1.0 INTRODUCTION

This assessment report summarizes the soil and groundwater chemical analytical results obtained from

the Lincoln Avenue Car Wash site (herein designated as the “site”) located at 302 North 1st Street, Yakima,

Washington (see Vicinity Map, Figure 1). This assessment report has been prepared by GeoEngineers, Inc.

(GeoEngineers) for the Washington State Department of Ecology (Ecology) under Contract Number

C1100145.

Assessment actions included collecting soil samples from groundwater monitoring well borings and

initiating a quarterly groundwater-monitoring program following the monitoring well installation. This report

summarizes the soil assessment results and the first two quarters of groundwater monitoring results. Site

features and exploration locations are depicted in the Site Plan, Figure 2.

2.0 SITE DESCRIPTION AND BACKGROUND

The site is located at the intersection of North 1st Street Avenue South and East Lincoln Avenue in Yakima,

Washington. The site is owned by the City of Yakima (City) and currently operates as a fuel station for City

fleet vehicles. The existing fuel dispensers are located beneath a canopy (Figure 2). The site is paved with

either concrete (around the dispensers and covering the underground storage tanks [USTs]) or asphalt. No

vegetation or structures (except the dispenser canopy) are present on the site. Two monitoring wells (MW-5

and MW-6) from prior assessments remain near the center and northeast corner of the site, respectively.

The site was previously owned and operated as the Lincoln Avenue Carwash, which included both an

automated carwash and an UST supplied fuel dispenser system. Four USTs were present, including:

■ A 10,000-gallon UST containing regular leaded gasoline (identified as Tank #1);

■ A 10,000-gallon UST containing unleaded gasoline (Tank #2);

■ A 5,000-gallon UST containing unleaded gasoline (Tank #3); and

■ A 4,000-gallon UST containing unleaded gasoline (Tank #4). Tank #4 reportedly previously contained

diesel.

In late 1996 and early 1997, inventory records indicated between 300 (Sage Earth Sciences [Sage] 1997)

and 470 gallons (Clayton, 2001) of gasoline leaked from Tank #4. Because of the apparent leak, the owner

decided to remove and replace the UST fueling system. Sage conducted the UST closure assessment and

a limited remedial action. The four USTs were decommissioned, removed and assessed in March 1997.

About 1,035 cubic yards of soil was removed from the UST excavation and transported off site for disposal.

Gasoline-impacted groundwater was observed seeping into the excavation at about 17 to 19 feet below

ground surface (bgs); the gasoline-impacted seepage was not addressed at that time. The excavation was

backfilled with imported fill material.

Eighteen confirmation soil samples and two groundwater samples were collected during the assessment.

Petroleum hydrocarbons were not detected at concentrations greater than applicable Washington State

Model Toxics Control Act (MTCA) cleanup levels in the soil confirmation samples. However, a lens of

petroleum-stained soil was observed above the groundwater interface. Total lead was detected in both

groundwater samples at concentrations greater than MTCA Method A cleanup levels. Benzene, toluene,


ethylbenzene and total xylenes (BTEX), and gasoline-range petroleum hydrocarbons (GRPH) were detected

at concentrations exceeding MTCA Method A cleanup levels from the groundwater sample collected in the

western portion of the excavation.

In 2001, additional soil and groundwater assessment was conducted by Clayton Group Services (Clayton)

to evaluate the nature and extent of remaining soil and groundwater contamination. In May 2001, five

direct-push soil borings (B-1 through B-5) were advanced to depths ranging between 4 to 16 feet bgs. BTEX,

GRPH, methyl-tert-butyl-ether (MTBE), and lead were either not detected or detected at concentrations less

than MTCA Method cleanup levels. Four monitoring wells (MW-1 through MW-4) were installed in July 2001.

Contaminants of concern were not detected in soil samples collected from the monitoring well borings at

depths between 9 to 16 feet bgs. Benzene was detected in the initial groundwater sample collected from

MW-1 at a concentration greater than the MTCA cleanup level. Contaminants of concern were either not

detected or detected at concentrations less than MTCA Method A cleanup levels in groundwater samples

from the other three monitoring wells. Groundwater measurements indicated a gradient to the

north-northeast and depth to groundwater was measured at depths ranging between 13.37 to 14.07 feet

bgs.

Two additional monitoring wells (MW-5 and MW-6) were installed in March 2002 to further assess

groundwater conditions. Based on the previous groundwater gradient data, the two new monitoring wells

were installed in downgradient locations relative to the former UST locations. Soil samples collected from

the monitoring well borings did not contain contaminants of concern at concentrations greater than MTCA

cleanup levels. Benzene, MTBE and GRPH were detected during the March 2002 groundwater monitoring

event at concentrations greater than MTCA Method A cleanup levels. Lead concentrations exceeded MTCA

cleanup in the groundwater sample collected from MW-6. The elevated lead concentrations might have

been caused by elevated turbidity in the sample. Based on the groundwater depth measurements collected

during this event, the groundwater gradient was to the east (Clayton, 2002).

A groundwater report prepared by Shannon and Wilson, Inc. (S&W) summarized the groundwater

monitoring from the initial sample (July 2001) through May 2008. GRPH was detected in monitoring well

MW-1 at a concentration exceeding the MTCA cleanup level during eight of the 12 sampling events,

including the last three events (November 2007, February and May 2008). Benzene concentrations

exceeding MTCA cleanup levels were observed during four events, including the last two (February and May

2008). Diesel-range petroleum hydrocarbons (DRPH) were detected exceeding MTCA cleanup levels during

three sampling events in 2003 from monitoring well MW-1. S&W also reported that the groundwater

gradient varied from east to south-southeast.

Monitoring wells MW-1 through MW-4 were removed in 2011 during construction of the Lincoln Avenue

railroad underpass. The underpass structure reportedly extends below the groundwater and might have

affected the local gradient. Site features are presented in Figure 2.

