that the drainage swale be kept clear of silt and debris to maintain proper drainage and reduce the possibility of contamination of surface waters in Wolcott

Methane monitoring of the administration building and the leachate drain manholes should be continued

The drainage swale to the north of the paved access road has been kept clear of litter however it is suggested the swale be deepened so the flow will not escape over the pavement and erode the slope to the south of the access road

As stated in previous reports the westerly slopes have been graded and cover placed so that they now present a very good appearance It is suggested that these slopes be learned and seeded in the fall The portions of the southerly slope north of the paved access road have a good growth of vegetation and present a good appearance

We trust the above Report is satisfactory to you and would be pleased to meet with you to discuss its contents Hay we compliment your Staff at NEDA for the job they have done in regard to daily operations and maintenance

Very truly yours

The perpetual problem of refuse dumping outside of the main gate had been reduced substantially by the placement of Dumping Prohibited signs Unfortunately the problem has returned over the past few weeks

Under letter dated January 5 1983 the DEP informed the City that as defined under the Federal Resource Conservation and Recoshyvery Act (RCRA) criteria NEDA is classified as an open dump Under RCRA criteria any landfill with a point discharge of leashychate is classed as an open dump The existing leachate drain initially constructed in 1958 is a point discharge of leachate into surface waters In the past NEDA has therefore been classhysified as an open dump and will continue to be so classified until the leachate drain is connected to the City sanitary sewer system

The DEP letter refers to Order from the Water Compliance Unit Specifically this is DEP Order no 3016 executed on March 4 1981 and requires the City to undertake certain measures to protect water quality The DEP letter also states that All actions (required by that Order) are on schedule The actions referred to are the completed extension of the leachate drain the installation of permanent groundwater monitoring wells and other activities identified in Order No 3016

II Summary pf Improvement5

A Improvements by the Staff

Construction activity at NEDA during the last 6 month period consisted of installation of a portion of the underdrain system in the expansion area and the addition of several riser sections to the leachate drain manhole in the current operations area The underdrain consisted of about 500 feet of 6-inch pershyforated corrugated PVC drainage tubing and 2 laterals totaling 170 feet of 4-inch drainage tubing The pipes were bedded and backfilled with 1-inch screened gravel

B Other Improvements

A chain link fence topped with concertina barbed wire was installed around the administration building and the adjacent parking area

Electrical outlets for equipment block heaters were installed around the outside of the administration building Flood lights were also installed on the building

A program of Methane monitoring has been established and is being carried out by Staff personnel Several areas of the administration building are tested for methane every Monday morning In addition once a month methane levels are checked in catch basins and manholes in the storm drainage system and the leachate drain Records are being kept of all methane tests

Methane has not been detected in the administration building catch basins or the truck scale Methane levels in the leachate drain manholes have been recorded as high as 60 percent

Plans and specifications have been prepared for collection of the leachate presently discharging to Mark Lane and the disposal of such leachate in the municipal sewer system These plans are under review by the Waterbury City Engineer

Not necessarily an improvement but of significant concern and importance the severe storm of March 29 1984 tore the roofing and insulation off of the equipment bay of the administration building Only the steel decking remained of the roof Repairs were made by a roofing contractor during June 1984

Appendix A contains photographs illustrating the improveshyments described above

III Volume Uti1ization

The volume added to the site between the aerial topography flights of December 21 1983 and June 8 1984 a period of about 56 months was computed to be a total of about 78450 cubic yards (cy) or about 14000 cy of gross volume per month this volume represents refuse from both Wolcott and Waterbury plus cover material This represents a substantial decrease over the 19600 cy per months reported in the last semi-annual report dated January 30 1984

To estimate Wolcotts contribution during the period covered by this Report the Bureaus weight records for the months of December 1983 through June 1984 were reviewed These records show that for this 6 month period Wolcott contributed about 55 by weight of the total waste delivered

