GRAY DAVIS, Governor

December 24, 2001

Bernard Kersey General Manager City of San Bernardino P.O. Box 710 San Bernardino, CA 92402

Subject: Source Water Quality Monitoring Frequency for Compliance Cycle Beginning January 1, 2002 (System No. 361 0039)

Dear Mr. Kersey:

The current nine-year water quality monitoring compliance cycle began on January 1, 1993, and will be ending on December 31, 2001. In August 1993, you were advised of your source water monitoring frequencies for the current cycle.

This letter is to advise you of your source water quality monitoring frequency for the next nine-year compliance cycle beginning January 1, 2002. Please find the enclosed Minimum Water Quality Monitoring Frequency table for the existing sources supplying your water system. The monitoring frequencies indicated in the table do not apply to sources exceeding an MCL, or those sources subject to additional monitoring as required by the Department due to detected contaminants at levels of concern. Periodic monitoring for bacteriological quality of sources and the water in the distribution system is not included in this letter, but is required.

The enclosed tables indicate the vulnerability of your groundwater sources, except for vulnerability to MTBE. Vulnerability to MTBE has been previously determined for each of your sources in our letter dated July 24, 2001. The vulnerability classification for your sources may be modified following completion of your Drinking Water Source Assessment Program documents.

Monitoring frequencies for General Mineral, General Physical, Inorganic Chemicals, and Radiological Chemicals will remain the same as in the current nine-year cycle (1993-2001 }. Monitoring for these contaminant groups will continue to be due at the appropriate frequency from their last sampling dates.

For Volatile Organic Chemicals (VOCs) monitoring will be due three years from their last sampling date for groundwater sources. If the date of your last VOC

www.consumerenergycenter.org/flex/index.html

2002 Compliance Cycle Monitoring Frequencies December 24, 2001 Page 2

monitoring is more than three years ago, then VOC monitoring must be completed in 2002.

The enclosed table does not give your sources' vulnerability to MTBE as indicated in our letter dated July 24, 2001. Please follow the guidance in the MTBE letter to complete the initial MTBE monitoring requirements. Once the initial monitoring requirements are complete, a waiver for MTBE monitoring for a three-year period may be applied tor those sources designated as "nonvulnerable" to MTBE. The enclosed table gives the monitoring frequency for MTBE upon completion of the initial MTBE monitoring requirements.

During the previous compliance cycle, waivers were granted for Synthetic Organic Chemical (SOC) monitoring following the initial monitoring period. With the upcoming compliance cycle beginning January 1, 2002, these waivers will have expired. Monitoring tor SOCs may be necessary within three years of either the last SOC monitoring date, or the expiration date of your last SOC monitoring waiver.

You may apply for a waiver from SOC monitoring for a three-year period if all sample results from previous monitoring were non-detect. If you have conducted SOC monitoring for your sources since January 1, 1999, you may apply for a waiver from monitoring during the first compliance period if all results were nondetect. The period of the waiver shall be limited to three years, and may be renewable. Please note that waivers will not be given for monitoring of DBCP, EDB, and simazine, and monitoring for these three constituents will be required every three years.

In order to reduce the amount of SOC monitoring required during the next three years, the Department will allow you to' sample from representative sources of your supply. The sources designated as representative sources must draw from the same groundwater basin as the sources they represent. Representative sampling must be conducted from a minimum of ten percent of your sources, or least one source within each groundwater basin, whichever provides the greater number of samples. Please submit a plan for review and approval of the sources designated as "representative" before SOC monitoring is conducted. The plan must include a schedule for rotation of sampling among the sources represented. Representative sampling according to this plan will only be allowed for SOC monitoring.

The monitoring schedule does not indicate monitoring frequencies for the nine unregulated (UCMR) chemicals. Please refer to our letter dated February 15, 2001, for information on UCMR chemical monitoring requirements.

This monitoring schedule does not supercede any increased monitoring frequency required by the Department due to a detection of a contaminant. This monitoring schedule also does not apply to new sources. New

2002 Compliance Cycle Monitoring Frequencies December 24, 2001 Page 3

sources must complete the initial monitoring requirements before this monitoring schedule will apply to those sources. Please contact the Department for the additional monitoring requirements when a contaminant has been detected, or for the initial water quality monitoring requirements for new sources.

