EXECUTIVE SUMMARY 

The Department of the Navy, Naval Facilities Engineering Command, Pacific Division (NAVFAC 

PACIFIC) has retained Dawson Group, Inc. (DAWSON) to perfornt groundwater monitoring activities at 

the Red Hill Fuel Storage Facility (FSF), Hawaii. The Red Hill FSF consists of 20 active underground 

storage tanks (USTs) operated by the Fleet Industrial Supply Center (FISC) Pearl Harbor. Figure 1, Site 

V(cinity Map, illustrates the location of the project site. 

This work was performed under NAVFAC PACIFIC Contract Number N62742-01-D-1806, Contract 

Task Order (CTO) 0013. This document is the fourth quarterly report and summarizes the following: 

field investigation, IDW disposal, sample results, and conclusions and recommendations for the next 

sampling event. 

Site Background 

From 1998 to 2001, the Navy conducted an investigation at the facility to assess potential releases from 

the fuel storage facility. In February 2001, the Navy installed a one-inch diameter sentinel well (MWV I D) to monitor for contamination of the basa[ aquifer underlying the storage facility (AMEC Earth and 

Environmental, Inc. [AMEC], 2002). Sentinel well MW-V1D was installed and completed at 

approximately 100 feet below grade (fbg). At the time of well completion, depth to water in MW-V1D 

was measured at 86 fbg. The groundwater level at the project site fluctuates from dry season to wet 

season (AMEC, 2002). 

A second monitoring well (MW-V2S) was installed and completed above the water-bearing zone at 

approximately 52 tbg. This monitoring well is located southwest of sentinel well MW-V 1 D and does not 

contain either gmundwater or product. MW-V2S was intentionally completed above the water-bearing 

zone in order to avoid creation of a possible direct conduit to the basal aquifer (AMEC, 2002). 

In February 2001, groundwater samples collected from sentinel well MW-V1D contained tota[ petroleum 

hydrocarbon (TPH) concentrations ranging from 0.883 milligrams per liter (mg(L) to 1.05 mg/L and total 

lead ranging from 0.0104 mg/L to 0.015 mg/L. The maximum total lead concentration in the samples 

was equal to the primary drinking water standard of 0.015 mg/I. for lead and exceeded the State of 

Hawaii Department of Health (HDOH) Tier 1 groundwater action level (GWAL) of 0.0056 mg/L (US 

Navy, 2004). 

Following discussions with HDOH, a progtam was initiated to monitor the sentinel well MW-VID and 

the Navy Public Works Center (PWC) potable water stilling basin for indications of contamination from 

the upgradient tank fattn. The recommended parameters for analyses were TPH as diesel; TPH as 

gasoline; benzene, toluene, ethylbenzene, and total xylenes (BTEX); 1,2-dichloroethane (DCA); 

polynuclear aromatic hydrocarbons (PAHs); total lead; and 1,2-dibromoethane (EDB) (US Navy, 2004). 

Field Activities 

On December 6 and 7, 2005, three surface water samples (two primary and one duplicate) were collected 

from the PWC potable water stilling basin and analyzed for TPH as diesel, TPH as gasoline, 1,2-DCA, 

BTEX, methyl-tert-butyl ether (MtBE), total lead, and EDB. 

On 6 December 2005, two groundwater samples (one primary and one duplicate) were collected from the 

sentinel well, MW-V 1D and analyzed for TPH-D, TPH-G, 1,2-DCA, BTEX, total lead, and EDB.

Conclusions and Recommendations 

The following conclusions are based on the data collected during this investigation. 

Stiilina Basin 

Concentrations of dissolved lead, naphthalene, 2-methylnaphthalene were detected above 

the Iaboratory MRLs. No constituents were detected at concentrations above the HDOH 

Tier 1 G WALs or HDOH drinking water standard. 

Sentinel Wel! 

Concentrations of TPH as diesel, naphthalene, 2-methylnaphthalene, acenaphthene, 

dibenzofuran, fluorene, phenanthrene, fluoranthene, pyrene, benz(a)anthracene, chrysene, 

Benzo(a)pyrene and Benzo(g,h,i)perylene were detected above laboratory MRLs. No 

constituents were detected at concentrations above the HDOH Tier 1 GWALs. 

