EXECUTIVE SUMMARY

FormerWelch's Facility Kennewick, Washington

This report summarize$ the environmental work performed at the 1,0East Bruneau Avenue, Kennewick, Washington (subject prciperty or Site), and presents the results of the current Remedial lnvestigation (RI) and PBS' findings and conclusions. The study is designed to provide environmental information concerning the $Ubject property to evaluate compliance in accordance

. with an Agreed Order (AO) between Welch's Foods and the Washington State Department of Ecology (WDOE). . .

The results of the Rl.provide a summary of work at the si te, to date, and a framework for the future Feasibility Study (FS). No further contamination was detecteQ in soil or groundwater during the field portion of the RI work. Groundwater flow direction was determined by the RI to be northerly at a low winter gradient. Based on analytical results, released oil at the unconfined aquifer surface has travelled no more than 70 feet north of the contaminant release location;. a small percentage of the total distance groundwater has tr~lVelled. Release quantities have been estimated based on the RI and analyticQI d;:~ta .

. Following the lnterim Remedial Action at the site conducted in 2006, remaining risk.app~ars unchanged. Additional risk assessment and recommendations concerning future work at the site are forthcoming through the Feasibility Study (FS) ..

2.2 Phase 11 Environmental Assessment In July 2006, PBS conducted a Phase 11 onthe subject property by completing environmental oversight of seven soil borings to groundwater with soil and water samples collected for analysis (Project #61396.00). Soil borings were corilpleted adjacent to the UST, lines and the shop area to the east. No contamination was observed near the tank. Groundwater and soil contamination (in heavy oil) was detected along the UST lines to the east of the tank. Further work was recommended to characterize and cleanup the contamination (see Appendix D).

2.3 lnterim Soil Excavation Remedial Action In response to the presence of heavy oil contamination from the Phase 11, in August and September 2006, PBS oversaw excavation along the UST fuellines to the Boiler Building (Project #61405.00). No contamination was detected and it was later determined that the source of the leakage was immediately to the south of the lines at the location of two former 12,000 gallon bunker fuel USTs removed in the mid 1980s. lnterim remedial action excavation proceeded at the location of the former USTs, with contaminated soil removed and hauled to an offsite disposal facility during that project (see Appendix D). This interim action resulted in removing a significant amount of oil from the soil and upper groundwater table zone to reduce the amount of oil available for further oil movement with groundwater.

2.4 UST Decommissioning and Site Assessment A Limited Underground Storage Tank (UST) Assessment was performed in September 2007, concurrent with the closure of one 50,000 gallon bunker fuel UST at 1 O East Bruneau Street, Kennewick, Washington (Project #61768.00). This project was required by the real estate agreement between Welch's Foods and J. Lieb and is nota portion of the AO. lnformation concerning this project is added to the RI report, because if leakage had occurred, the scope of work concerning the RI could have been affected. Previous assessment immediately adjacent to the UST (see Section 2.2, above) suggested that no leakage from the UST had occurred. The decommissioning/closure was performed by K. Kaser Company, with PBS environmental oversight.

The UST formerly contained bunker fuel, which was pumped out prior to decommissioning. Natural gas lines close to the tank were removed to support the UST decommissioning project. Soil sampling was completed around the tank base and in the stockpiled soil. Samples were laboratory analyzed for heavy oil, with results indicating that no release of fuel into the soil had occurred. The UST was closed and removed from the site for disposal on Septembr 21, 2007. The tank basin was backfilled with clean onsite soil and offsite structural fill after the project was completed (see Appendix D).

3.0 PURPOSE ANO SCOPE The purpose of the RI was to provide additional soil and groundwater data to allow a more accurate assessment of the risk posed to human health and the environment by the contamination at 1 O East Bruneau Avenue. This investigation provides further environmental information in support of Agreed Order FS #89931898 (AO) between Welch's Foods and the Washington State Department of Ecology (WDOE) and further supports a future feasibility study (FS) toward remedial action at the Site.

Collecting soil samplesconcurrently with the establishment of three monitoring wells on the subject property near the area of the reported contamination using air rotary techniques.

Analyzing the samples for heavy oil-fraction petroleLim hydrocarbons as well as a full suite of constituents as required by the AO.

lnterpreting the findings with respect to Washington cleanup leveis for petroleum-contaminated sites (WAC 173-340).

Providing a report that includes ali information requirements listed in the AO.

Providing information for the future completion of a FS.

FIELD METHODS On January 23 and 24, 2008, PBS oversaw the completion of three borings and construction of three monitoring wells on the subject property. The w_lls were completed using a track-mounted, air rotary drill operated by Michalson Drilling, Richland, Washington. Locations of the borings are shown on Figure 2. A request for utilities locate was made and locations were inspected prior to start of work. In addition, a private locate was completed on the site by A-1 Locating of Richland, Washington.