3.0 SCOPE AND TASKS

Based on the historic assessments reviewed, additional investigation was required to evaluate data gaps

and better define the extent of contamination. Our general approach consisted of focused site assessment

activities, which included drilling soil borings and collecting soil samples, installing additional groundwater

monitoring wells and conducting quarterly groundwater monitoring from new and existing wells. These


activities were completed to define the nature and extent of possible contamination in soil and

groundwater.

The following tasks were identified in the provided scope of work.

■ Task 1 – Soil Sampling and Laboratory Analysis

■ Task 2 – Groundwater Monitoring Well Installation

■ Task 3 – Groundwater Sampling and Laboratory Analysis

■ Task 4 – Data Evaluation and Reporting

A detailed description of the activities performed for each task is provided below.

3.1. Task 1. Soil Sampling and Laboratory Analysis

This task included initial field activities and collecting soil samples from soil borings during separate

mobilizations. Specific scope items included:

1. Coordinating underground utility locating using the one-call system and a subcontracted private utility

locator, Utilities Plus, LLC (Utilities Plus).

2. Coordinating traffic control using StripeRite during the installation of MW-7.

3. Subcontracting Cascade Drilling (Cascade) to install two monitoring wells (MW-7 and MW-8) using sonic

drilling techniques. Borings were advanced to 25 feet bgs. Continuous soil samples were collected

and select sub-samples were field screened using water sheen techniques, a photoionization detector

and visual observations.

4. Submitting one soil sample from each boring to TestAmerica Laboratories Inc. (TestAmerica) for

chemical analysis. Chemical analyses were conducted using a combination of the following methods:

a. GRPH using Northwest Method NWTPH-Gx.

b. DRPH and oil-range petroleum hydrocarbons (ORPH) using Northwest Method NWTPH-Dx.

c. Lead using U.S. Environmental Protection Agency (EPA) Method 6010.

d. Volatile organic compounds (VOCs) using EPA Method 8260.

e. 1,2-dibromoethane (EDB) using EPA Method 8011.

f. Polycyclic aromatic hydrocarbons (PAHs) using EPA Method 8270.

5. Managing investigation-derived waste (IDW) generated during the investigation.

3.2. Task 2. Groundwater Monitoring Well Installation

This task included installing monitoring wells MW-7 and MW-8 to assess groundwater for contaminants of

concern and to evaluate groundwater flow direction. Generally, actions in this task included:

1. Constructing monitoring wells using 2-inch-diameter, Schedule 40 polyvinyl chloride (PVC) casing and

well screen material, with the top of the well screen located approximately 5 feet above the estimated


groundwater level, and total well screen lengths of 15 feet. The wells were completed with flush-mount

surface monuments.

2. Subcontracting PLS, Inc., a licensed surveyor, to survey the horizontal location and top of well casing

elevation. Elevation was measured to the nearest 0.01 foot relative to the North American Vertical

Datum of 1988 (NAVD88). The horizontal location was measured to within 0.1 foot to the North

American Vertical Datum of 1983, updated 1991 (NAD83 [91]). Survey locations on the PVC well

casing were marked by the surveyor on the north side of the casing.

3.3. Task 3. Groundwater Sampling and Laboratory Analysis

This task included conducting the first and second quarterly groundwater monitoring events for the existing

wells (MW-5 and MW-6) and the new wells (MW-7 and MW-8). Specific groundwater monitoring tasks

included:

1. Inspecting the well cap and monument integrity. Depth-to-water was measured in each well to calculate

the groundwater elevation.

2. Collecting groundwater samples using low-flow, low-stress sampling techniques. Groundwater quality

field parameters were measured during purging activities, including pH, temperature, conductivity,

dissolved oxygen (DO), oxidation-reduction potential (ORP) and turbidity. One duplicate sample was

collected per event.

3. Submitting groundwater samples to TestAmerica for the chemical analyses listed in Task 1. In addition

to DRPH analysis using NWTPH-Dx, groundwater samples collected during these events were analyzed

using NWTPH-Dx with silica gel cleanup, for comparison purposes, if DRPH were detected at

concentrations greater than the laboratory-reporting limit. Additionally, samples were analyzed for

natural attenuation parameters, including: nitrate, soluble manganese (Mn+2), sulfate (SO4), methane

(CH4) and alkalinity. Soluble ferrous iron (Fe+2), which has a 15-minute hold time, was analyzed in the

field using a Hach IR-18C color disc test kit and the 1,10 phenanthroline testing method.

4. Managing IDW and coordinating disposal after obtaining chemical analytical results.

3.4. Task 4. Data Evaluation and Reporting

Upon completion of field exploration activities and the groundwater sampling events, this assessment

report was provided summarizing the field activities, soil analytical results, the groundwater analytical

results, a comparison of analytical results to MTCA Method A cleanup levels, and an estimation of

groundwater flow direction and gradient.

4.0 FIELD ASSESSMENT

This section describes the field assessment procedures and observations. Assessment actions included:

■ Installing monitoring wells MW-7 and MW-8;

■ Collecting and submitting soil samples for chemical analysis; and

■ Conducting two quarterly groundwater-monitoring events.


4.1. Monitoring Well Installation

Prior to installing the monitoring wells the one-call utility notification was contacted to identify and mark

underground utilities. Additionally, Utilities Plus identified and marked underground utilities located near

the proposed monitoring well locations. Cascade drilled monitoring wells (MW-7 and MW-8) on

August 14, 2014 using sonic drilling methods and constructed the monitoring wells using 2-inch-diameter,

Schedule 40 PVC casing and 0.010-slotted well screen material, with the top of the well screen located

approximately 5 feet above the estimated groundwater level, and total well screen lengths of 15 feet. The

monitoring wells were drilled to about 25 feet bgs and were completed with flush-mount surface

monuments. Monitoring well MW-7 was installed at a downgradient location relative to historical USTs and

reported contamination. Monitoring well MW-8 was installed at an upgradient location relative to the

documented contamination.