Dissolved lead was detected at concentrations above the laboratory MRL. The 

concentrations were below both the HDOH Tier 1 GWAL and the HDOH drinking water 

standard in the sentinel well samples. The December 2005 results were also less than the 

corresponding 2001 investigation results (AMEC, 2002). In both this quarter and the third 

quarter 2005, samples collected at MW-V1D contained lead concentrations below the 

HDOH Tier 1 GWAL and HDOH drinking water standard. It should be noted that in the 

first and second quarter 2005, samples collected from MW-V1D were not filtered prior to 

lead analysis. However in the last two quarters (third and fourth quarter 2005) samples 

were filtered prior to lead analysis. 

The groundwater in the upgradient sentinel well (MW-VID) shows evidence of 

contamination in the basal aquifer by contaminants of potential concern. 

Based on the findings during this investigation, DAWSON recommends the following actions: 

Installation of a dedicated pump within MW-V1D to avoid cross-contamination, to 

facilitate low-flow sampling methodology, to more efficiently sample the monitoring well, 

and to contribute to the repeatability of sampling methods. 

• Continue to filter lead samples during collection and prior to analysis. 

Continue sampling at the stilling basin and the sentinel well during the next quarter 

(January through March 2006).

1.3 Site Location and Facility Description 

The Red Hill FSF project site is located in Halawa Heights on Oahu, Hawaii. Access is via Halawa 

Valley Road, located north of the project site. Primary highways in the vicinity of the project site are 

Interstate Highways H-1 and H-3. Land adjacent to the north of the project site is occupied by 

Halawa High and Medium Security Facility and private businesses. Land to the south and west of 

the project site includes the Coast Guard Reservation. Moanalua Valley is located east of the facility 

(Figure 1, Sfte VicinftyMap). 

The Red Hill FSF consists of 20 active USTs operated by Navy FISC Pearl Harbor. Each UST has a 

capacity of 12.5 million gallons. The facility is located approximately 100 feet above the basal 

aquifer. Approximately 1,550 feet hydraulically downgradient from the tank farm, the Navy PWC 

operates a potable water infiltration tunnel (Figure 2, Sfte Plan). 

7.4 Previous Environmental Actions/Studies 

From 1998 to 2001, the Navy conducted an investigation at the facility to assess potential releases 

from the fuel storage facility. In February 2001, the Navy installed a one-inch diameter sentinel well 

(MW-V1D) to monitor for contamination of the basal aquifer underlying the storage facility (AMEC 

Earth and Environmental, Inc. [AMEC], 2002). Sentlnel well MW-VID was installed and 

completed at approximately 100 feet below grade (fbg). At the time of well completion, depth to 

water in MW-V 1 D was measured at 86 fbg. The groundwater at the project site fluctuates from dry 

season to wet season (AMEC, 2002). 

A second monitoring well (MW-V2S) was installed and completed above the water-bearing zone at 

approximately 52 fbg. This monitoring well is located southwest of sentinel well MW-V1D and 

does not contain either groundwater or product. MW-V2S was intentionally completed above the 

water-bearing zone in order to avoid creation of a possible direct conduit to the basal aquifer 

(AMEC, 2002). 

In Febnlary 2001, groundwater samples collected from sentinel well MW-VID contained TPH 

concentrations ranging from 0.883 milligrams per liter (mg(L) to 1.05 mg/[, and total lead ranging 

from 0.0104 mg/L to 0.015 mg/L. The maximum total lead concentration in the samples was equal 

to the primary drinking water standard of 0.015 mg/L for lead and exceeded the State of Hawaii 

Department of Health (HDOH) Tier 1 groundwater action level (GWAL) of 0.0056 mg/L (US Navy, 

2004). 

Following discussions with HDOH, a program was initiated to monitor the sentinel well MW-V1D 

and the PWC potable water stilling basin for indications of contamination from the upgradient tank 

farm. The recommended parameters for analyses were TPH; BTEX; 1,2 DCA; PAHs; total lead; and 

EDB (US Navy, 2004).