1 It is proper to note that the above utilization rates are less $bull than the volume actually placed during the periods defined by the

dates of the aerial mapping This situation is due to the fact that the deeper layers of waste are continually being compacted by ( the weight of the recently placed waste and cover material The difference in volume between actual and that computed by topography

9 cannot be estimated with accuracy due to the variables inherent in | the amount of initial compaction when waste is deposited the 4 decomposition of the waste itself and the amount of cover material

used

J Past experience at the landfill shows that when waste is placed on virgin ground utilization rates increase with computed densities

f in the neighborhood of 700 pounds per cubic yard When the waste | is placed on deep layers of previous wastes the utilization rate

decreases and computed densities are 1000 pounds per cubic yard or mor e

IV Volume Remaining ( 1 The Supplement which has been approved by DEP defines the final

contours of the ultimate landfill which includes the expansion area and the Wolcott land

1 Based on the final contours noted above total unused volume at the landfill available for the deposition of waste (and daily cover) is about 908000 cy as of June 8 1984 not including the 2

feet of final cover

V Recommendations for Operations

It is recommended that operations continue in the present operations area and the area to the west of the leachate drain As these areas are high and not affected by wet weather a separate wet weather area is not required Additional volume is available along the east side of the gravel portion of the North-South access road and to the north of the East-West access road These areas will be needed for wet weather operations when operations shift to the east side of the expansion area

With regard to maintenance the item of prime importance is the proper operation of the two inlets at the upstream end of the leachate drain and the storm drains throughout the site The hay bales which protect the leachate drain inlet should be replaced periodically to maintain the flow and protect the water quality in the adjacent monitoring wells All storm drain receivers should be kept clear to promote proper surface drainage and thus minimize

leachate production

VI Expansion Area

During this report period underdrains were installed in a portion of the expansion area east of the leachate drain Temporary groundwater monitoring wells were also installed and read twice weekly from the end of March through May Field surveys were also conducted to determine the locations and elevations of ledge out crops The water levels and ledge elevations were plotted and base fill levels determined for lift No 1 See Figure 1 page 10 Five feet of fill are shown between high groundwater or ledge and the base of lift No 1 The quantity of fill required was calculated to be about 10000 cubic yards

Approval of the fill contours for the base of lift No 1 must be obtained from DEP prior to placing waste in this portion of the expansion area

VII Water Quality Monitoring Program

lpound accordance with the Supplement the water quality monitoring program has continued at NEDA although with DEP concurrence the sampling points have changed The sampling points known as the inlet and the weir were deleted from the monitoring program after the April 1982 samples Sampling points known as Wells A B C and D are groundwater samples Surface water samples are taken froiu the pond northwest of the NEDA and the unnamed brook in Wolcott A sample of the leachate is taken from the headwall of the leachate drain These sampling points are shown on Figure 2 page 11 For the purpose of this Report all samples taken were tested for indicator and specific parameters as detailed in the Supplement Laboratory analyses were performed in part by the Citys Water Pollution Control Facility Laboratory and in part by the Ellis A Tarlton Laboratory in Danbury Connecticut Test results are shown in Appendix B

VIII Review of Test Results

A GroundwaterSurface Water

The results of the water quality tests for groundwater and surface water are detailed in Tables 1 and 2 pages 12 and 13 respectively The standards used for judging the quality of groundwatersurface water are the drinking water standards of the 1980 State Public Health Code and the various Public Acts of Congress defined by the US Environmental Protection Agency

Test results of the groundwater monitoring wells Table 1 indicates that in general the current test results are at or below the historical average of results since monitoring began except for solids which show an increase

Table 2 indicates a similar pattern in the test results for the surface water samples Essentially all parameters are at or below historic averages except for a rise in manganese level in the pond