PLS, Inc. surveyed the horizontal and vertical locations of the monitoring wells on August 26, 2014. The

PVC casing was surveyed relative to the north side of the casing. The top of casing elevation ranged

between 1,073.08 feet (MW-7) to 1,073.70 feet (MW-5). The casing elevations were surveyed relative to

the NAVD88 vertical datum and the horizontal locations were surveyed relative to the NAD83/91

Washington South Zone.

IDW, consisting of excess soil cuttings, and decontamination and development water generated from the

soil borings and monitoring wells, was drummed and stored near the northwest corner of the site. After

receiving the soil and groundwater chemical analytical results, Able Cleanup Technologies (Able) was

contracted to profile and dispose the accumulated IDW. Able transported IDW to Waste Management’s

Graham Road Landfill in November 2014.

4.2. Soil Sampling

Soil samples were collected from the monitoring well explorations for field screening and potential chemical

analysis. One soil sample was submitted from each monitoring well boring for chemical analysis from

depths ranging between 14 to 15 feet bgs, which represents the top of the shallow aquifer beneath the

site.

Subsurface Conditions

GeoEngineers field representative observed each monitoring well boring, classified the soil encountered,

and prepared a detailed log of each exploration. Soil encountered in the borings was classified in the field

in general accordance with ASTM International (ASTM) D 2488, the Standard Practice for Classification of

Soils, Visual-Manual Procedure. Soil conditions observed from the explorations generally consisted of

gravel with varying quantities of silt, sand and cobbles. Groundwater was encountered in the soil borings

at about 14½ to 15 feet bgs. Soil boring logs are included in Appendix A.

Field Screening Observations

Soil sub-samples from each soil boring were field-screened for the presence of petroleum-related

compounds using the procedures described in Appendix A. Water sheens were not observed from the soil

removed from the monitoring well borings. Headspace vapors were detected from the borings at

concentrations ranging up to 93.9 parts per million (ppm). Headspace vapors detected from the soil

borings were likely caused by high daily temperatures (greater than 90 degrees Fahrenheit) and additional

excess heat generated by the sonic drill rig pulverizing subsurface cobbles causing interference with the


photoionization detector (PID) readings. Field screening results are recorded on the boring logs included

in Appendix A.

4.3. Quarterly Groundwater Monitoring

A groundwater-monitoring program was initiated following construction of the monitoring wells. The first

groundwater-sampling event was conducted on September 17, 2014. A sufficient number of sample

containers were not requested and filled during the September 17, 2014 event to conduct the proposed

chemical analyses. Only DRPH, ORPH, lead and the natural attenuation parameters were analyzed during

this event. A subsequent groundwater-monitoring event was conducted on October 13, 2014 to obtain the

desired chemical analytical results. Subsequent groundwater sampling events will be conducted quarterly

for up to three additional quarters. The groundwater-monitoring program includes both the existing

monitoring wells (MW-5 and MW-6) and the two recently installed wells (MW-7 and MW-8). Groundwater

sampling procedures are described in Appendix A.

Monitoring Well Headspace Vapor Monitoring

GeoEngineers measured monitoring well headspace vapors using a PID. Headspace measurements were

collected by inserting the PID probe into the well casing immediately after removing the well cap and

recording the maximum observed concentration. Headspace vapor concentrations were 0.0 to 0.1 ppm on

September 17 and were 0.0 to 1.2 ppm on October 13, 2014. Results are presented in Summary of

Groundwater Level Measurements, Table 1.

Groundwater Elevation Measurement

GeoEngineers measured the static depth to groundwater using an electronic water-level indicator. Depths

ranged from 14.35 feet (MW-6) to 15.10 feet (MW-5) below the top of well casing on September 17, 2014,

corresponding to groundwater elevations ranging between 1,059.25 feet in MW-6 to 1,058.60 feet in

MW-5. Depth to groundwater ranged between 14.68 feet (MW-6) and 15.41 feet (MW-5) below the top of

well casing on October 13, 2014, corresponding to elevations ranging between 1,058.92 feet in MW-6 and

1,058.29 feet in MW-5.

Based on groundwater elevations measured during both the September and October 2014 events,

groundwater contours were generated using Surfer®12 groundwater modeling software. Shallow

groundwater flow direction beneath the site generally was toward the east-southeast. The average

hydraulic gradient was about 0.01 feet per foot (about 50 feet per mile) during both the September and

October events. Groundwater elevations in the shallow unconfined aquifer underlying the site are

influenced by the rate of groundwater recharge (infiltration of precipitation and snowmelt) within associated

upland areas to the north, west and south of the site, and potentially, the stage of adjacent surface water

within local irrigation canals and the Yakima River. Groundwater depths and associated groundwater

elevations are included in Table 1. Groundwater Contour Map, September 17, 2014, Figure 3 presents

groundwater elevations, approximate groundwater elevation contours and interpreted groundwater flow

direction on September 17, 2014. Groundwater Contour Map, October 13, 2014, Figure 4, depicts the

groundwater elevations, approximate groundwater elevation contours and interpreted groundwater flow

direction on October 13, 2014.


Groundwater Sampling

GeoEngineers purged and sampled project monitoring wells on September 17, 2014 and October 13, 2014

in general compliance with standard low-flow sampling methodology. A portable peristaltic pump equipped

with disposable tubing was used to purge and sample each well. Groundwater water quality parameters

generally were measured at approximate 3-minute intervals during well purging. Groundwater samples

were collected when each water quality parameter had stabilized in conformance with the criteria

presented in Appendix A, or the maximum purge time had been achieved. Stabilization of water quality

parameters was achieved between 15 and 18 minutes during the September 2014 groundwater-sampling

event and between 15 and 24 minutes during the October 2014 groundwater-sampling event. A duplicate

groundwater sample was collected during each event from monitoring well MW-8.

Purge water generated during groundwater sampling was drummed, labeled and stored near the northwest

corner of the site pending analytical results for profiling and disposal.