It is your responsibility to review past water quality data and determine when the next sample is due for these constituents, using the frequencies provided in the attached table. Your water quality monitoring plan should be updated to reflect the monitoring frequencies outlined in the attached table. Please submit a copy of the revised water quality monitoring plan when completed.

If you have questions regarding this letter, or attached monitoring table, please contact Oliver Pacifico at (909) 383-5468.

for Consideration of the Permit Amendment Application from the City of San Bernardino Municipal Water Department

November 2004

State Department of Health Services Division of Drinking Water- Field Operations Branch

San Bernardino District Yen Tran, P.E., Associate Sanitary Engineer

I. PURPOSE

By application dated September 17, 2004, the City of San Bernardino Municipal Water Department (hereafter SBMWD) applied for a permit amendment to allow the SBMWD to operate the Muscoy Operable Unit (Muscoy OU) which includes the addition of five US EPA extraction wells (EPA Well Nos. 108 - 112), the expansion of the 19th Street GAC Plant from 4.3 MGD to 22.5 MGD, and the addition of Encanto Park pumping plant and raw water transmission main. This report outlines recommendations regarding the issuance of an amended permit to the SBMWD.

The SBMWD operates under a Domestic Water Supply Permit (Permit No. 03-13-99P-002) granted by the Department on December 30, 1999. Since the issuance of the full permit, the Department has granted three permit amendments. Permit Amendment No. 1 was issued on October 1, 2003 for operation of a new Kenwood Well No. 2 located upstream of the Newmark/Muscoy Plumes. Permit Amendment No. 2 was issued on September 17, 2004 for operation of a new Cajon Well No. 4 _located upstream of the Muscoy/Muscoy Plumes. These two wells were not classified as extremely impaired sources. Permit Amendment No. 3 was issued on September 20, 2004 to allow the SBMWD to integrate Victoria Farms Water Company service area into the SBMWD's lower pressure zone and to incorporate the Department's March 2, 2001 approval of the operation of the 2ih and Acacia Street Well nitrate blending plant.

City of San Bernardino MWD Engineering Report- Permit Amendment No. 4 November 4, 2004 Page 2 of 14

II. INVESTIGATION FINDINGS

A. Source of Information

Information for this report was obtained from the documents submitted by the SBMWD with the permit amendment application and the files in the San Bernardino District Office of the Department.

B. Brief Description of System

The SBMWD's office is located at 300 North "D" Street, San Bernardino California 92402 and the system operates under a Domestic Water Supply Permit (Permit No. 03-13-99P-002) granted by the Department on December 30, 1999.

Groundwater is extracted from the Bunker Hill Groundwater basin for use by SBMWD as a source of supply. The western portion of the Basin has been contaminated with volatile organics. The Newmark/Muscoy contamination plume has impacted over onethird of the SBMWD's groundwater supply. The contamination was discovered in the early 1980. The contaminated groundwater has been treated by packed tower aeration (PTA) or granular activated carbon (GAC) systems at six treatment sites.

In the late 1980's the State provided money for the construction four ground water treatment sites, which are Waterman PTA, Newmark PTA, 1 ih Street GAC and 191

h

GAC, to remediate the problem. Studies have shown that drilling wells outside of the plume boundaries would spread the contamination. To address these problems, the SBMWD entered into agreement with the United State Environmental Protection Agency (US EPA) to construct facilities to manage the identified contamination. The Newmark Project is a US EPA Superfund Remedial Action project that manages the cleanup of eight square miles of contaminated groundwater.

The Newmark Project utilizes a large "pump and treat" system to extract contaminated water from three barriers within the contaminated basin and treats this water using GAC and PTA technologies to remove the contaminants. The treated water is then delivered to the SBMWD for delivery to its customers. The EPA Newmark Project consist of three Operable Units (OU). These are the Newmark OU, the Muscoy OU, and the Source OU. The Newmark OU has been in operation since October 1998. The Muscoy OU is covered in this permit amendment and plans to start operation at the end of 2004. The SBMWD with the assistance of the DTSC has entered into a Cooperative Agreement with the USEPA to construct and operate the Newmark OU and the Muscoy OU. The Source OU is being investigated by the US EPA and has not been built to date.