B Leachate

The test results on the leachate sample taken at the leachate drain headwall are shown on Table 3 page 14 The standard used to compare NEDA leachate to other leachate is a summary of the broad range of values found in the American Society of Civil Engineers Manual of Protection No 39 - Sanitary Landfill 1976 Groundwater by Freeze and Cherry 1979 and Solid Wastes by Tchobanoglous Theisen and Eliassen 1977 It appears that the leachate produced at NEDA is within these ranges and docs not appear to have any unusual characteristics The results are comparable to the historical average dating back to 1977 The results do show increases in concentration of several of the parameters especially solids This may be due to the installation of the underdrain and the dry weather prior to sampling

IX Future Water Quality Testing

I

I11

Mercury silver barium and selenium have been deleted from L further testing programs at the four wells the brook in Wolcott and the pond west of NEDA Test results for mercury have been

I negative since the initial testing therefore it must be assumed that the initial tests were in error and mercury is not present at the site No selenium hexavalent chromium or silver has been detected in any samples since testing began and barium has only been detected in traces well below drinking water standards Barium mercury selenium and silver have also been deleted from the testing program at the leachate headwall as no significant quantities have been found in the leachate

X Flow Mopitoripg Program

The purpose of the flow monitoring program is to gather suffishycient data to properly size the future pipe which will ultimately connect the leachate drain to the City sanitary sewer system

The location of the leachate drain flow monitor rain gauge and drainage area tributary to the leachate drain are shown on Figure 3 page 15

The equipment is inspected weekly following a standard routine to ensure proper operations The flow monitor was taken out of service for repairs from February 11 1983 to March 29 1983 and from April 6 1984 to April 19 1984 Due to freezing temperashytures the rain gauge was taken out of service in December 1983 and was reinstalled on February 28 1984 Otherwise both the flow monitor and rain gauge have recorded data since July 1982

Historically the dry weather flow at the leachate drain headshywall shows the depth of flow in the 18-inch diameter pipe to be 12 inch Recent measurements of the dry weather flow have been about 25 - 30 gallons per minute

It is recommended that the present program of data collection be continued in its present form Evaluation of the effect of refuse placement over the extension of the leachate drain into the expansion area will be made as operations continue into that area

XI Recommendations

As previously discussed the final contours of lift No 1 fill to be placed in the expansion area east of the leachate drain must be approved by DEP Placement of wastes to the east of the leachate drain should be delayed until DEP approval is obtained

With regard to maintenance it is recommended the Staff keep the storm drainage and leachate drain system clear and operational This includes the clearing of pipe inlets and the periodic replacement of the hay bales which protect the upstream end of the leachate drain It is also recommended that the drainage swale be kept clear of silt and debris to maintain proper drainage and reduce the possibility of contamination of surface waters in Wolcott

Methane monitoring of the administration building and the leachate drain manholes should be continued

The drainage swale to the north of the paved access road has been kept clear of litter however it is suggested the swale be deepened so the flow will not escape over the pavement and erode the slope to the south of the access road

As stated in previous reports the westerly slopes have been graded and cover placed so that they now present a very good appearance It is suggested that these slopes be learned and seeded in the fall The portions of the southerly slope north of the paved access road have a good growth of vegetation and present a good appearance

We trust the above Report is satisfactory to you and would be pleased to meet with you to discuss its contents Hay we compliment your Staff at NEDA for the job they have done in regard to daily operations and maintenance

Very truly yours

The test results on the leachate sample taken at the leachate drain headwall are shown on Table 3 page 14 The standard used to compare NEDA leachate to other leachate is a summary of the broad range of values found in the American Society of Civil Engineers Manual of Protection No 39 - Sanitary Landfill 1976 Groundwater by Freeze and Cherry 1979 and Solid Wastes by Tchobanoglous Theisen and Eliassen 1977 It appears that the leachate produced at NEDA is within these ranges and docs not appear to have any unusual characteristics The results are comparable to the historical average dating back to 1977 The results do show increases in concentration of several of the parameters especially solids This may be due to the installation of the underdrain and the dry weather prior to sampling