Prior to beginning drilling, the drillers, PBS and affected J. Lieb personnel reviewed the Health and Safety Plan (HASP) for the project (see Appendix E). The HASP provided information concerning the location of the nearest hospital, personal protective equipment requirements, toxicity characteristics of the contaminant and contact information. The HASP was completed prior to this project and approved by WDOE as required by the AO.

Also in accordance with the AO, a Sampling and Analysis Plan (SAP) was completed. The SAP provides detailed information on the location and depth of the wells, well construction specifics, analytical procedures, contaminated soil cuttings and groundwater handling procedures, a schedule and contact list (see Appendix F). The SAP was also approved by WDOE prior to beginning the project. A schedule change was approved by WDOE, with that approval provided in Appendix F.

As provided in the SAP, ali sampling equipment ws decontaminated between borings and during soil and water sampling using a detergent (Aiconox) wash and tap water rinse. Ali collected samples were placed in an ice chest that was cooled to approximately 4 Centigrade for the duration of the fieldwork. The samples were delivered to Friedman and Bruya Laboratory, Seattle, Washington, and CLS Laboratory, Pasco, Washington under chain of custody documentation within the required holding times for the analytical methods. Analytical results are provided hSection 5.1

Graphic logs of subsurface soil conditions are presented in Appendix B. Copies of ali laboratory reports and sample chain-of-custody forms are presented in Appendix C. Results of testing are discussed below, and are also included in Tables 1 and 2.

PBS

4.1 Well lnstallation Procedures One major purpose of the onsite drilling was the construction of monitoring wells. Wells were constructed in accordance with WDOE monitoring well construction regulations provided in WAC Chapter 173-160 and 173-162. A total ofthree monitoring wells (MW-1

Engineering + Environmental 4



PBS

through MW-3) were completed in the area of the release described in Section 2.3 above. The flush mounted wells were placed as indicated in the SAP and completed to approximately 27 feet below ground surface (bgs ). Groundwater was indicated to be located approximately 20 feet bgs (see welilogs, Appendix B).

Welis were constructedwith 2" PVC casings to a depth of at least 6 feet below the surface of the unconfined groundwater table elevation. With the use of 10 feet of screened casing, approximately 4 feet of screen wasplaced above the unconfined water table. One weli (MW #1) was constructed upgradient of the location of the contamination, with two welis (MW #2 and MW #3) constructed downgradient to the northwest and northeast, respectively. Wells were constructed in such a configuration that the top of casing could be surveyed and the surface of the groundwater table could be determined, along with groundwater flow direction and gradient. Well surveying was completed by PBS, with an accuracy of 0.01 feet vertical accuracy measured against a relative datum (see Appendix G).

4.2 Soil Sampling Procedures Ali recovered soils were headspace-screened for volatile organic compounds using a portable Mini-RAE photoionization detector (PIO). Soil samples were coliected with a drive sampler and placed into 4-ounce glass sample jars with Teflon lid liners. The SAP calied for collecting two soil samples per weli at approximately 1 5 and 20 feet bgs; beca use of heavy cobbles that would not fit in a split spoon, it was not possible to coliect any samples from 20 feet bgs.

4.3 Water Sampling Procedures Quarterly groundwater monitoring began on February 1, 2008 after the welis had been constructed. Ali three welis were monitored and sampled. Prior to sampling monitoring wells, water table elevations were recorded by PBS with an electronic water levei indicator. PBS used bailers and a 12 volt submersible pump to purge and sample the monitoring wells. Prior to sampling, each well was purged with an estimated 3 well casing volumes of water removed. Concurrently with purging, the groundwater parameters of conductivity, pH, and temperature were recorded with a water quality meter, until parameters stabilized. Laboratory-manufactured conductivity and pH standard solution values were recorded during purging to check data accuracy. Ali waste water generated from sampling and purging was held on the property, in 5-gallon buckets, for later sampling and disposal (see SAP - Appendix F). .

4.4 Quality Assurance Sample QA/QC included collecting one duplicate groundwater sample and soil sample which were submitted to the laboratory blinq-labeled. Well #23 represents a second blind-labeled QA/QC sampling of Well #3, from water and soil samples taken at the same time as the Well #3 sample collections. Ali results for were non-detect (see Table #1 ). Excessive deviation between the initial and blind labeled results would be expected to trigger further QA/QC procedures. The laboratory's daily batch quality contrai testing was also reviewed for data quality (see SAP Appendix F).

4.5 lnvestigation-Derived Wastes A total of six 55-gallon drums were left near a loading dock on the south side of Bruneau

Street on the J. Lieb site. The drums (containing drill cuttings) are sealed and labeled. Analytical results suggest that those drummed soils are clean.

