1.0 INTRODUCTION

A Site Investigation was performed by Gila River Indian Community (GRIC) Department ofEnvironmental Quality (DEQ) at the Boundary Site in January and February 2002 (Figure 1). Thissite was used by various crop dusting companies as a base of operations from 1959 until the early1980"s (Figure 2). The objective of the Site Investigation was to confirm and supplement theconcentrations of toxaphene in soil that were reported in the CERCLA Site Inspection Report,prepared by URS Greiner, Inc. (URSG), and dated April 23,1997 (URSG 1997) and to evaluate theeffectiveness of remediated soil at the site. The following presents the investigative methodologyused, the results of that investigation, and a discussion of the conditions that exist at the site.

1.1 SITE LOCATION

The site is located along the GRIC boundary on the west side of 51st Avenue near the intersectionwith Komatke Lane in Section 20 of Township 1 South, Range 2 East of the Gila and Salt RiverBaseline and Meridian (Figure 1). The former airstrip was configured in a northeast-southwestdirection, with the northeast end adjacent to the crop dusting businesses operation buildings. TheBoundary Site includes the Homesites for the Thomas and Yazzie families. However, the Homesitesare not currently being used by either family.

1.2 SITE BACKGROUND

On August 7, 1984, the United States Environmental Protection Agency (USEPA) initiated anemergency removal action by temporarily relocating families living at this site under theComprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Soilsampling had indicated approximately 3,500 cubic yards (yd3) of soil had been impacted bytoxaphene (confined to the Thomas Homesite only). The USEPA removed soil that containedtoxaphene in concentration greater than 1,000 milligrams per kilogram (mg/kg) and transported it toa disposal facility. The remaining soil was treated in-situ by accelerated chemical decompositionand biological degradation. Initially, the treatment of the impacted soil involved chemical treatmentof the soil that included pH adjustment, continual moisturizing, and turning of the soil. Thetreatment method was converted to biological degradation that entailed neutralization and addition ofnutrients to the soil, leveling of the site, changing the sprinkler system to a surface drip system, andcovering the site with plastic sheeting to control evaporation and to enhance the anaerobicenvironment. At the conclusion of the in-situ soil treatment, it was estimated by the USEPA'scontractor, Roy F. Weston, Inc. (Weston), that the concentration of toxaphene remaining in the soilhad been reduced approximately 45 percent. A cap was placed over the site using approximately 200yd3 of soil.

A Risk Assessment was prepared by Roy F. Weston, Inc. (Weston) dated October 24, 1985. TheWeston Risk Assessment concluded that contact or consumption of toxaphene impacted soil could

produce adverse health effects in humans. The assessment indicated a carcinogenic risk of 1 in1,000,000 due to the toxaphene in the soil at the site. Weston estimated that it would requireapproximately 30 years for the toxaphene to naturally degrade to background levels. The assessmentindicated that the residents could return to the site and that they be advised of the implication ofdigging in the cap and soil, the actions that must be taken if the planting of trees or the cultivation ofthe soil, and recommended that a cap monitoring program be developed to monitor the integrity ofthe soil cap.

URS Greiner, Inc. performed soil sampling at the entire site in May and August 1996. Surfacesamples were collected from 54 locations at the site. Five surface soil samples were collected fromthe soil cap at the Thomas Homesite. The remaining soil samples were collected on or around theYazzie Homesite or along the airstrip. Laboratory analysis of the surface samples indicated theconcentration of toxaphene in the 16 soil samples ranged from 2.4 mg/kg to 830 mg/kg (Figure 3).Two surface soil samples collected from soil cap at the Thomas Homesite contained toxaphene inconcentrations of 3.8 mg/kg and 17 mg/kg (Figure 3). A Hazard Ranking System Model is theprimary mechanism USEPA uses to place sites on the National Priorities List (NPL). The HazardRanking System model was also run using Site data to assess the relative threat to humans associatedwith the substance found on the site. Based on the hazard ranking, the site was not eligible forcontinued assessment under CERCLA. In addition, the USEPA recommended that the site not beused for residential, commercial, or industrial activities due to the levels of toxaphene found on thesite.