Mercury silver barium and selenium have been deleted from L further testing programs at the four wells the brook in Wolcott and the pond west of NEDA Test results for mercury have been

I negative since the initial testing therefore it must be assumed that the initial tests were in error and mercury is not present at the site No selenium hexavalent chromium or silver has been detected in any samples since testing began and barium has only been detected in traces well below drinking water standards Barium mercury selenium and silver have also been deleted from the testing program at the leachate headwall as no significant quantities have been found in the leachate

X Flow Mopitoripg Program

The purpose of the flow monitoring program is to gather suffishycient data to properly size the future pipe which will ultimately connect the leachate drain to the City sanitary sewer system

The location of the leachate drain flow monitor rain gauge and drainage area tributary to the leachate drain are shown on Figure 3 page 15

The equipment is inspected weekly following a standard routine to ensure proper operations The flow monitor was taken out of service for repairs from February 11 1983 to March 29 1983 and from April 6 1984 to April 19 1984 Due to freezing temperashytures the rain gauge was taken out of service in December 1983 and was reinstalled on February 28 1984 Otherwise both the flow monitor and rain gauge have recorded data since July 1982

Historically the dry weather flow at the leachate drain headshywall shows the depth of flow in the 18-inch diameter pipe to be 12 inch Recent measurements of the dry weather flow have been about 25 - 30 gallons per minute

It is recommended that the present program of data collection be continued in its present form Evaluation of the effect of refuse placement over the extension of the leachate drain into the expansion area will be made as operations continue into that area

XI Recommendations

As previously discussed the final contours of lift No 1 fill to be placed in the expansion area east of the leachate drain must be approved by DEP Placement of wastes to the east of the leachate drain should be delayed until DEP approval is obtained

With regard to maintenance it is recommended the Staff keep the storm drainage and leachate drain system clear and operational This includes the clearing of pipe inlets and the periodic replacement of the hay bales which protect the upstream end of the leachate drain It is also recommended that the drainage swale be kept clear of silt and debris to maintain proper drainage and reduce the possibility of contamination of surface waters in Wolcott

Methane monitoring of the administration building and the leachate drain manholes should be continued

The drainage swale to the north of the paved access road has been kept clear of litter however it is suggested the swale be deepened so the flow will not escape over the pavement and erode the slope to the south of the access road

As stated in previous reports the westerly slopes have been graded and cover placed so that they now present a very good appearance It is suggested that these slopes be learned and seeded in the fall The portions of the southerly slope north of the paved access road have a good growth of vegetation and present a good appearance

We trust the above Report is satisfactory to you and would be pleased to meet with you to discuss its contents Hay we compliment your Staff at NEDA for the job they have done in regard to daily operations and maintenance

City of Waterbury NEDA Semi-Annual Report July 31 1984

1 It is proper to note that the above utilization rates are less $bull than the volume actually placed during the periods defined by the

dates of the aerial mapping This situation is due to the fact that the deeper layers of waste are continually being compacted by ( the weight of the recently placed waste and cover material The difference in volume between actual and that computed by topography

9 cannot be estimated with accuracy due to the variables inherent in | the amount of initial compaction when waste is deposited the 4 decomposition of the waste itself and the amount of cover material

used

J Past experience at the landfill shows that when waste is placed on virgin ground utilization rates increase with computed densities

f in the neighborhood of 700 pounds per cubic yard When the waste | is placed on deep layers of previous wastes the utilization rate

decreases and computed densities are 1000 pounds per cubic yard or mor e

IV Volume Remaining ( 1 The Supplement which has been approved by DEP defines the final

contours of the ultimate landfill which includes the expansion area and the Wolcott land