5.0 CHEMICAL ANALYTICAL RESULTS

Soil and groundwater chemical analytical results are summarized in Summary of Chemical Analytical

Results – Soil, Table 3 and Summary of Chemical Analytical Results – Groundwater, Table 4. Laboratory

reports are included in Appendix B.

5.1. Soil Sample Results

Two soil samples (plus one duplicate sample) were submitted for analysis from the monitoring well borings.

Soil samples were analyzed for the following potential contaminants of concern: GRPH, ORPH, DRPH, VOCs,

EDB, PAHs, and lead using the analytical methods described in “Section 3.0.” Potential contaminants of

concern were either not detected or detected at concentrations less than their respective MTCA Method A

Cleanup levels.

5.2. Groundwater Chemical Analytical Results

September 17, 2014

Four groundwater samples (plus one duplicate sample) from the September 17, 2014 groundwater-

monitoring event were analyzed for following: ORPH, DRPH, lead and natural attenuation parameters using

the analytical methods described in “Section 3.0.” DRPH, ORPH and lead were either not detected or were

detected at concentrations less than Method A CULs.

October 13, 2014

Four groundwater samples (plus one duplicate sample) from the October 13, 2014 groundwater-monitoring

event were analyzed for the following: GRPH, ORPH, DRPH, VOCs, EDB, PAHs, lead, and natural attenuation

parameters using the analytical methods described in “Section 3.0.” The potential contaminants analyzed

were not detected in the groundwater samples.

5.3. Groundwater Natural Attenuation Parameters

In addition to the contaminants of concern, groundwater samples from the September 2014 event and the

October 2014 event were analyzed for natural attenuation parameters. Chemical analytical results are


tabulated and compared to MTCA Method A cleanup levels in Table 4. Copies of original laboratory reports

are provided in Appendix B.

DO, temperature, specific conductivity, pH and ORP were measured in the field using a Troll 9500 multi-

parameter meter equipped with a flow-through cell. Reported field parameters reflect stabilized conditions

at the conclusion of well purging during low-flow sampling. Ferrous iron (Fe+2) concentrations also were

measured in the field using a Hach IRC-18C color disc test kit and the 1,10 phenanthroline testing method.

Field measurement results are provided in Summary of Field-Measured Natural Attenuation Parameters,

Table 2. Field and laboratory analytical results for natural attenuation parameters are summarized by the

following:

■ Soluble manganese was detected in MW-8 during the September 2014 sampling event and MW-6

during the October 2014 sampling event at a concentration of 0.0276 and 0.0935 milligrams per liter

(mg/L), respectively, which is less than the MTCA Method B standard formula cleanup level

(2.24 mg/L). The manganese detection from MW-6 did exceed the secondary maximum contaminant

level (SMCL, 0.05 mg/L) established by the EPA.

■ Methane was not detected.

■ Nitrate-Nitrogen was detected in the monitoring wells at concentrations ranging from 2.65 to 3.03 mg/L

during the September event and 2.78 to 2.85 mg/L during the October event. The detected

concentrations were less than the Maximum Contaminant Level (MCL) recommended by the EPA

(10 mg/L).

■ Sulfate was detected in the monitoring wells at concentrations ranging from 10.9 to 11.6 mg/L during

the September event and 11.0 to 11.5 mg/L during the October event. The detected concentrations

were less than the SMCL recommended by the EPA (250 mg/L).

■ Total alkalinity was detected in all monitoring wells at concentrations ranging from 75.0 to 85.0 mg/L

during both monitoring events.

■ DO ranged from 4.95 mg/L in MW-7 to 7.43 mg/L in MW-6 during September 2014 and from

5.69 mg/L in MW-7 to 7.09 mg/L in MW-5 during October 2014.

■ Temperature ranged from 16.30 degrees Celsius in MW-8 to 17.85 degrees Celsius in MW-7 during

the September 2014 event and from 16.53 degrees Celsius in MW-8 to 17.96 degrees Celsius in MW-5

during the October 2014 event.

■ Specific conductivity ranged from 0.2081 milliSiemens per centimeter (mS/cm) in MW-8 to

0.2207 mS/cm in MW-5 during September 2014 and from 0.2145 mS/cm in MW-8 to 0.2259 mS/cm

in MW-7 during October 2014.

■ pH ranged from 6.39 in MW-7 to 6.61 in MW-8 during September 2014 and from 6.52 in MW-7 to

6.66 in MW-5 during October 2014.

■ Normalized ORP (relative to the standard hydrogen electrode) ranged from 429 millivolts (mV) in MW-5

to 689 mV in MW-8 during September 2014 and from 433 mV in MW-5 to 600 mV in MW-6 during

October 2014.

■ Soluble ferrous iron concentrations were not detected.


Biodegradation does not appear to be occurring in shallow groundwater beneath the site. Natural

attenuation parameters were relatively unchanged between upgradient and downgradient monitoring wells.

Additionally, DO measurements during both events were relatively high compared to other sites where

aerobic degradation is occurring. Based on these measurements, it is unlikely petroleum-related

contaminants are present in shallow groundwater beneath the site.

6.0 SUMMARY, CONCLUSIONS AND RECOMMENDATIONS

Soil assessment activities were conducted August 13, 2014 at the Lincoln Avenue Car Wash site located

at 302 North 1st Street, Yakima, Washington. Two soil borings were advanced to depths of about 25 feet.

The borings were completed as groundwater monitoring wells (MW-7 and MW-8). Observed soil conditions

generally consisted of gravel with varying quantities of silt, sand and cobbles. Groundwater was

encountered during drilling at depths of about 14½ to 15 feet. No field screening indications of

contamination were observed except headspace vapors (likely caused by high ambient temperatures and

friction heat from the sonic drilling method). Contaminants of concern were either not detected or detected

at concentrations less than MTCA Method A cleanup levels in soil samples collected from the monitoring

well borings.