2.0 FILE AND AERIAL PHOTOGRAPH REVIEW

A file and aerial photograph review was performed to evaluate the effectiveness of the remedialeffort performed at the Thomas Homesite and the results of the subsequent surface soil sampling atthe entire site. The results of the file and aerial photograph review are presented below.

2.1 FILE REVIEW

The GRIC DEQ does not have all of the documentation related to the work performed in 1984 and1 985 at this site in its files. In particular, documentation of the remedial effort performed by Westonon the impacted soil at the Thomas Homesite is very limited. Documentation that provides adetailed description of the remedial effort, including the volume of soil removed, the disposition ofthe removed soil, and the volume of soil involved in the in-situ remediation is not available. GRICDEQ was unable to evaluate the effectiveness of the remedial effort. Therefore, additional soilsamples were collected from below the soil cap during this investigation to aid in the evaluation. Therecommendations made in the Weston Risk Assessment (Weston, 1 985) do not appear to have beenimplemented. No documentation was available in the file to indicate a plan to maintain the soil capwas prepared.

The evaluation of the site focused on the work performed by URS Greiner in 1 996. The evaluationpresented the following concerns:

. Thirteen (13) of 20 soil samples collected by URS Greiner in 1996 at the Yazzie Homesitecontained toxaphene at concentrations exceeding the non-residential soil remediation level(NR-SRL) adopted by the State of Arizona as a cleanup goal. The concentrations oftoxaphene in the 13 soil samples ranged from 17 mg/kg to 830 mg/kg (Figure 3).

• Samples collected along the western boundary of the study area in January 1997 exceededthe NR-SRL for toxaphene, indicating additional sampling was required to completely "characterize the western extent of impacted soil (Figure 3).

In addition, the field screening performed by URS Greiner in May 1996 using the enzymeimmunoassay test kits was conducted at ambient temperatures of approximately 100 degreesFahrenheit (F). The ambient temperatures were significantly greater than the test kit's recommendedtemperature range (60 to 80 degrees F). The results of those tests should be considered suspect andany field decisions made during the 1996 investigation that were based on those results wouldrequire additional evaluation and selected sample locations may require re-testine.

2.2 AERIAL PHOTOGRAPH REVIEW

To review the activities at the site over time, an aerial photo review was performed. The reviewfocused on historical building activity, historical land use, and identification of any other potentialareas of concern at the site. Aerial photographs of the site were available beginning in 1963. Thearea was periodically photographed through the end of the 1970's and beginning in the 1980's thearea was photographed every two to three years to the most recent photograph taken in 2000. Theaerial photographs used for this review were dated June 13, 1963, January 3, 1972, December 14.1978, December 29, 1986 (GRIC DEQ also has a USEPA supplied picture dated January 3,1986),December 25, 1991, February 12, 1995, and January 13, 2000. A copy of these photographs arepresented in Figures 4, 5, 6, 7, 8, 9, and 10. A detailed description of the changes that occurred atthe site over time is presented below.

• In 1963, one small building is present in the area just to the north of the Thomas Homesite.The airstrip is clearly visible with the northeast end located at the edge of the ThomasHomesite. The Thomas Homesite appears to be the turnaround area for the crop dusterplanes. The fields to the west of the irrigation ditch are being used for agricultural purposes.The land to the south is undeveloped and there has been very limited development of theHomesites east of 51st Avenue and south and of the site (Figure 4).