The Newmark OU is located in the northwestern portion of the City of San Bernardino and impacts the Bunker Hill Groundwater Basin. The EPA initiated an interim remedial action for the Newmark OU in 1993. In 1995 the SBMWD entered a cooperative


agreement with the EPA to construct 7 wells, which are EPA Well Nos. 1-7, and reconfigure the treatment train at the existing treatment sites. The Newmark OU was completed in 1998. The Newmark OU treatment sites include Waterman GAC, Newmark GAC and 1 ih Street GAC.

1. The Newmark OU: The Newmark OU is generally located north and east of the Shandin Hills within the Bunker Hill Groundwater Basin. The Newmark OU is an interim action that consists of two Remedy locations, the North Plant and the South Plant. These two Remedy locations include barrier wells, raw water pipelines, and GAC treatment systems. The Remedy plants became functional October 1, 2000.

a) North Plant: This plant contains three barrier wells (EPA Well Nos 6 and 7, Newmark Well No 3), several thousand feet of pipeline and a treatment plant, which is Newmark GAC-PTA Plant. EPA Well Nos. 6 and 7 were constructed using federal funds. Newmark Well Nos. 3 was donated by the SBMWD. The pipeline is Ductile Iron Pipe (DIP) 12 and 16 inches in diameter. The treatment plant consists of seven GAC vessel pairs and two PTA stripping systems. The PT As are used for summer peaking and as a backup to the GAC systems. These three wells are the primary sources of supply for the Newmark GAC-PTA Plant.

b) South Plant: This plant contains five barrier wells, 24,000 feet of large diameter DIP and two water treatment plants. The five wells are EPA Well Nos. 1-5. The two treatment sites are the Waterman GAC (eight vessel pairs)-PTA (2 towers) plant and 1ih Street GAC Plant (three vessel pairs). EPA Well Nos. 1, 2, 4 and 5 are the primary sources of water supply for the Waterman GAC-PTA Plant. EPA Well No. 3 is a primary source of supply for the 1 ih Street GAC Plant.

2. The Muscoy OU: The Muscoy OU is generally located south and west of the Shandin Hills within the Bunker Hill Groundwater Basin. The Muscoy OU is an interim action that consists of five barrier wells, which are EPA Well Nos. 108-112, an existing 4.3 MGD 191

h Street GAC Plant which was expanded to 22.5 MGD, Encanto Park Pumping Plant, and raw water transmission mains. The five wells are drilled in the leading edge of the contaminated aquifer in order to halt further down gradient migration. The wells extract contaminated groundwater from the aquifer, remove the contaminants, and deliver portable water to the SBMWD distribution system. The USEPA is responsible for construction costs, which are administrated through URS Corp. and SBMWD. The SBMWD is responsible for constructing the wells, developing the well sites, and assisting in the oversight of the treatment plant and pipelines. Construction began on the Remedy in November 2000 and the operations are planned to begin at the end of 2004.


a) CEQA/NEPA Compliance: The Department received a letter dated September 7, 2004 from the USEPA, which clarified that the EPA is not required to comply with the National Environmental Policy Act (NEPA) when administering the Comprehensive Environmental Response, Compensation & Liability Act (CERCLA), 42 U.S.C. § 9601 et. seq., commonly known as Superfund. The Muscoy OU is part of the Newmark Groundwater Contamination Superfund Site, which EPA administers under CERCLA. Therefore, they were not required to comply with NEPA.

The well operation is controlled by water level in the storage tank.

c) Drinking Water Source Assessment:

The San Bernardino Valley Water Conservation District has completed the Drinking Water Source Assessment and Protection (DWSAP) evaluation for the SBMWD water system. Due to the relative proximity of source wells EPA Nos. 108- 112 and Olive & Garner, their initial 2-year (Zone A) protection zones overlap resulting in combining all wells into a single "combined well" and redefining and recalculating the protection zones. The PCA inventory and vulnerability ranking portions of the assessment were then conducted for the larger, combined delineation zones and not for each well independently.