NAVFAC PACIFIC Red Hi114Q05 GW 

Contract No.: N62742-01-D-1806, CTO 0013 Page 2-1 

2. DATA QUALITY OBJECTIVES 

Environmental data are needed to: 1) determine if groundwater contamination is present at the project 

site; 2) determine the best course of action; and 3) characterize IDW wastewater for disposal. 

Chemical data must be of sufficient quality and quantity to confinn the presence or absence of 

contaminants of potential concern (COPC) in the groundwater beneath the Red Hill FSF. The COPCs for 

this investigation include TPH as diesel and as gasoline; BTEX; MtBE; 1,2 DCA; total lead; and EDB. 

The data qualiry objectives were designed to comply with the HDOH's Technical Gufdance Manual for 

Underground Storage Tank Closure and Release Response, Second Edition (HDOH, 2000) and RfskBased Corrective Action and Decision Making at Sites With Contaminated Soil and Groundwater, 

Yolume I and 11 (HDOH, 1996). 

The screening levels for this investigation will draw on the HDOH Tier 1 GWALs for sites receiving less 

than 200 centimeters of rainfall per year and threatening a drinking water source (HDOH, 2000). 

For reference purposes, the HDOH Environmental Action Levels (EALs) for sites greater than 150 meters 

from a surface water body where groundwater is a current or potenfial source of drinking water (HDOH, 

2005) have been included. However, it should be noted that the 2000 Tier I GWALs are the governing 

guidelines for the site as required by the HDOH's UST regulations. 

To evaluate the absence or presence of contaminants, the following quality criteria will be followed: 

1)Laboratory analytical methods will provide reporting limits that are lower than regulatory action levels, 

2) Chemical analyses of COPC will be performed using EPA publication SW-846, Test Methods for 

Evaluating Solid Waste, Physical/Chemical Methods, Third Edition methodology (EPA, 1998), and 

3) Laboratory chemical data will be used to assess each analyte's concentration exceeding HDOH Tier 1 

GWALs.

3. METHODOLOGIES AND PROCEDURES 

3.1 Equipment Decontamination 

All water-level measuring and water sampling equipment was decontaminated at the start and end of 

the project, as well as between locations, to reduce the possibility of cross-contamination. The 

equipment was first washed in potable water and non-phosphate detergent. Then it was rinsed in 

potable water, rinsed in deionized/distilled water, sprayed with isopropyl alcohol, and rinsed with 

deionized/distilled water. Decontamination washwater was placed in a Department of 

Transportation (DOT)-approved, steel, 30-gallon dnun and handled appropriately as described in 

detail in Section 5.3, Irrvestigatfon Derfved 6f'aste. 

3.2 Laboratory Analysis 

The laboratory used standard analytical methods as outlined in the EPA's publication SW846— Test 

Methods for Evaluating Solfd Waste, Third Editfon (EPA, 1998). The laboratory followed the EPA's 

method-specific quality control procedures as outline in SW846. 

The groundwater samples collected from the stilling basin and the sentinel well were analyzed by 

Columbia Analytical Services for the following parameters: 

• TPH as Diesel and TPH as Gasoline using EPA Method 8015M; 

• BTEX, 1,2-DCA, and MtBE using EPA Method 8260B; 

• EDB using EPA Method 504.1; 

• PAHs using EPA Method 8270C SIM/PAHs; and 

• Total Lead by EPA Method 6020. 

The analytical methods were requested by the NAVFAC PACIFIC in the Statement of Work (SOW) 

(U.S. Navy, 2004) and are industry standards. Site investigation activities were conducted in 

accordance with the R'P/FSP (DAWSON, 2005b) and the Project Procedures Manval, U.S. Navy 

PACDIV Installation Restoration Program (IRP) (PACDIV, 1998). Copies of laboratory reports and 

chain-of-custody records for groundwater samples are included in Appendix B, Laboratory Reports 

and Chafn-of Custody Records for Prfmary and QC Groundwater and Stilling Basin Samples. 