. In 1972, the smaller building was replaced by three buildings and a potential above groundtank is located on the property north of the Thomas Homesite. The Thomas Homesite hasnot been developed. The buildings are not large enough to house the planes, so one or bothof the two buildings adjacent to the Thomas Homesite may have been used for pesticidestorage. The building on the northern portion of the site may be the residence/office for thebusiness. The structure that appears to be an above ground storage tank may have been usedto store fuel for the planes. Two crop dusting planes are visible parked adjacent to 51st

Avenue. The surrounding land use has not changed. There has been increased developmentof the Homesites east of 51st Avenue and south and of the site (Figure 5).

• In 1978, the two building adjacent to the Thomas Homesite are now one large building,another building was added to the western boundary and the residence/office building islarger. One plane is parked near the large building (perhaps a hanger) on the northern edgeof the Thomas Homesite. In addition, six (6) planes are parked adjacent to the northeast endof the airstrip, adjacent to the northwest corner of the Yazzie Homesite. This picture showsthe first development of the Thomas Homesite with two (2) new structures and some otherunidentifiable objects near the structures. The surrounding land use has not changed. Therehas again been increased development of the Homesites east of 51st Avenue and south and ofthe site (Figure 6).

In 1986, the crop dusting business has ceased operations and the airstrip does not appear tohave been used in some time due to the increased vegetation that is growing on it. TheThomas Homesite has had additional development with the addition of the home in thecentral part of the site and another structure (possibly a storage container) along the westernboundary of the site. A picture provided by the EPA taken in January shows two homes, abarn and the storage container on the site (the picture is too large to include in this report). Inthe December photograph, the home located on the eastern boundary has been removed. Thesurrounding land use has not changed. The development of the Homesites east of 51s'Avenue and south and of the site has not changed significantly (Figure 7).

In 1991, there is very little change in the development of the Thomas Homesite. However,there are a large number of items being stored along the perimeter of the Site. According tothe Thomas Family, the items were concrete pipes that the Thomas's were allowing to bestored on their property. Some of the land to the west of the site does not appear to becurrently used for agricultural as it was in the past. The land to the north continues to beused for agriculture. In addition, a new housing development has been built south of the site.The development of the Homesites east of 51st Avenue and spurn and of the site has notchanged significantly (Figure 8).

In 1995, the structures on the Thomas Homesite appear to have been removed. A trailer hasbeen installed on the Yazzie Homesite and the vegetation surrounding the trailer has beenremoved. The surrounding land use has not changed significantly since 1991 (Figure 9).

In 2000, the Trailer on the Yazzie Homesite has been removed. The new intersection forKomatke Road (the 4 lane road that provides access to the Vee Quiva Casino) has beenconstructed opposite the Yazzie Homesite. The surrounding land use has not changedsignificantly since 1995 (Figure 10).

3.0 FIELD SAMPLING

GRIC DEQ conducted a site walk on December 20. 2001. The objective of the site walk was toassess the condition of the cap that was placed over the Thomas Homesite and the condition of theYazzie Homesite. The cap on the Thomas Homesite appeared to be intact, however there appearedto have been some localized erosion caused by surface run-off of rainwater. In addition, there havebeen reports that the cap had been breached in a number of areas due to fence construction and other "~rf

r

To further evaluate areas of potential concern at the Boundary Site, GRIC DEQ performed limitedsoil sampling and analysis that began on January 28,2002. Due to a breakdown of the sampling rigon January 28,2002, the remaining sampling was postponed until February 11,2002. The objectiveof the soil sampling and analysis was to evaluate residual concentrations of toxaphene below the capat the Thomas Homesite, to further assess the elevated concentrations of toxaphene on and aroundthe Yazzie Homesite, and to evaluate the need for additional characterization of the soil west of theYazzie Homesite. Four (4) composite and five discrete soil samples were collected from the ThomasHomesite and eight composite and four discrete soil samples were collected from the YazzieHomesite (Figure 3).

The soil samples were collected from 0.5 to 1-foot below ground surface (bgs) at 12 locations at oradj acent to the Yazzie Homesite, 0.5 to 1 -foot bgs in the disturbed portion of the soil cap, and from 2feet to 2.5 feet bgs (below the soil cap) at the Thomas Homesite. Two (2) samples were collected at2 feet to 2.5 feet bgs and 5 to 5.5 feet bgs for a depth profile within the disturbed portion of the soilcap.