Groundwater samples were collected from wells MW-5 through MW-8 on September 17, 2014 and on

October 13, 2014. Depth to groundwater ranged from 14.35 feet (MW-6) to 15.10 feet (MW-5) below the

top of well casing on September 17, 2014 and depth to groundwater ranged between 14.68 feet (MW-6)

and 15.41 feet (MW-5) below the top of well casing on October 13, 2014. Contaminants of potential

concern were either not detected or detected at concentrations less than MTCA Method A cleanups levels

in the groundwater samples collected during both events.

The natural attenuation parameter measurements and results suggest that aerobic degradation is not

occurring in site monitoring wells. We recommend continuing the quarterly groundwater monitoring an

additional three events. These events include an additional groundwater monitoring event in the 4th Quarter

of 2014 so that four events analyzing the chemicals needed to obtain a no further action designation will

be conducted before the close of the current biennium. If contaminants are not detected during future

groundwater monitoring events, then we recommend no further action.

APPENDIX A

FIELD METHODS AND BORING LOGS

General Soil Sampling Procedures

Samples were obtained using disposable nitrile gloves, which were discarded after each use. Samples

were placed in 4 or 9-ounce laboratory-supplied sample containers. Sample containers were filled to

minimize headspace and labeled with a unique identification. Confirmation samples analyzed for VOCs

were obtained using EPA Method 5035 sampling procedures. Samples were temporarily stored in an iced

cooler before transfer to TestAmerica’s Spokane Valley, Washington laboratory for analysis. Chain-of-

custody protocols were followed.

Field Screening of Soil Samples

A GeoEngineers representative performed field screening of soil samples obtained during drilling activities.

Field screening results are used as a general guideline to delineate depths with possible petroleum-related

contamination. The screening methods used include: (1) visual screening; (2) water sheen screening; and

(3) headspace vapor screening using a MiniRae PID calibrated to isobutylene.

Visual screening consists of inspecting the soil for stains indicative of petroleum-related contamination.

Visual screening is generally more effective when contamination is related to heavy petroleum

hydrocarbons such as motor oil, or when hydrocarbon concentrations are high. Water sheen screening is

a more sensitive method that has been effective in evaluating whether contaminant concentrations are

less than regulatory cleanup guidelines.

Water sheen screening involves placing soil in water and observing the water surface for signs of sheen.

Sheen screening might detect both volatile and nonvolatile petroleum hydrocarbons. Sheen classifications

are as follows:

Headspace vapor screening involved placing a soil sample in a plastic sample bag. Air was captured in the

bag, and the bag was shaken to expose the soil to the air trapped in the bag. The probe of the PID was

then inserted into the bag to measure VOCs in the air within the bag. In this application, the PID measured

concentration of organic vapors ionizable by a 10.6 electron volt (ev) lamp in the range between 1.0 and

2,000 ppm, with a resolution of +/- 2 ppm.

Field screening results are site specific. The effectiveness of field screening results will vary with

temperature, moisture content, organic content, soil type, and type and age of contaminant. The presence

or absence of a sheen or headspace vapors does not necessarily indicate the presence or absence of

petroleum hydrocarbons.

No Sheen No visible sheen on water surface.

Slight Sheen Light, colorless, dull sheen; spread is irregular, not rapid; sheen dissipates rapidly.

Natural organic matter in the soil might produce a slight sheen.

Moderate Sheen Light to heavy sheen; might have some color/iridescence; spread is irregular to

flowing, might be rapid; few remaining areas of no sheen on water surface.

Heavy Sheen Heavy sheen with color/iridescence; spread is rapid; entire water surface might be

covered with sheen.


Monitoring Well Construction, Development and Surveying

The groundwater monitoring wells were constructed in general accordance with Chapter 173-160,

Section 400 of the Washington Administrative Code (WAC), titled Washington State Resource Protection

Well Construction Standards. Monitoring well records were submitted in accordance with Washington State

monitoring well construction standards. Monitoring well installations were observed and documented by a

GeoEngineers field representative.

The groundwater monitoring wells were installed using sonic drilling equipment and were constructed of

2-inch-diameter, Schedule 40 PVC casing and 0.01-inch slot width well screens. Well screen depths were

based on groundwater conditions observed in the field such that the top of the shallow water table

intercepted the well screen.

Each well was constructed with a bentonite seal and a flush-mount surface monument. A lockable cap was

installed in the top of the PVC well casing. A concrete surface seal was placed around the monument at

the ground surface to divert surface water away from the well location. Each well was developed using

surging and pumping; wells were surged and then pumped until the development water was clear. This

process was repeated until at least approximately five well volumes were removed from the well.

The monitoring well was developed to remove water introduced into the well during drilling (if any), stabilize

the filter pack and formation materials surrounding the well screen, and restore the hydraulic connection

between the well screen and the surrounding soil. The depth to water in the monitoring well was measured

prior to development. The total depth of the well was measured and recorded. The groundwater monitoring

wells were developed by pumping, surging, bailing, or a combination of these methods after construction.

Development of the well continued until the water was as free of sediment as practicable, with respect to

the composition of the subsurface materials within the screened interval. The removal rate and amount of

groundwater removed was recorded during the well development procedures. Development purge water

was collected and stored on site.

The locations of the groundwater monitoring wells were established in the field using a hand-held iPad with

global positioning system (GPS) software, and subsequently surveyed by a licensed surveyor.

Depth to Groundwater

Depth to groundwater measurements from the new wells were collected and recorded in the field notebook

after the water level stabilized after well development. Depth to groundwater relative to the marked north

side of the monitoring well casing rims was measured to the nearest 0.01 foot using an electronic water

level indicator and recorded in the field notebook. Groundwater elevation was calculated by subtracting

the depth-to-water measurement from the surveyed casing rim elevation. The electronic water level

indicator was decontaminated with Liquinox® solution wash and a distilled water rinse prior to use in each

well.