1 Based on the final contours noted above total unused volume at the landfill available for the deposition of waste (and daily cover) is about 908000 cy as of June 8 1984 not including the 2

feet of final cover

V Recommendations for Operations

It is recommended that operations continue in the present operations area and the area to the west of the leachate drain As these areas are high and not affected by wet weather a separate wet weather area is not required Additional volume is available along the east side of the gravel portion of the North-South access road and to the north of the East-West access road These areas will be needed for wet weather operations when operations shift to the east side of the expansion area

NEDA Semi-Annual Report July 31 1984

With regard to maintenance the item of prime importance is the proper operation of the two inlets at the upstream end of the leachate drain and the storm drains throughout the site The hay bales which protect the leachate drain inlet should be replaced periodically to maintain the flow and protect the water quality in the adjacent monitoring wells All storm drain receivers should be kept clear to promote proper surface drainage and thus minimize

leachate production

VI Expansion Area

During this report period underdrains were installed in a portion of the expansion area east of the leachate drain Temporary groundwater monitoring wells were also installed and read twice weekly from the end of March through May Field surveys were also conducted to determine the locations and elevations of ledge out crops The water levels and ledge elevations were plotted and base fill levels determined for lift No 1 See Figure 1 page 10 Five feet of fill are shown between high groundwater or ledge and the base of lift No 1 The quantity of fill required was calculated to be about 10000 cubic yards

Approval of the fill contours for the base of lift No 1 must be obtained from DEP prior to placing waste in this portion of the expansion area

VII Water Quality Monitoring Program

lpound accordance with the Supplement the water quality monitoring program has continued at NEDA although with DEP concurrence the sampling points have changed The sampling points known as the inlet and the weir were deleted from the monitoring program after the April 1982 samples Sampling points known as Wells A B C and D are groundwater samples Surface water samples are taken froiu the pond northwest of the NEDA and the unnamed brook in Wolcott A sample of the leachate is taken from the headwall of the leachate drain These sampling points are shown on Figure 2 page 11 For the purpose of this Report all samples taken were tested for indicator and specific parameters as detailed in the Supplement Laboratory analyses were performed in part by the Citys Water Pollution Control Facility Laboratory and in part by the Ellis A Tarlton Laboratory in Danbury Connecticut Test results are shown in Appendix B

VIII Review of Test Results

A GroundwaterSurface Water

The results of the water quality tests for groundwater and surface water are detailed in Tables 1 and 2 pages 12 and 13 respectively The standards used for judging the quality of groundwatersurface water are the drinking water standards of the 1980 State Public Health Code and the various Public Acts of Congress defined by the US Environmental Protection Agency

Test results of the groundwater monitoring wells Table 1 indicates that in general the current test results are at or below the historical average of results since monitoring began except for solids which show an increase

Table 2 indicates a similar pattern in the test results for the surface water samples Essentially all parameters are at or below historic averages except for a rise in manganese level in the pond

B Leachate

The test results on the leachate sample taken at the leachate drain headwall are shown on Table 3 page 14 The standard used to compare NEDA leachate to other leachate is a summary of the broad range of values found in the American Society of Civil Engineers Manual of Protection No 39 - Sanitary Landfill 1976 Groundwater by Freeze and Cherry 1979 and Solid Wastes by Tchobanoglous Theisen and Eliassen 1977 It appears that the leachate produced at NEDA is within these ranges and docs not appear to have any unusual characteristics The results are comparable to the historical average dating back to 1977 The results do show increases in concentration of several of the parameters especially solids This may be due to the installation of the underdrain and the dry weather prior to sampling

X Flow Mopitoripg Program

The purpose of the flow monitoring program is to gather suffishycient data to properly size the future pipe which will ultimately connect the leachate drain to the City sanitary sewer system

The location of the leachate drain flow monitor rain gauge and drainage area tributary to the leachate drain are shown on Figure 3 page 15