3.3 Stilling Basin Sampling Methodology 

Previously when sampling the stilling basin, no entry was permitted due to the characteristics of the 

stilling basin, which identified it as a permit-required confined space. Prior to this event, samples at 

the stilling basin were collected by lowering a sampling system which was a combination of a 

polyvinyl chloride (PVC) casing and a disposable bailer, where the bailer was inserted inside the 

PVC casing, and an IP probe was attached to the outside of the PVC casing. Together, the assembly 

was lowered to approximately six inches above the water surface, and then the bailer was lowered 

into the water to collect a sample. Once full, the bailer was raised into the PVC casing and the 

assembly was raised up through the entrance hatch, where the sample bottles were filled.

Contract No.. N62742-01-D-1806, CTO 0013 Page 3-2 

3.3.1 lnstallation of Temporary Well Conduit 

On 28 June 2005, a temporary well conduit was installed at the PWC potable water stilling 

basin to increase the repeatability of sample collection, and to allow more efficient sampling of 

the groundwater. In order to install this conduit, entry into the stilling basin was allowed. A 

confined space entry permit was completed (Appendix C), the air within the stilling basin area 

was monitored (for combustible gases, oxygen, carbon dioxide, and methane), and a safety 

retrieval line with tripod and fall protection harness was used by the entrant. Each section ofthe 

conduit was lowered by rope to the entrant from the entrance hatch. 

The bottom of the conduit was comprised of a 4-inch PVC end cap and 25 feet (5-foot sections) 

of factory-slotted (0.010), 2-inch diameter, schedule-40 polyvinyl chloride (PVC) screen. The 

sections, once lowered, were assembled by the entrant at the catwalk and secured to the outer 

side of the base of the ladder cage with heavy duty cable ties. The bottom of the screened 

interval was installed to be flush with the bottom of the PWC stilling basin. According to 

measurements taken from the catwalk, the screen was set in 23.1 feet of water. 

Attached to the top of the screened PVC section was approximately 60 feet of 2-inch diameter, 

schedule-40 PVC (10-foot sections) casing. The sections were lowered to the entrant who 

attached them to the already-in-place sections of screen. Every 5 feet, the conduit was secured 

to the outer side of the ladder cage with heavy duty cable ties. The top of the conduit was 

secured with a monitoring well compression cap. 

Once the conduit installation was completed, the safety retrieval line with tripod and fall 

protection hamess was disassembled. The conduit was installed at a height so that future entry 

into the stilling basin can be avoided. 

3.3.2 Surface Water Sampling Methodology 

Access to the stilling basin requires opening an entrance hatch (approximately 24 inches in 

diameter). A lockout/tagout procedure was used to prevent accidental closure. From the open 

entrance hatch, the depth-to-water to the nearest 0.01 foot was measured using an interface 

probe (IP) through the well conduit. The measurement and time were recorded on the Surface 

Water Field Sampling Log (Appendix D, Monftoring Well Samplfng Forms). 

The samples were then collected using a new weighted, disposable, single-check valve bailer 

that remained sealed in plastic (by the manufacturer) until use. The bailer was equipped with a 

bottom-discharging device. The bailer was lowered to the water surface through the well 

conduit and the bottom was submerged in the surface water. Once full, the bailer was raised 

through the well conduit and through the entrance hatch, where the samples bottles were filled. 

This procedure was repeated until all required primary and field duplicate (QC) samples were 

collected. 

3.3.3 Fie/d Quality Contro/ Sampling 

Surface water field duplicate (QC) samples were collected once per sampling event, following 

the sample collection procedures listed in Section 6.2.2, Surface Water Sampling Methodology. 

A laboratory-supplied trip blank was placed in the sample cooler containing the VOC samples 

to be shipped to the laboratory.

NAVFAC PACIFIC Red Hi114Q05 GW 

Contract No.: N62742-01-13-1806, CTO 0013 Page 3-3 

A temperature blank was placed in one sample cooler per shipment to be shipped to the 

laboratory. 

3.4 Sentinel Well Sampling Methodology 

This section describes the sampling methodology employed to collect groundwater samples. 

3.4.1 Measurement of Static Water Leve/ and Oetection of an lmmiscib/e Phase 

Before sampling, the depth to standing water, depth to an immiscible layer (if any), and the total 

depth of the well were measured to the nearest 0.01 foot using an IP to provide baseline data. 

The data were recorded on the Monitoring Well Field Sampling Log (Appendix B). 