The wells are considered most vulnerable to the following activities not associated with any detected chemicals: automobile-gas station, dry cleaners, and underground storage tanks-confirmed leaking tanks. Known contaminant plumes, which are the Newmark-Muscoy Plumes are present within the 2-year, 5-year, and 1 0-year protection zones. The detections of TCE and PCE are listed in the Water Quality section below.

d) Water Quality: Monitoring has been conducted for EPA Well Nos. 108 and 112 since April or June 2001. Monitoring was conducted for EPA Well No. 109 in January 2004, for EPA Well Nos. 110 in June 2004, and for EPA Well No. 111 in May 2004. A full Title 22 monitoring including general mineral/general physical, inorganics, SOCs; four consecutive quarters of


VOCs and radioactivity, two rounds of UCMR, and bacteriological monitoring are completed for EPA Well Nos. 108 and 112. Several chemicals or groups of chemicals have not been analyzed for EPA Well Nos. 109, 110 and 111. The SBMWD is aware of the need of monitoring for these constituents and plans to conduct as soon as the wells are equipped. Details of analytical results are listed below.

• VOCs: Detection of TCE, PCE, cis-1 ,2-dichloroethylene (c-1 ,2-DCE) and dichlorodifluoromethane (Freon 12) are listed below. Other VOCs are non-detect for these 5 wells.

• SOCs, inorganics, radiological, and unregulated chemicals: Constituents in these groups are non-detect or far below their MCLs orAls except for iron. Iron was initially detected at 491 IJg/L for Well 112. This was later resampled and determined to be 238 IJg/L, which is below the MCL. Results of nitrate, perchlorate and iron are listed below. SOCs, radioactivity, tert-butyl alcohol, boron, vanadium, perchlorate, and 1 ,2,3-trichloropropane, monitoring have not been conducted for EPA Well No. 111. Dioxin has not been analyzed for EPA Well No. 110. Boron, vanadium, perchlorate and bacteriological monitoring have not been conducted for EPA Well No. 109.

• Bacteriological Monitoring: Bacteriological monitoring was conducted for EPA Well Nos. 108 and 112 in 2003 and for EPA Well No. 110 in June 2004. The results were total coliform negative with the plate count of less than 500 colonies per milliliter.


Bacteriological monitoring has not been conducted for EPA Well Nos. 1 09 and 111.

e) Public Hearing: The SBMWD has been successfully operating the treatment facilities associated with the Newmark Project for over 5 years. The levels of contamination in the wells currently being treated and in the monitoring wells have been trending down during this time. In all SBMWD wells, the current contamination levels are below the criteria set for Extremely Impaired sources, and some significantly below the MCL set for the contaminants. Therefore due to the levels of contaminations detected, these new wells are not classified impaired sources. No public hearing is required for this project.

f) 191h Street GAC Plant:

• Original plant: The original plant, which was permitted in 1995, consists of four pairs of 20,000-pound GAC vessels (8 vessels). Each pair consists of two GAC vessels in lead-lag configuration. Each pair is capable of treating up to 750 gpm. The original plant treats 3,000 gpm (or 4.32 MGD) of low level (under 25 f.lg/L) PCE/TCE contaminated groundwater produced by 19th Street Well Nos. 1 and 2. The treated water can be delivered to a 258,000-gallon 19th Street booster clear well, delivered directly to the Lower Zone or boosted directly to the Upper Zone for domestic use.

• The expanded plant: The plan is being expanded from 4.32 MGD to 22.5 MGD by adding 12 pairs of 30,000-pound GAC vessels (24 vessels). Each pair is capable of treating up to 1,050 gpm. The expanded plant will treat five EPA new wells (EPA Well Nos. 109-112) along with the existing EPA Well No. 1. EPA Well No. 1 is currently a part of the Waterman GAC site, but it will be shifted to the expanded 19th Street GAC Plant to unload the current Waterman Plant which is operating at maximum capacity. The existing 19th Street Well Nos. 1 and 2 will also be treated through the original GAC vessels. The plant is designed to treat 22.5 MGD up to 250 f.lg/L TCE/PCE to a level of non-detect.

Results of TCE and PCE monitoring conducted every quarter for EPA Well No. 1 show that the well has been contaminated with TCE and PCE. TCE levels are varied from non-detect to 2.3 f.lg/L which are below its MCL. The most recent TCE level is 1.6 f.lg/L. PCE levels are varied from non-detect to 7.8 f.lg/L. The most recent PCE level is 6.0 1-Jg/L which are above its MCL. The well has also been contaminated with nitrate with levels detected range from 26.0 to 30.0 mg/L which are below the nitrate MCL but above a half of


MCL. The most recent analysis shows a nitrate contaminated level of 26.4 mg/L. Perchlorate and arsenic have been non-detect at this well.