The equipment is inspected weekly following a standard routine to ensure proper operations The flow monitor was taken out of service for repairs from February 11 1983 to March 29 1983 and from April 6 1984 to April 19 1984 Due to freezing temperashytures the rain gauge was taken out of service in December 1983 and was reinstalled on February 28 1984 Otherwise both the flow monitor and rain gauge have recorded data since July 1982

Historically the dry weather flow at the leachate drain headshywall shows the depth of flow in the 18-inch diameter pipe to be 12 inch Recent measurements of the dry weather flow have been about 25 - 30 gallons per minute

NEDA Semi-Annual Report July 31 1984

With regard to maintenance the item of prime importance is the proper operation of the two inlets at the upstream end of the leachate drain and the storm drains throughout the site The hay bales which protect the leachate drain inlet should be replaced periodically to maintain the flow and protect the water quality in the adjacent monitoring wells All storm drain receivers should be kept clear to promote proper surface drainage and thus minimize

leachate production

VI Expansion Area

During this report period underdrains were installed in a portion of the expansion area east of the leachate drain Temporary groundwater monitoring wells were also installed and read twice weekly from the end of March through May Field surveys were also conducted to determine the locations and elevations of ledge out crops The water levels and ledge elevations were plotted and base fill levels determined for lift No 1 See Figure 1 page 10 Five feet of fill are shown between high groundwater or ledge and the base of lift No 1 The quantity of fill required was calculated to be about 10000 cubic yards

Approval of the fill contours for the base of lift No 1 must be obtained from DEP prior to placing waste in this portion of the expansion area

VII Water Quality Monitoring Program

lpound accordance with the Supplement the water quality monitoring program has continued at NEDA although with DEP concurrence the sampling points have changed The sampling points known as the inlet and the weir were deleted from the monitoring program after the April 1982 samples Sampling points known as Wells A B C and D are groundwater samples Surface water samples are taken froiu the pond northwest of the NEDA and the unnamed brook in Wolcott A sample of the leachate is taken from the headwall of the leachate drain These sampling points are shown on Figure 2 page 11 For the purpose of this Report all samples taken were tested for indicator and specific parameters as detailed in the Supplement Laboratory analyses were performed in part by the Citys Water Pollution Control Facility Laboratory and in part by the Ellis A Tarlton Laboratory in Danbury Connecticut Test results are shown in Appendix B

VIII Review of Test Results

A GroundwaterSurface Water

The results of the water quality tests for groundwater and surface water are detailed in Tables 1 and 2 pages 12 and 13 respectively The standards used for judging the quality of groundwatersurface water are the drinking water standards of the 1980 State Public Health Code and the various Public Acts of Congress defined by the US Environmental Protection Agency

Test results of the groundwater monitoring wells Table 1 indicates that in general the current test results are at or below the historical average of results since monitoring began except for solids which show an increase

Table 2 indicates a similar pattern in the test results for the surface water samples Essentially all parameters are at or below historic averages except for a rise in manganese level in the pond

B Leachate

The test results on the leachate sample taken at the leachate drain headwall are shown on Table 3 page 14 The standard used to compare NEDA leachate to other leachate is a summary of the broad range of values found in the American Society of Civil Engineers Manual of Protection No 39 - Sanitary Landfill 1976 Groundwater by Freeze and Cherry 1979 and Solid Wastes by Tchobanoglous Theisen and Eliassen 1977 It appears that the leachate produced at NEDA is within these ranges and docs not appear to have any unusual characteristics The results are comparable to the historical average dating back to 1977 The results do show increases in concentration of several of the parameters especially solids This may be due to the installation of the underdrain and the dry weather prior to sampling

IX Future Water Quality Testing

I

I11

Mercury silver barium and selenium have been deleted from L further testing programs at the four wells the brook in Wolcott and the pond west of NEDA Test results for mercury have been

I negative since the initial testing therefore it must be assumed that the initial tests were in error and mercury is not present at the site No selenium hexavalent chromium or silver has been detected in any samples since testing began and barium has only been detected in traces well below drinking water standards Barium mercury selenium and silver have also been deleted from the testing program at the leachate headwall as no significant quantities have been found in the leachate