Groundwater Sampling

Following depth to groundwater measurements, groundwater samples were collected from the installed

groundwater monitoring wells consistent with the EPA’s low-flow groundwater sampling procedures

(EPA, 2010; Puls and Barcelona, 1996). Dedicated polyethylene tubing and a portable peristaltic pump

were used for groundwater purging and sampling. During purging activities, water quality parameters,


including pH, temperature, conductivity, DO, and turbidity were measured using a multi-parameter meter

equipped with a flow-through cell. Groundwater samples were collected after (1) water quality parameters

stabilized; or (2) a maximum purge time of 60 minutes was achieved. During purging and sampling,

drawdown was not allowed to exceed 0.3 feet and the purge rate did not exceed 400 milliliters per minute.

Water quality parameter stabilization criteria included the following:

■ Turbidity: ±10 percent for values greater than 5 nephelometric turbidity units;

■ Conductivity: ±3 percent;

■ pH: ±0.1 unit;

■ Temperature: ±3 percent; and

■ DO: ± 10 percent.

Field water quality measurements and depth-to-water measurements were recorded on a Well Purging-Field

Water Quality Measurement Form. The groundwater samples were transferred in the field to laboratory-

prepared sample containers and kept cool during transport to the testing laboratory. Chain-of-custody

procedures were observed from the time of sample collection to delivery to the testing laboratory consistent

with the Quality Assurance Project Plan (QAPP).

Location Control

The locations of the borings and groundwater monitoring wells were established in the field using a hand-

held iPad with GPS software. The horizontal accuracy of the hand-held unit is within about 10 feet. Upon

completion, horizontal and vertical locations of the groundwater monitoring wells were survey by a licensed

professional surveyor and referenced to NAD83 and NAVD88 respectively.

Decontamination Procedures

The objective of the decontamination procedure was to minimize the potential for cross contamination

between exploration locations and between individual samples within a specific exploration. A designated

decontamination area was established for decontamination of drilling equipment and reusable sampling

equipment. Drilling equipment was cleaned using pressure washing equipment.

Sampling or measurement equipment was decontaminated in accordance with the following procedures

before each sampling attempt or measurement:

■ Brush equipment with a wire brush, if necessary, to remove large particulate matter.

■ Rinse with potable tap water.

■ Wash with non-phosphate detergent solution (LiquiNox® and potable tap water).

■ Rinse with potable tap water.

■ Rinse with distilled water.

Handling of Investigation-Derived Waste (IDW)

IDW (drill cuttings and development and purge water), was placed in U.S. Department of Transportation

(DOT) approved 55-gallon drums. The drums were labeled with the exploration number, general contents,


and date. IDW generated on site was placed in drums and is pending pickup for disposal at an appropriate

facility.

Disposable items, such as sample tubing, direct-push sampler acrylic sleeves, gloves and paper towels,

etc., were placed in plastic bags after use and deposited in trash receptacles for disposal.

Laboratory Analytical Plan

Method reporting limit (MRL) goals were based on Ecology MTCA soil or groundwater cleanup criteria. The

following methods were used for the soil and groundwater samples:

Data Validation Report 523 East Second Avenue, Spokane, Washington 99202, Telephone: 509.363.3125, Fax: 509.363.3126 www.geoengineers.com

Project: Lincoln Avenue Car Wash 2014 Soil and Groundwater Samples

GEI File No: 00504-101-01

Date: December 22, 2014

This report documents the results of a United States Environmental Protection Agency (EPA)-defined Stage 2A data validation (EPA Document 540-R-08-005; EPA, 2009) of analytical data from the analyses of soil and groundwater samples collected as part of the 2014 sampling events, and the associated laboratory and field quality control (QC) samples. The samples were obtained from the Lincoln Avenue Car Wash Site located at 302 North 1st Street, Yakima, Washington.

Objective and Quality Control Elements

GeoEngineers, Inc. (GeoEngineers) completed the data validation consistent with the EPA Contract Laboratory Program National Functional Guidelines for Superfund Organic Methods Data Review (EPA, 2008) and Inorganic Superfund Data Review (EPA, 2010) (National Functional Guidelines) to determine if the laboratory analytical results meet the project objectives and are usable for their intended purpose. Data usability was assessed by determining if:

■ The samples were analyzed using well-defined and acceptable methods that provide reporting limits below applicable regulatory criteria;

■ The precision and accuracy of the data are well-defined and sufficient to provide defensible data; and

■ The quality assurance/quality control (QA/QC) procedures utilized by the laboratory meet acceptable industry practices and standards.

In accordance with Quality Assurance Project Plan (Appendix A of the Work Plan, Soil and Groundwater Assessment; GeoEngineers, 2014), the data validation included review of the following QC elements:

■ Data Package Completeness

■ Chain-of-Custody Documentation

■ Holding Times and Sample Preservation

■ Surrogate Recoveries

■ Method Blanks

■ Matrix Spikes/Matrix Spike Duplicates

■ Laboratory Control Samples/Laboratory Control Sample Duplicates

■ Laboratory and Field Duplicates

■ Methane by Method RSK-175.

Data Validation Summary

The results for each of the QC elements are summarized below.

Data Package Completeness

TestAmerica provided all required deliverables for the data validation according to the National Functional Guidelines. The laboratory appears to have followed adequate corrective action processes; however, with the exception of SDG SXJ0093, the laboratory analytical reports do not contain a case narrative.

Chain-of-Custody Documentation

Chain-of-custody (COC) forms were provided with the laboratory analytical reports. The COCs were accurate and complete when submitted to the laboratory.


File No. 00504-101-01

Holding Times and Sample Preservation

The sample holding time is defined as the time that elapses between sample collection and sample analysis. Maximum holding time criteria exist for each analysis to help ensure that the analyte concentrations found at the time of analysis reflect the concentration present at the time of sample collection. Established holding times were met for all analyses. The sample coolers arrived at the laboratory within the appropriate temperatures of between 2 and 6 degrees Celsius.