In accordance with the SOW, if an immiscible phase is detected with the IP, the Project 

Manager and the Navy RPM/[YTR are to be notified immediately. No groundwater sample is 

collected unless otherwise directed by the Project Manager and/or Navy RPM/NTR. 

If no immiscible phase is detected with the IP, the measurements of depth to water and total 

depth of the well are used to calculate the volume of water in the well and the amount of water 

to be purged, as well as provide inforrnation on the integrity of the well (e.g., identification of 

siltation problems). 

3.4.2 Well Purging Methodology 

Purging was accomplished by removing goundwater from the well using a dedicated bailer 

approximately 12 feet in [ength and 0.5 inch in diameter attached to a new, dedicated rope. The 

bailer was [owered into the well with as little disturbance of the water as possible to minimize 

aeration of the water in the well. Once the bailer was full, it was slowly brought out of the 

water and the water was transferred to a clean container for evaluation of field parameters. The 

purge water was evaluated on a regular basis during purging and analyzed in the field for 

temperature, pH, specific conductivity, salinity, dissolved oxygen, redox potential, and turbidity 

using a YSI® water quality meter. At least four readings were taken during the purging 

process. The purging procedure was repeated until the calculated purge volume was removed 

or when three consecutive field pazameter measurements had stabilized to within approximately 

IO pereent. All informafion wa.s recorded on the Monitoring Well Fie[d Sampling Log 

(Appendix B). The purge water was placed in the 30-gallon, steel drum located onsite. 

3.4.3 Sample Collection Procedures 

The sentinel well was sampled when grotmdwater within it was representative of aquifer 

conditions and after it had recovered sufficiently to provide enough volume for the groundwater 

sample. A period of no more than two hours elapsed between purging and sampling to prevent 

groundwater interaction with the casing and atmosphere. Depth to water was measured and 

recorded prior to sampling to demonstrate the degree of recovery of the well. 

The bailer was lowered as described in Section 3.4.2, and once the bailer was full, it was 

brought out of the water and the water transferred directly into the laboratory-supplied 

containers. This procedure was repeated until all required primary and field duplicate (QC) 

samples were collected.

3.4.4 Fie/d Quality Contro! Sampling 

Groundwater field duplicate (QC) samples were collected once per sampling event, following 

the sample collection procedures listed in Section 3.4.3, Smnple Collection Procedures. 

A laboratory supplied trip blank was placed in the sample cooler containing the VOC samples 

to be shipped to the laboratory. 

A temperature blank was placed in one sample cooler per shipment to be shipped to the 

laboratory. 

3.5 Storage of Investigation Derived Waste 

IDW generated during this investigation included monitoring well purge water and decontamination 

wastewater totally less than 5 gallons. Wastewater was stored in a 30-gallon, DOT-approved, steel 

dnun. The dnun was taken to an offsite recycling facility on 8 February 2006. The non-hazardous 

waste manifest is included in Appendix A of this report.

4. INVESTIGATION RESULTS 

4.1 Stilling Basin Water Sample Results 

Three surface water samples (two primary and one duplicate) were collected from the PWC potable 

water stilling basin and analyzed for TPH-D, TPH-G, 1,2-DCA, BTEX, MtBE, dissolved Lead, and 

EDB on December 6 and 7 2005. The results are presented in Table 1, Summary of Groundwater 

Sample Results of this report. The laboratory analytical reports are presented in Appendix A, 

Laboratory Reports and Chain-of-Custody Records for Prima?y and QC Groundwater and Stilling 

Basin Samples. 

4.1.1 Disso/ved Lead 

Lead samples were collected in the field with a bailer and transferred to unpreserved sample 

bottles. Those sample bottles were brought to the Dawson office and filtered with a 0.45-micron 

filter into preserved sample bottles using a peristaltic pump and new polyethylene tubing. Lead 

was detected above the laboratory method reporting limits (MRLs) at concentrations ranging 

from 0.00002 mg/L to 0.00014 mg/L (Table 1). These concentrations were below the HDOH 

GWAL of 0.0056 mg/L (HDOH, 2000) and the HDOH drinking water standard of 0.015 mg/L 

(HDOH, 2002). 