• Operations plan for the 22.5 MGD 191h Street Plant: Treated water

from this plant is pumped to the distribution header. Each vessel pair receives water from the header. The water is pumped through the top of the lead vessel, out the bottom, then through the top of the lag vessels. When the lead vessel is exhausted the GAG is replaced with new or reactived GAC. The lag vessel is then switched to a lead position and the old lead vessel to a lag position. Vessel dimensions and criteria are summarized below. Each vessel has a high pressure rupture disk to avoid over pressurization. A backwash is conducted when the differential head loss across the lead vessels reaches 15 psi, which is indicated by a differential pressure gauge between the influent and effluent. This usually occurs between the fourth and sixth months of continuous operations. Backwash expands the filter bed by approximately 35 percent. Backwash run time is 10 to 20 minutes. Backwash effluent is discharged to the storm drain for disposal. This requires a NPDES permit. The operations plan for the treatment facilities was prepared and submitted by the SBMWD along with the permit application.

• GAC change out: Carbon change out is performed by Carbon Activated Corp. When carbon change out occurs, the following procedures will be followed: toxic contaminant leaching profile (TCLP)/8240 tests, iodine test and food chemical codex for all virgin or makeup carbon.

• Chlorination: Gas chlorine is injected into the treated effluent stream prior to entering the booster clearwell, for delivery downstream to maintain a 0.5 - 1.0 mg/L chlorine residual in the effluent. The chlorine feed system automatically adjusts the chlorine feed to match the flow rate in the treatment process. A vacuum system is utilized and auto-switchover assures a constant supply of chlorine.

• Treatment staff and operating times: The SBMWD maintains operator staff on duty 20-hour each day using two shifts with operator staff on stand-by during off hours. All EPA Wells run 24 hours a day and 365 days per year. Other SBMWD's wells run as needed. The treatment plant is scheduled to operate 24 hours per day, 365 days per year. Continuous SCADA monitoring of all systems is sent to a central SCADA control center with remote shutdown capability.

Treatment classification for all treatment plants as well as for individual treatment plants provided by the SBMWD are summarized below. Details of the classifications are attached to this report (Attachment A). The SBMWD must employ at least a T5 chief operator and T3 shift operators to oversee all the treatment plants. The 191

h Street treatment Plant is classified T 4; therefore, an operator with at least a T 4 grade can be classified as a chief operator for this treatment plant and operators with at least a T3 grade can work at this treatment plant as shift operators.

g) Encanto Park pump station: The booster station was designed with 3 units BP-1, BP-2, BP-3 (125 HP motor provided for each unit). The SBMWD plans for a future 4th unit BP-4. This pump station was designed to deliver water from the SBMWD's lower zone, which is fed by 19th Street treatment plant treated water and other wells, to the Baseline Feeder. The Baseline Feeder is owned by the San Bernardino Valley Municipal Water District. The SBMWD has been anticipating additional water exchanges with San Bernardino Valley Municipal Water District via the Baseline Feeder to gain lower groundwater levels in the southern portion of the SBMWD.

h) Raw water transmission main: New raw water transmission mains have been installed to connect the extraction wells to the treatment plant. They include Ductile Iron Pipe (DIP) pipeline with diameters of 12 inches (1, 101 feet long), 16 inches (16,070 feet long), 20 inches (4, 114 feet long), 24 inches (15,058 feet long), and 30 inches (8,515 feet long). The mains have been constructed according to the Department guidelines.

3. The Source OU: The Source OU is being investigated by the USEPA. This unit has not been constructed.


Ill. APPRAISAL OF SANITARY HAZARDS AND SAFEGUARDS

The wells were drilled in accordance with acceptable water well construction techniques approved by the California Water Well Standards. Based upon location maps and information obtained from the Water Source Assessments and the operation plan, the wells are adequately located, and constructed. However, the Department will conduct a site inspection to verify the well features and the treatment design prior to the operation of the plant .

TCE and PCE is a major concern from water produced by these new wells. The expanded 191

h Street GAC treatment plant is capable to treat water produced by these wells to ensure the treated water meets the drinking water standards.

IV. CONCLUSION AND RECOMMENDATIONS