Surrogate Recoveries

A surrogate compound is a compound that is chemically similar to the organic analytes of interest, but unlikely to be found in any environmental sample. Surrogates are used for organic analyses and are added to all samples, standards, and blanks to serve as an accuracy and specificity check of each analysis. The surrogates are added to the samples at a known concentration and percent recoveries are calculated following analysis. All surrogate percent recoveries for field samples were within the laboratory control limits.

Method Blanks

Method blanks are analyzed to ensure that laboratory procedures and reagents do not introduce measurable concentrations of the analytes of interest. A method blank was analyzed with each batch of samples, at a frequency of one per 20 samples. For all sample batches, method blanks for all applicable methods were analyzed at the required frequency. None of the analytes of interest were detected above the reporting limits in any of the method blanks.

Matrix Spikes/Matrix Spike Duplicates

Since the actual analyte concentration in an environmental sample is not known, the accuracy of a particular analysis is usually inferred by performing a matrix spike (MS) analysis on one sample from the associated batch, known as the parent sample. One aliquot of the sample is analyzed in the normal manner and then a second aliquot of the sample is spiked with a known amount of analyte concentration and analyzed. From these analyses, a percent recovery is calculated. Matrix spike duplicate (MSD) analyses are generally performed for organic analyses as a precision check and analyzed in the same sequence as a matrix spike. Using the result values from the MS and MSD, the relative percent difference (RPD) is calculated. The percent recovery control limits for MS and MSD analyses are specified in the laboratory documents, as are the RPD control limits for MS/MSD sample sets.

For inorganic methods, the matrix spike is followed by a post-digestion spike sample if any element percent recoveries were outside the control limits in the matrix spike. The percent recovery control limits for matrix spikes are 75 to 125 percent.

One MS/MSD analysis should be performed for every analytical batch or every 20 field samples, whichever is more frequent. The frequency requirements were met for all analyses and the percent recovery and RPD values were within the proper control limits, with the following exception:

SDG SXH0105: (EDB) The laboratory performed an MS/MSD sample set with an RPD outlier; however, it was performed on a sample that was not associated with the samples in this SDG. For this reason, no action was required for this outlier.


File No. 00504-101-01

Laboratory Control Samples/Laboratory Control Sample Duplicates

A laboratory control sample (LCS) is a blank sample that is spiked with a known amount of analyte and then analyzed. An LCS is similar to an MS, but without the possibility of matrix interference. Given that matrix interference is not an issue, the LCS/LCSD control limits for accuracy and precision are usually more rigorous than for MS/MSD analyses. Additionally, data qualification based on LCS/LCSD analyses would apply to all samples in the associated batch, instead of just the parent sample. The percent recovery control limits for LCS and LCSD analyses are specified in the laboratory documents, as are the RPD control limits for LCS/LCSD sample sets.

One LCS/LCSD analysis should be performed for every analytical batch or every 20 field samples, whichever is more frequent. The frequency requirements were met for all analyses and the percent recovery and RPD values were within the proper control limits, with the following exception:

SDG SXH0105: (VOCs) The percent recovery for 1,1,1,2-Tetrachloroethane was greater than the control limits in the LCS extracted on 8/20/2014. There were no positive results for this target analyte in the associated field samples; therefore, no action was required for this outlier.

Laboratory Duplicates

Internal laboratory duplicate analyses are performed to monitor the precision of the analyses. Two separate aliquots of a sample are analyzed as distinct samples in the laboratory and the RPD between the two results is calculated. Duplicate analyses should be performed once per analytical batch. If one or more of the samples used has a concentration less than five times the reporting limit for that sample, the absolute difference is used instead of the RPD. For organic analyses, the RPD control limits are specified in the laboratory documents. For inorganic analyses, the RPD control limit is 20 percent. Laboratory duplicates were analyzed at the proper frequency and the specified acceptance criteria were met, with the following exceptions:

SDG SXH0105: (Total Lead) A laboratory duplicate analysis was performed with an RPD that exceeded the control limit; however, it was performed on a sample that was not associated with the samples in this SDG. For this reason, no action was required for this outlier.

SDG SXI0121: (Dissolved Manganese) A laboratory duplicate analysis was performed with an RPD that exceeded the control limit; however, it was performed on a sample that was not associated with the samples in this SDG. For this reason, no action was required for this outlier.

Field Duplicates

In order to assess precision, field duplicate samples are collected and analyzed along with the reviewed sample batches. The duplicate samples are analyzed for the same parameters as the associated parent samples. Precision is determined by calculating the RPD between each pair of samples. If one or more of the sample analytes has a concentration less than five times the reporting limit for that sample, then the absolute difference is used instead of the RPD. The RPD control limit is 20 percent.

SDG SXH0105: One field duplicate sample pair, MW8 (14-15’) and Duplicate, was submitted with this SDG. The precision criteria for all target analytes were met for this sample pair.

SDG SXI0121: One field duplicate sample pair, MW-8-091714 and MW-Dup-091714, was submitted with this SDG. The precision criteria for all target analytes were met for this sample pair, with the exception of dissolved manganese. The positive result and reporting limit for this target analyte were qualified as estimated (J/UJ) in these samples.


File No. 00504-101-01

SDG SXJ0093: One field duplicate sample pair, MW-8-101314 and MW-Dup-101314, was submitted with this SDG. The precision criteria for all target analytes were met for this sample pair.

Overall Assessment

As was determined by this data validation, the laboratory followed the specified analytical methods. Accuracy was acceptable, as demonstrated by the surrogate, LCS, and MS/MSD percent recovery values. Precision was acceptable, as demonstrated by the LCS/LCSD, MS/MSD, and laboratory/field duplicate RPD values, with the exceptions noted above.

All data are acceptable for the intended use, with the following qualifications listed below in Table 2.

APPENDIX C Report Limitations and Guidelines for Use

APPENDIX C

REPORT LIMITATIONS AND GUIDELINES FOR USE1

This appendix provides information to help you manage your risks with respect to the use of this report.