4.1.2 Tota! Petroleum Hydrocarbons (TPH) 

TPH as diesel was not detected above the laboratory MRLs in the any of the stilling basin 

samples(Table 1).

4.2 Sentinel Well Groundwater Sample Results 

Two groundwater samples (one primary and one duplicate) were collected from the sentinel well, 

MW-VID and analyzed for TPH-D, TPH-G, 1,2-DCA, BTEX, MtBE, dissolved Lead, and EDB on 

6 December 2005. The results are presented in Table 2, Summary of Groundwater Sample Results, 

MW-Vl D, of this report. The laboratory analytical reports are presented in Appendix A. 

4.2.1 Dissolved Lead 

Lead samples were collected in the field with a bailer and transferred to unpreserved sample 

bottles. Those sample bottles were brought to the Dawson office and filtered with a 0.45-micron 

filter into preserved sample bottles using a peristaltic pump and new polyethylene tubing. Lead 

was detected above the laboratory MRL at concentrations of 0.00006 mg/L and 0.00004 mg/L 

in the primary and duplicate samples, respectively (Table 2). Both of these results were below 

the HDOH GWAL of 0.0056 mg/L (HDOH, 2000) and below the HDOH drinking water 

standard of 0.015 mg/L (HDOH, 2002).

4.3 Trip Blank Analytical Results 

One trip blank sample was submitted and analyzed for VOCs by EPA Method 8260b. The results 

are presented in Table 3, Summary of Trip Blank Resutts. The laboratory analytical reports are 

presented in Appendix A. 

No VOCs were detected at concentrations above the laboratory MRLs in the trip blank sample. 

4.4 Data Quality Review 

4.4.1 Fteld Quality Assurance/Quality Contiol 

Quality Assurance/Qua[ity Control (QA/QC) checks employed during the collection of field 

data and sampling activities included the following: 

Collection of samples and field measurements by DAWSON. DAWSON personnel 

were familiar with EPA protocols concerning equipment decontamination, sample 

collection, sample and project documentation, and QA/QC procedures. 

Use of certified clean laboratory sample containers. 

Preservation of sample integrity by chilling samples in the field and maintaining 

proper temperature until receipt at the laboratory. 

4.4.2 Laboratory/Quality Contro/ Data Assessment 

As part of the QC of this project, the DAWSON completed a desktop review of the data 

packages received from Columbia Ana[ytical Services. The desktop review included a review 

of the hold times, reagent blanks, surrogate recoveries, sample duplicates, matrix spike/matrix 

spike duplicates recoveries, relative percent differences, blank spike recovery and reporting 

limits. DAWSON concluded that the laboratory analyses meet QC criteria and can be used for 

the intended purpose. The duplicate results were consistent with all primary sample results and 

thus valid and useable. 

Laboratorv Data Assessment 

Insufficient sample volume was received to perform a Matrix Spike Duplicate (MSD). A 

Laboratory Control Sample/ Duplicate Laboratory Control Sample (LCS/DLCS) was analyzed 

and reported in lieu of the MS/MSD for these samples. 

No anomalies associated with the analysis of these samples were observed.

Data Discreoancies 

The relative percent differences between the primary and duplicate sample concentrations are 

presented in Tables 1 and 2. While it appears that the relative percent differences between the 

primary and duplicate are large, the values are below the HDOH Tier 1 GWALs. There were 

no significant data discrepancies between the primary and duplicate sample results. Columbia 

Analytical Services performed analyses on both the primary and duplicate samples. 

4.5 IDW Disposal 

AII IDW generated during the December 2005 event were determined to be non-hazardous wastes 

and were taken to an offsite recycling facility on 8 February 2006 The Non-Hazardous Waste 

Manifest is presented in Appendix A of this report.

5. CONCLUSIONS AND RECOMMENDATIONS 

The following conclusions are based on the data collected during this investigation. 

Stitlinn Basin 

• Concentrrations of dissolved lead, naphthalene, 2-methylnaphthalene were detected above 

the laboratory MRLs. No constituents were detected at concentrations above the HDOH 

Tier I G WALs or HDOH drinking water standard. 