The majority of the soil samples were collected using a Geoprobe sampling rig. The Geoprobeutilizes a hydraulic hammer to drive a 1 -inch outside diameter rod to the desired sample depth. Theprocedures and associated equipment used to collect soil samples with a Geoprobe sample rig are asfollows:

. The sample equipment was decontaminated prior to collection of each soil sample. Thesample equipment was washed in tap water and non-phosphate detergent, rinsed with tapwater, and then rinsed with distilled water. The sample equipment was allowed to air dry ona clean plastic sheet.

. The Geoprobe sampler uses a 22-inch long, 1 -inch inside diameter stainless steel tube. Soilsamples was collected in a decontaminated, 22-inch long, 1 -inch diameter clear PVC linerinserted into a decontaminated sampler.

. At the Yazzie Homesite, the sampler was attached to the Geoprobe push rod and the samplerwas driven from the surface through the sample interval using the Geoprobe sample rig'shydraulic hammer. At the Thomas Homesite, the sampler was driven from approximately 2feet bgs through the sample interval. No lubricants were applied to either the end cap ordrive shoe.

. The sampler and drive rod was removed from the borehole and verification of samplecollection was performed by looking into the sampler drive shoe.

t The sample liner was removed from the sampler. The soil sample was placed into 4-ounceglass jars that were supplied by the laboratory. The sample jars were labeled, logged on asample chain-of-custody form, and placed in a sample cooler maintained at 4 ± 2 degreesCelsius (C).

|v, Composite soil samples were collected from selected sample locations at the site. The compositesample were prepared from soil that is collected from a minimum of four separate locations in a 10foot by 10 foot area surrounding previous soil sample locations by the following procedure:

• Four (4) discrete soil samples were collected from approximately 5 feet around a previoussoil sample location that 1996 sample analysis indicated elevated concentrations oftoxaphene were present.

. An equal volume of soil was collected from each discrete soil sample location using theGeoprobe or a stainless steel spoon. An equal amount of soil from each discrete soil samplewas placed in a decontaminated stainless steel container.

4.0 LABORATORY ANALYSIS

Soil samples collected at the site were delivered to Del Mar Analytical Laboratory, an ArizonaDepartment of Health Services (ADHS) licensed laboratory, in Phoenix for analysis. The analysesselected for the soil samples collected during this investigation was based on the potential chemicalconstituents that may be present in the near-surface soil due to historical activities at the site. Thesoil samples were analyzed for the following:

. Chlorinated pesticides using USEPA Test Method 8081.

The results are presented graphically in Figure 3 and summarized in Table 1. The laboratory reportis presented in Appendix B.

A total of 24 soil samples. 22 primary samples and two duplicates, were submitted for analysis.Nine (9) pesticides, chlordane; 4,4'-DDD; 4,4'-DDE; 4,4'DDT; Endosulfan I; Endrin Aldehyde;Endosulfan Sulfate; dieldrin; and toxaphene, were detected in these soil samples. Toxaphene wasdetected in concentrations exceeding the practical quantitation limit (PQL) in 23 samples, rangingfrom 0.48 mg/kg in sample SS-46-comp to 710 mg/kg in sample SS-05-comp. Ten (10) samplescontained concentrations of toxaphene greater than the NR-SRL of 17 mg/kg. Chlordane wasdetected in concentrations greater than its PQL in 19 soil samples, ranging from 0.027 mg/kg insample SS-48-comp to 12 mg/kg in sample SS-01-comp. Nineteen (19) soil samples contained 4,4'-DDE in concentrations greater than its PQL, ranging from 0.02 mg/kg in sample Thomas-comp to7.2 mg/kg in sample SS-09-comp. The remaining compounds were detected at concentrationslightly above their respective PQLs.