X Flow Mopitoripg Program

The purpose of the flow monitoring program is to gather suffishycient data to properly size the future pipe which will ultimately connect the leachate drain to the City sanitary sewer system

The location of the leachate drain flow monitor rain gauge and drainage area tributary to the leachate drain are shown on Figure 3 page 15

The equipment is inspected weekly following a standard routine to ensure proper operations The flow monitor was taken out of service for repairs from February 11 1983 to March 29 1983 and from April 6 1984 to April 19 1984 Due to freezing temperashytures the rain gauge was taken out of service in December 1983 and was reinstalled on February 28 1984 Otherwise both the flow monitor and rain gauge have recorded data since July 1982

Historically the dry weather flow at the leachate drain headshywall shows the depth of flow in the 18-inch diameter pipe to be 12 inch Recent measurements of the dry weather flow have been about 25 - 30 gallons per minute

It is recommended that the present program of data collection be continued in its present form Evaluation of the effect of refuse placement over the extension of the leachate drain into the expansion area will be made as operations continue into that area

XI Recommendations

As previously discussed the final contours of lift No 1 fill to be placed in the expansion area east of the leachate drain must be approved by DEP Placement of wastes to the east of the leachate drain should be delayed until DEP approval is obtained

With regard to maintenance it is recommended the Staff keep the storm drainage and leachate drain system clear and operational This includes the clearing of pipe inlets and the periodic replacement of the hay bales which protect the upstream end of the leachate drain It is also recommended that the drainage swale be kept clear of silt and debris to maintain proper drainage and reduce the possibility of contamination of surface waters in Wolcott

Methane monitoring of the administration building and the leachate drain manholes should be continued

The drainage swale to the north of the paved access road has been kept clear of litter however it is suggested the swale be deepened so the flow will not escape over the pavement and erode the slope to the south of the access road

As stated in previous reports the westerly slopes have been graded and cover placed so that they now present a very good appearance It is suggested that these slopes be learned and seeded in the fall The portions of the southerly slope north of the paved access road have a good growth of vegetation and present a good appearance

We trust the above Report is satisfactory to you and would be pleased to meet with you to discuss its contents Hay we compliment your Staff at NEDA for the job they have done in regard to daily operations and maintenance

Very truly yours

VIII Review of Test Results

A GroundwaterSurface Water

The results of the water quality tests for groundwater and surface water are detailed in Tables 1 and 2 pages 12 and 13 respectively The standards used for judging the quality of groundwatersurface water are the drinking water standards of the 1980 State Public Health Code and the various Public Acts of Congress defined by the US Environmental Protection Agency

Test results of the groundwater monitoring wells Table 1 indicates that in general the current test results are at or below the historical average of results since monitoring began except for solids which show an increase

Table 2 indicates a similar pattern in the test results for the surface water samples Essentially all parameters are at or below historic averages except for a rise in manganese level in the pond

B Leachate

The test results on the leachate sample taken at the leachate drain headwall are shown on Table 3 page 14 The standard used to compare NEDA leachate to other leachate is a summary of the broad range of values found in the American Society of Civil Engineers Manual of Protection No 39 - Sanitary Landfill 1976 Groundwater by Freeze and Cherry 1979 and Solid Wastes by Tchobanoglous Theisen and Eliassen 1977 It appears that the leachate produced at NEDA is within these ranges and docs not appear to have any unusual characteristics The results are comparable to the historical average dating back to 1977 The results do show increases in concentration of several of the parameters especially solids This may be due to the installation of the underdrain and the dry weather prior to sampling

IX Future Water Quality Testing

I

I11

Mercury silver barium and selenium have been deleted from L further testing programs at the four wells the brook in Wolcott and the pond west of NEDA Test results for mercury have been