Sentinel Well 

Concentrations of TPH as diesel, naphtha[ene, 2-methylnaphthalene, acenaphthene, 

dibenzofuran, fluorene, phenanthrene, fluoranthene, pyrene, benz(a)anthracene, chrysene, 

Benzo(a)pyrene and Benzo(g,h,i)perylene were detected above laboratory MRLs. No 

constituents were detected at concentrations above the HDOH Tier I G WALs. 

Dissolved lead was detected at concentrations above the laboratory MRL. The 

concentrations were below both the HDOH Tier 1 GWAL and the HDOH drinking water 

standard in the sentinel well samples. The December 2005 results were also less than the 

corresponding 2001 investigation results (AMEC, 2002). In both this quarter and the third 

quarter 2005, samples co[lected at MW-VID contained lead concentrations below the 

HDOH Tier I GWAL and HDOH drinking water standard. It should be noted that in the 

fitst and second quarter 2005, samples collected from MW-V1D were not filtered prior to 

lead analysis. However in the last two quarters (third and fourth quarter 2005) samples 

were filtered prior to lead analysis. 

The groundwater in the upgradient sentinel well (MW-ViD) shows evidence of 

contamination in the basal aquifer by contaminants of potential coneem. 

Based on the findings during this investigation, DA WSON recommends the fo[[owing actions: 

Installation of a dedicated pump within MW-V1D to avoid cross-contamination, to 

facilitate low-flow sampling methodology, to more efficiently sample the monitoring well, 

and to contribute to the repeatability of sampling methods. 

Continue to filter lead samples during collection and prior to analysis. 

Continue sampling at the stilling basin and the sentinel well during the next quarter 

(January through March 2006).

CASE NARRATIVE 

AII analyses were performed consistem with the quality assurance progtam of Columbia Analytical Services, Inc. 

(CAS). This repott contains analytical results for samples designated for Tier II data deliverables. When appropriate to 

the method, method blank results have been reported with each analytical test Surrogate recoveries have been repomd 

for all applicable organic analyses. Additional quality control analyses reported herein include: I.aboratory Duplicate 

(DUP), Matrix/Duplicate Matrix Sptice (MSlDMS), and Laboratory Control Sample (LCS). 

Samole Receiot 

Six water samples were received for analysis at Columbia Analytical Services on 12/9l05. The samples were 

received in good condition and consistent with the accompanying chain of custody fonn. The samples were stored 

in a refrigerator at 4°C upon receipt at the laboratory. 

Dissolved Metals 

No anomalies associated with the analysis of these samples were observed. 

Diesel Ran¢e Oreanics bv EPA Method 8015B 

Relative Percent DiRerence (RPD) Exceptions: 

The RPD criterion for the replicate analysis of DRO in Batch QC sample K0506473-001 is not applicable because 

the analyte concentration was not significantly greater than the Method Reporting Limit (MRL). Analytical values 

derived from measurements close to the detection limit are not subject to the same accuracy and precision criteria as 

results derived from measurements higher on the calibration range for the method. 

Gasoline Ranee Oreanics bv EPA Method 8015B 

No anomalies associated with the analysis of these samples were observed. 

EPA Method 504.1 

No anomalies associated with the analysis of these samples were observed.

The upper control criterion was exceeded for the surrogates Fluorene-d10 and Fluoranthene-dl0 in Method Blank 

KWG0521180-3. No target analytes were detected above the MRL in the Method Blank. Since the apparent 

problem equates to a high bias, the data quality is not signi6cantly affected. No further corrective action was 

appropriate. 

The control crheria were exceeded for the sutrogates Fluorene-d10 and Fluoranthene-d10 in LCS KWG0521180-3 

and DLCS KWG05211804. The associated matrix spike recoveries of target compounds were in control, indicating 

the analysis was in control. The surrogate outlier is flagged accordingly. No funher corrective action was 

appropriate. 

Sample [Votes and Discussion 

Insufficient sample volume was received to perform a Matrix Spike Duplicate (MSD). A Laboratory Control 

Sample/Duplicate Laboratory Control Sample (LCS/DLCS) was analyzed and reported in lieu of the MS/M3D for 

these samples. 

No other anomalies associated with the analysis of these samples were observed.