Three (3) quality control samples, two equipment blanks and one field blank, were also submitted foranalysis. These samples did not contain the analytes of concern in concentrations exceeding theirrespective PQL.

5.0 QUALITY CONTROL FOR MEASUREMENT DATA

The QA/QC procedures for soil sample collection included the collection of two blind fieldduplicates, two equipment blanks and one field blank . Duplicate samples were collected at afrequency of one duplicate sample per 10 samples collected. One (1) duplicate soil sample wascollected from a composite location and one duplicate soil sample was collected from a discretesample location. The composite soil sample duplicate was collected from the same mixing bowl asthe primary composite sample. The discrete soil sample duplicate was collected from a locationadjacent (within 6-inches) to the primary sample location. The equipment blanks were collected bypouring distilled water through the soil sampler into a sample container provided by the laboratory.One sample was collected prior to collecting the first soil sample and the second was collectedfollowing collection of the last sample to monitor for cross-contamination. The field blank wascollected by pouring distilled water directly into a sample container provided by the laboratory in thesampling area to monitor the effect of ambient conditions on the decontamination process. Thesample was noted on the sampling form along with a sketch of the sample location. The blanksamples was labeled, logged onto a chain-of-custody form, stored in an insulated cooler maintainedat approximately 4 " 2 degrees C, and transported to the laboratory for analysis. The equipment andfield blank samples were analyzed for chlorinated pesticides using USEPA Test Method 808 1 . Atemperature blank accompanied each sample cooler and the temperature of the cooler was recordedon the chain-of-custody form upon receipt of the samples at the laboratory.

The QA/QC procedures utilize the data quality indicators (DQIs) precision, bias (accuracy),representativeness, comparability, completeness, and sensitivity as guides for evaluating theacceptability and utility of the laboratory analytical data. The DQIs were then compared to themeasurement requirements as an assessment of meeting the data quality objectives (DQOs) for theproject. The DQOs represent the qualitative and quantitative objectives that ensure the datagenerated during this investigation meet the needs of the project. The DQOs are dependant on theintended uses of the data, and are based on the premise that the ultimate use(s) of a data set shoulddictate the quantity and quality of these data (USEPA 1994 and 1998).

Precision is a measure of the reproducibility of concentrations reported for duplicate soil samplescollected from the same location. Precision is calculated by determining the relative percentdifference (RPD) between duplicate samples. The precision objective for soil field duplicates was anRPD of 50 percent. The RPD for each duplicate sample was calculated by the following formula:

RPD=

The results of the precision evaluation are presented in the data validation report (Appendix C) andare discussed below in Data Validation.

Accuracy is the degree to which the measurement data approach the "true" value for each analyte.For soil samples, accuracy is assessed by calculating the percent recovery for a sample spiked withthe analyte of concern (Laboratory Control Samples [LCSs], surrogates, matrix spikes). The resultsof the accuracy evaluation are presented in the data validation report (Appendix C) and are discussedbelow in Data Validation.

Representativeness refers to the comparability of the sample collection procedures to thosedelineated in the work plan, and to the degree to which the analytical data represent the surface andsubsurface contaminant concentrations. Representativeness was accomplished by adhering toconsistent field sampling and analytical procedures.

Completeness is defined as the ratio of acceptable validated laboratory measurements to the totalnumber of planned measurements for this investigation. The completeness objective for soil samplescollected during the investigation was at least 90 percent.

_, , ( Number of Validated Measurements V , _ _Percent Completeness = * 100

^ Total Number of Planned Measurements J

100 percent of the total number of planned measurements were considered valid by the datavalidator.

Comparability is an evaluation of the relative consistency of the laboratory measurement data.Since comparability cannot be measured quantitatively, professional judgment is relied upon.Internal comparability was achieved by adhering to consistent sample collection procedures andanalysis methods throughout the investigation.