Environmental Services Are Performed for Specific Purposes, Persons and Projects

GeoEngineers has performed this assessment of the Lincoln Avenue Car Wash site in Yakima, Washington

in general accordance with the Work Plan dated July 11, 2014. This report has been prepared for the

exclusive use of the Washington Department of Ecology. This report is not intended for use by others, and

the information contained herein is not applicable to other properties.

GeoEngineers structures our services to meet the specific needs of our clients. For example, an

Environmental Site Assessment (ESA) study conducted for a property owner may not fulfill the needs of a

prospective purchaser of the same property. Because each environmental study is unique, each

environmental report is unique, prepared solely for the specific client and property. No one except the

Washington Department of Ecology should rely on this environmental report without first conferring with

GeoEngineers. Use of this report is not recommended for any purpose or project except the one originally

contemplated.

This Environmental Report is Based on a Unique Set of Project-Specific Factors

This report has been prepared for the Lincoln Avenue Car Wash site in Yakima, Washington. GeoEngineers

considered a number of unique, project-specific factors when establishing the scope of services for this

project and report. Unless GeoEngineers specifically indicates otherwise, it is important not to rely on this

report if it was:

■ not prepared for you,

■ not prepared for your project,

■ not prepared for the specific site explored, or

■ completed before important project changes were made.

If important changes are made to the project or property after the date of this report, we recommend that

GeoEngineers be given the opportunity to review our interpretations and recommendations. Based on that

review, we can provide written modifications or confirmation, as appropriate.

Reliance Conditions for Third Parties

Our report was prepared for the exclusive use of our Client. No other party may rely on the product of our

services unless we agree to such reliance in advance and in writing. This is to provide our firm with

reasonable protection against open-ended liability claims by third parties with whom there would otherwise

be no contractual limits to their actions. Within the limitations of scope, schedule and budget, our services

1 Developed based on material provided by ASFE, Professional Firms Practicing in the Geosciences; www.asfe.org.


have been executed in accordance with our Agreement with the Client and generally accepted

environmental practices in this area at the time this report was prepared.

Environmental Regulations Are Always Evolving

Some substances may be present in the vicinity of the subject property in quantities or under conditions

that may have led, or may lead, to contamination of the subject property, but are not included in current

local, state or federal regulatory definitions of hazardous substances or do not otherwise present current

potential liability. GeoEngineers cannot be responsible if the standards for appropriate inquiry, or

regulatory definitions of hazardous substances, change or if more stringent environmental standards are

developed in the future.

Uncertainty May Remain Even After This Phase II ESA is Completed

Performance of a Phase II ESA is intended to reduce uncertainty regarding the potential for contamination

in connection with a property, but no ESA can wholly eliminate that uncertainty. Our interpretation of

subsurface conditions in this study is based on field observations and chemical analytical data from widely

spaced sampling locations. It is always possible that contamination exists in areas that were not explored,

sampled or analyzed.

Subsurface Conditions Can Change

This environmental report is based on conditions that existed at the time the study was performed. The

findings and conclusions of this report may be affected by the passage of time, by man-made events such

as construction on or adjacent to the subject property, by new releases of hazardous substances, or by

natural events such as floods, earthquakes, slope instability or groundwater fluctuations. Please contact

GeoEngineers before applying this report for its intended purpose so that GeoEngineers may evaluate

whether changed conditions affect the continued applicability of the report.

Soil and Groundwater End Use

The cleanup levels referenced in this report are site- and situation-specific. The cleanup levels may not be

applicable for other properties or for other on-site uses of the affected soil and/or groundwater. Note that

hazardous substances may be present in some of the on-site soil and/or groundwater at detectable

concentrations that are less than the referenced cleanup levels. GeoEngineers should be contacted prior

to the export of soil or groundwater from the subject property or reuse of the affected soil or groundwater

on-site to evaluate the potential for associated environmental liabilities. We are unable to assume

responsibility for potential environmental liability arising out of the transfer of soil and/or groundwater from

the subject property to another location or its reuse on-site in instances that we did not know or could not

control.

Most Environmental Findings Are Professional Opinions

Our interpretations of subsurface conditions are based on field observations and chemical analytical data

from widely spaced sampling locations at the subject property. Site exploration identifies subsurface

conditions only at those points where subsurface tests are conducted or samples are taken. GeoEngineers

reviewed field and laboratory data and then applied our professional judgment to render an informed

opinion about subsurface conditions throughout the property. Actual subsurface conditions may differ,


sometimes significantly, from those indicated in this report. Our report, conclusions and interpretations

should not be construed as a warranty of the subsurface conditions.

Do Not Redraw the Exploration Logs

Environmental scientists prepare final boring and testing logs based upon their interpretation of field logs

and laboratory data. To prevent errors or omissions, the logs included in an environmental report should

never be redrawn for inclusion in other design drawings. Only photographic or electronic reproduction is

acceptable, but separating logs from the report can create a risk of misinterpretation.

Read These Provisions Closely

It is important to recognize that the geoscience practices (geotechnical engineering, geology and

environmental science) are less exact than other engineering and natural science disciplines. Without this

understanding, there may be expectations that could lead to disappointments, claims and disputes.

GeoEngineers includes these explanatory “limitations” provisions in our reports to help reduce such risks.

Please confer with GeoEngineers if you need to know more about how these “Report Limitations and

Guidelines for Use” apply to your project or property.

Biological Pollutants

GeoEngineers’ Scope of Work specifically excludes the investigation, detection, prevention or assessment

of the presence of Biological Pollutants. Accordingly, this report does not include any interpretations,

recommendations, findings or conclusions regarding the detecting, assessing, preventing or abating of

Biological Pollutants, and no conclusions or inferences should be drawn regarding Biological Pollutants as

they may relate to this project. The term “Biological Pollutants” includes, but is not limited to, molds, fungi,

spores, bacteria and viruses, and/or any of their byproducts.

A Client that desires these specialized services is advised to obtain them from a consultant who offers

services in this specialized field.