I negative since the initial testing therefore it must be assumed that the initial tests were in error and mercury is not present at the site No selenium hexavalent chromium or silver has been detected in any samples since testing began and barium has only been detected in traces well below drinking water standards Barium mercury selenium and silver have also been deleted from the testing program at the leachate headwall as no significant quantities have been found in the leachate

X Flow Mopitoripg Program

The purpose of the flow monitoring program is to gather suffishycient data to properly size the future pipe which will ultimately connect the leachate drain to the City sanitary sewer system

The location of the leachate drain flow monitor rain gauge and drainage area tributary to the leachate drain are shown on Figure 3 page 15

The equipment is inspected weekly following a standard routine to ensure proper operations The flow monitor was taken out of service for repairs from February 11 1983 to March 29 1983 and from April 6 1984 to April 19 1984 Due to freezing temperashytures the rain gauge was taken out of service in December 1983 and was reinstalled on February 28 1984 Otherwise both the flow monitor and rain gauge have recorded data since July 1982

Historically the dry weather flow at the leachate drain headshywall shows the depth of flow in the 18-inch diameter pipe to be 12 inch Recent measurements of the dry weather flow have been about 25 - 30 gallons per minute

It is recommended that the present program of data collection be continued in its present form Evaluation of the effect of refuse placement over the extension of the leachate drain into the expansion area will be made as operations continue into that area

XI Recommendations

As previously discussed the final contours of lift No 1 fill to be placed in the expansion area east of the leachate drain must be approved by DEP Placement of wastes to the east of the leachate drain should be delayed until DEP approval is obtained

With regard to maintenance it is recommended the Staff keep the storm drainage and leachate drain system clear and operational This includes the clearing of pipe inlets and the periodic replacement of the hay bales which protect the upstream end of the leachate drain It is also recommended that the drainage swale be kept clear of silt and debris to maintain proper drainage and reduce the possibility of contamination of surface waters in Wolcott

Methane monitoring of the administration building and the leachate drain manholes should be continued

The drainage swale to the north of the paved access road has been kept clear of litter however it is suggested the swale be deepened so the flow will not escape over the pavement and erode the slope to the south of the access road

As stated in previous reports the westerly slopes have been graded and cover placed so that they now present a very good appearance It is suggested that these slopes be learned and seeded in the fall The portions of the southerly slope north of the paved access road have a good growth of vegetation and present a good appearance

We trust the above Report is satisfactory to you and would be pleased to meet with you to discuss its contents Hay we compliment your Staff at NEDA for the job they have done in regard to daily operations and maintenance

Very truly yours

City 6f Waterbury NEDA Semi-Annual Report July 31 1984

XI Recommendations

As previously discussed the final contours of lift No 1 fill to be placed in the expansion area east of the leachate drain must be approved by DEP Placement of wastes to the east of the leachate drain should be delayed until DEP approval is obtained

With regard to maintenance it is recommended the Staff keep the storm drainage and leachate drain system clear and operational This includes the clearing of pipe inlets and the periodic replacement of the hay bales which protect the upstream end of the leachate drain It is also recommended that the drainage swale be kept clear of silt and debris to maintain proper drainage and reduce the possibility of contamination of surface waters in Wolcott

Methane monitoring of the administration building and the leachate drain manholes should be continued

The drainage swale to the north of the paved access road has been kept clear of litter however it is suggested the swale be deepened so the flow will not escape over the pavement and erode the slope to the south of the access road

As stated in previous reports the westerly slopes have been graded and cover placed so that they now present a very good appearance It is suggested that these slopes be learned and seeded in the fall The portions of the southerly slope north of the paved access road have a good growth of vegetation and present a good appearance

We trust the above Report is satisfactory to you and would be pleased to meet with you to discuss its contents Hay we compliment your Staff at NEDA for the job they have done in regard to daily operations and maintenance

Very truly yours