The Practical Quantitation Limit (PQL) is the lowest concentration of a specific analyte that can bereasonably achieved within the specified limits of the precision and accuracy DQOs during routinelaboratory operations. All analytes that have a concentration greater than or equal to its respectivePQL was reported.

Data Validation

Data validation is a review of the supplied analytical data documentation to assess data quality. Allanalytical data for which validation is performed was evaluated against the DQOs presented in theWork Plan and the analytical method criteria. The Project Manager validated data obtained from

field measurements by checking procedures used in the field and comparing current measurementswith historical data and with field QC checks. To allow comparison of data from different samplingepisodes, results were reported in the same units.

A qualified professional at Quality By Design, Inc performed data validation of laboratory analyticalresults. All analytical data were reviewed and evaluated according to the criteria established in theContract Laboratory Program (CLP) guidelines described in the following documents:

. National Functional Guidelines for Organic Data Review (EPA, 1994)

. Laboratory Documentation Requirements for Data Validation (EPA, 1997)

All qualifications were recorded in the validation report and all professional judgment assessmentswere clearly documented in Quality By Design's Data Verification Report dated March 29, 2002(Appendix C). Each analytical data package was assessed using the laboratory established precisionand accuracy limits. The following summarizes the data validation results:

. The continuing calibration for several compounds were out of the criteria of 80 to 120percent in a number of samples. In 8 samples, the recoveries indicated low bias. Thesamples containing detectable concentrations of any compound were flagged with a "J" andcompounds that were not detected above the PQL were flagged with a "UJ". Both flagsindicate the values are estimated. In 17 samples, the recoveries indicated a high bias. Thesamples containing detectable concentrations of any compound were flagged with a "J". Noqualifier flags were recommended for non-detect results.

« The surrogate recoveries for two compounds were not calculable due to dilution of thesamples. No data qualifier flags were recommended.

• The reporting limits for a number of compounds were raised due to high concentrations oftoxaphene in the samples. No data qualifier flags were recommended.

« The RPD for duplicate samples were within the 50 percent criteria for soil samples for allcompounds except toxaphene in duplicate samples Thomas-1-0.5 and Thomas 4 which was80 percent.

The data, as qualified by Quality By Design, are acceptable for use and the laboratory analyses weregenerally within the requirements of the referenced method.

6.0 DISCUSSION

Former activities at the Boundary Site have resulted in contamination by pesticides to the surfaceand near surface soil. The majority of this site is allotted land belonging to the Thomas and YazzieFamilies. The Thomas and Yazzie families have not been able to live on the property due to thepotential adverse health effects that may be caused by the contaminated soil. The families desire toreclaim their Homesites, coupled with the dynamics of growth of the area, including the operation ofa new casino nearby, the planned construction of a new freeway through the area, and planned futuregrowth by GRIC, means the site may require additional characterization and remediation ofpesticide impacted soil.

There are several factors that make this site a strong candidate for further characterization and/orremediation. Among them:

• The former activities at this site has potentially impacted the non-Communityproperty north of the Thomas Homesite. The crop dusting facility, it's work areas.buildings and storage areas, was located on a triangular piece of land north of theCommunity property boundary. GRIC DEQ has no record of characterization workbeing performed on this property.

. The area that was subjected to chemical treatment and biological degradationcontains residual concentrations of toxaphene that exceed the NR-SRL adopted bythe State of Arizona. ' /

The soil cap on the Thomas Homesite was not maintained properly and hasexperienced significant disturbance. The breaches in the cap include an approximate " r>J"3,280 square foot (ft2) portion of the soil cap that was removeo>fiorth of a buildingpad to facilitate storm water drainage, a 9 ft2 pit adjacent to the remaining building,various post holes for fencing, and disturbances cause by erosion during stormevents. These disturbances to the soil cap and the concentrations of residualtoxaphene in the exposed soil increases the potential for human exposure on and offof the site.

As the area continues to be developed and more people work and live in the area, thepotential for adverse health impact to the local residences and businesses willincrease. The completion of the planned new freeway through the area will likelyaccelerate growth in this area.

Five (5) sample locations from the 1996 investigation, SS-01, SS-02, SS-03, SS-05, and SS-09.contained concentration of toxaphene of 350 mg/kg, 310 mg/kg, 120 mg/kg, 190 mg/kg, and 450mg/kg, respectively. Confirmatory sampling preformed by GRIC DEQ from these same sampleareas contained toxaphene concentrations of 610 mg/kg, 110 mg/kg, 110 mg/kg, 710 mg/kg, and 460mg/kg, respectively. A comparison of these results indicates that natural degradation of toxaphenehas not occurred since 1996 and that toxaphene will continue to persist in the soil until more activemeasures are implemented to remove it.

8EC CALIBRATION CHECK CRITERIAILORINE PESTICIDES BY GC (EPA 3550/8081A)

Per Method 8000B of SW-846, the percent recovery of the calibration checks for GC analyses must be within = 15% fromthe true value for each individual compound or the average % recovery of all compounds in the calibration check solution mustbe within ±15% recovery. Per Method 8000B, the end user is to be notified if the latter situation occurs.

The % recovery for the following individualin the calibration check solution was within

compounds fell outside the ± 15% criteria, however the average % recovery± 15%, thus meeting the overall calibration check criteria.

Dear Mike:

We have completed the laboratory data review for one sample delivery group (SDG) for theSoil and Water Sampling Events of January 28, and February 11. 2002, for the Boundary SiteProject, in partial compliance with the signed Purchase Order No. 134940.

This report consists of a narrative (which describes the criteria that we reviewed for eachitem of the validation), a summary table, copies of the laboratory reports with any correctionsmarked in red on them. We recommend:

> That a copy of this report, in its entirety, including the written communicationswith the laboratory and the laboratory's resubmitted data, be attached to therespective laboratory reports; and

> That the modified laboratory reports, i.e., reports on which we mark changes inred ink, be used to replace the same pages in the original laboratory report fromwhich any future copies will be made.

We thank you for the opportunity to be of service to your company. Please do not hesitateto call if there are any questions.

Sincerely,

Laboratory Sciences, Inc., d.b.a. Quality by Design (QBD). has completed an EPA Level 3 DataVerification on the submitted data packages in accordance with Purchase Order 134940.

The reporting format and criteria for recommending data qualifying flags for this data set aredescribed in the EPA "Functional Guidelines for Evaluating Inorganics Analyses", as revised.1994; or using criteria listed in the method referenced. Data may be qualified for any of thefollowing reasons:

1. By the laboratory prior to receipt by the reviewer2. Because of laboratory deviation from the designated method3. Because the data may not meet the criteria listed in the reference above4. By the professional judgment of the reviewer

This data verification report consists of several sections, each of which are formatted to followFunctional Guidelines, but which also include subsections discussing QBD contacts with thelaboratory, other comments, and a summary table of data qualifiers.

The data set consists of two data packages of 84 pages from Del Mar Analytical in Phoenix,Arizona, and contains data for the samples shown in Table 1. The data reviewer and seniorreviewer are shown in Table 2.

Each data set includes an analytical data package for each sample, copies of the completed COCforms, and a QC data package. The analytical data package includes analytical results, blanksample results, both laboratory and client sample identifications, appropriate dates but not times,method reporting limits, method references, surrogate recoveries as appropriate, the laboratory'sname and address, and the initials of the person releasing the data. The custody forms includethe receipt of the sample. The QC data package includes a tabular list of the laboratory's sampleidentification, spiking concentrations, recoveries, percentage calculations, and acceptancewindows.

Discussion: The continuing calibration associated with Samples Thomas-1, SS-47-COMP, SS-1-COMP. SS-2-COMP, SS-6-COMP, SS-48-COMP. Thomas-Comp. and Yazzie-1 for several compounds had percent recoveries that were out of the criteria of 80to 120 percent. Since the recoveries indicated low bias, the associated positiveresults have been flagged "J" to indicate estimated values, and the non-detectresults have been flagged "UJ" to indicate estimated reporting limits.

The continuing calibration associated with Samples SS-47-COMP, SS-1-COMP,SS-2-COMP, SS-3-COMP. SS-9-COMP, SS-11-COMP, SS-17-COMP, SS-48-COMP. Airstrip-Comp. Thomas-Comp. Yazzie-1. Yazzie-2, Yazzie-3. Yazzie-4.Thomas-2, Thomas-3. and Thomas-4 for several compounds percent had arecoveries result that were out of the criteria of 80 to 120 percent. Since theresponses indicated a high bias, the associated positive results have been flagged"J" to indicate estimated values. No data qualifier flags are recommended fornon-detect results.

3. Blanks and Checks for Contamination

The frequency of analysis and the results for instrument and method blank analyses werereviewed. Equipment and field blanks were also evaluated if identified in the group of samples.Either no analytes were detected or, if detected, levels were below the reporting limit.

4. Surrogate Recovery

Surrogate spikes were added to all samples. QC checks, and blanks as required by the referencedmethod. All data reviewed were acceptable, except as noted below.

Discussion: The surrogate recoveries for tetrachloro-m-xylene and decachlorobiphenyl werenon-calculable due to large dilutions in Samples Thomas-1, SS-49-COMP, SS-1-COMP, SS-2-COMP, SS-3-COMP, SS-5-COMP, SS-6-COMP, SS-9-COMP, SS-11-COMP, SS-17-COMP, Airstrip-Comp, Thomas-1-0.5, and Thomas-4. No dataqualifier flags are recommended.

5. Precision and Accuracy

Results for precision (RPD) and accuracy (percent recovery) were reviewed for spikes andduplicate spikes (MS/MSDs, BS/BSDs and/or LCS/LCSDs) to determine that the checks wereanalyzed at the frequency required by the referenced method and the results met the requirementsof the project. All data reviewed were acceptable, except as noted below.

Discussion: The laboratory's case narrative indicated that MS/MSD pairs were not reportedwith the analyses associated with all soil samples in both SDGs. due to matrixinterference. The laboratory reported LCS/LCSD pairs to measure precision andaccuracy. All percent recoveries and RPDs were within laboratory criteria.

A MS/MSD pair was not reported with the set of analyses associated withaqueous Samples EQ-1. FB-1. and EQ-2. Instead, the laboratory reported aLCS/LCSD. All percent recoveries and RPDs were within laboratory criteria.

6. Second Source Calibration Checks

The laboratory did not provide the documentation required for this review.

7. Compound Quantitation and Reported Detection Limits

Using judgment based upon the information provided and typical calibration and extractionprocedures, it appears as if no quantitation exceeded the typical highest calibration standard forthe test, that dilutions were reported for samples with high values, and that reporting limits havebeen correctly adjusted for dilutions and extraction amounts. The reporting limits met method orcontractual requirements. All data reviewed were acceptable, except as noted below.

Discussion: The reporting limits for several compounds associated with Samples Thomas-1,SS-49-COMP, SS-1-COMP, SS-2-COMP, SS-3-COMP. SS-5-COMP, SS-6-COMP. SS-9-COMP. SS-11-COMP, SS-17-COMP, Airstrip-Comp. Thomas-1-0.5. and Thomas-4 were raised due to high concentrations of target analytes in thesamples. No data qualifier flags are recommended.

8. Field Duplicates

Field duplicates were collected and analyzed. Sample Airstrip-Comp is a duplicate of SampleSS-15-COMP. Sample Thomas-4 is a duplicate of Sample Thomas-1-0.5. Test results werereviewed, and where positive results were found, the RPD was calculated. All analytes, exceptthose listed in the table below, were reported as non-detect.