5.0 FINDINGS

PBS

5.1 Analytical Results Soil samples were collected during well installation, with groundwater samples collected after the wells were developed and purged. Soil and groundwater analytical procedures were performed as indicated in Section VIl (3) of the AO andas listed below. Testing was designed to determine whether the following hazardous substances have been released: benzene, toluene, ethyl benzene, xylenes (8TEX), other petroleum products, carcinogenic polycyclic aromatic hydrocarbons (PAHs), and napthalenes. Petroleum products were tested through Northwest total petroleum hydrocarbons- diesel method (NWTPH-Dx and NWTPH-Dx Extended). The list of constituents and analytical procedures is provided below:

Constituent Petroleum Products (Oil) Petroleum Products (heavy oil) 8enzene Toluene Ethyl benzene Xylenes PAHs Napthalenes

Proposed Analytical Procedures EPA Method 8015M (NWTPH-Dx) EPA Method 8015M (NWTPH-Dx Extended) EPA Method 80218 EPA Method 80218 EPA Method 8021 8 EPA Method 80218 EPA Method 8270C EPA Method 8270 SIM

The results of analytical testing indicated the compounds analyzed did not exceed laboratory detection limits in any of the soil or groundwater tested at the location of the monitoring wells. No significant flags were observed on the laboratory data. See analytical results provided in Table #1; attached to the report.

Further discussion concerning the known pr~sence of contamination on the site (including the earlier assessments and interim remedial action) is provided in Section 5.5, below.

5.2 Soil The soils encountered consisted of sand, gravei, cobbles and boulders, with minar silt (see Logs, Appendix 8). A surface layer of asphalt was present at MW #2 and #3, with a soil surface at MW #1. Saturated soils were encountered at depths of 19 to 21 feet bgs. There were no field observations, photoionization detector or analytical indications of 'soil contamination in any of the well borings associated with the RI. Further discussion of known contamination is provided in Section 5.5, below. The laboratory results for soil are presented in Table 1.

5.3 Groundwater The groundwater samples were collected following completion of the wells on February 1 , 2008 by the method described in Section 4, above. No sheen or petroleum odor was observed in any of the wells constructed for 1this project. Table #1 provides information concerning groundwater contaminants. A review of the earlier Phase li report indicates that contamination is present on top of groundwater at the former location of 8oring #4 (see site plan) immediately north of the old tanks and the point of contaminant release. Lesser contamination was detecte~ in 8oring #7, just southeast of the former locations of the tanks.




PBS

Groundwater table elevations were taken and the wells were surveyed in support of calculating groundwater flow direction (Appendix G). The depth to groundwater was approximately 1-foot deeper than during the summer season when the Phase li was completed on the site. This information suggests that some irrigation water loss from canais to the unconfined aquifer occurs during the irrigation season (April to October), increasing groundwater table elevation during that period.

January 2008 groundwater flow direction was calculated and indicated to be approximately North, 4 degrees East at a gradient of 0.07 feet/1 00 feet. A steepening of the gradient is expected during the late spring season when irrigation water again begins to elevate the water table. No pump tests or slug tests have been completed, but, based on the fact that the soil in the upper water table zone is clean sandy gravei, some judgment concerning hydraulic conductivity can be provided. Qualitative information for similar materiais suggests the aquifer hydraulic conductivity approximates 100 feetlday. Using the estimated hydraulic conductivity, known aquifer surface slope and Darcy's Law calculations, the velocity of groundwater flow in the non-irrigation season is estimated at 14 days/foot. This figure is expected to be a low end and the gradient will steepen in the spring allowing faster groundwater flow (Appendix G).

5.4 Focused Evaluation A summary of the previous environmental investigation and interim remedial action is provided in Section 2 of this report. lnformation for this section is derived from the recent RI boring and monitoring well work, as well as the Phase 11 (PBS Project #61396.00) and the lnterim Remedial Action (PBS Project #61405.00). Results of the UST decommissioning _ project (PBS Project #61786.00) indicated no added soil or groundwater contamination from that sector.

Field observation suggests that the flow velocity of the released oil is markedly slower than the movement of groundwater. With a low end groundwater flow velocity of 14 days per foot and 20 years of time (since the mid 1980s when the two 12,000-gallon USTs were removed) groundwater flow would have travelled 500 feet or further. The downgradient groundwater flow from the release would have then travelled far beyond Boring #5 and Monitoring Wells #2 and #3.

Appendix H calculation approximate that a total of approximately 2,577 gallons of oil may h ave been released to the soil and groundwater from the tanks, based on the maximum contamination levei at 20,900 milligrams combined oil and diesel grade product per kilogram of soil. The stated contaminant levei reflects the highest soil contamination levei detected in the oil impacted soil prior to hauling it to a landfill during the interim remedial action.

Water is a polar molecular substance and oil is non-polar. The specific gravity of the product is 0.97, which suggests it floats on water (field observations from the borings and interim excavation support this information). The non-polar oil is hydrophobic with respect to water and tends to form round globs of oil in water. Further, the hydrophobic oil tends to form a bond with the soil and rock, with the soil providing a "refuge" from the polar water. Based on oil specific gravity these actions take place in the upper portion of the unconfined aquifer.

In effect, the soil forms a sieve, binding the oil away from the water and restricting the distance the oil has migrated. Although the oil obviously travelled north of Boring #4, RI information indicates it could have travelled no further than 70 feet north of the release site. Ata high end estimate, the oil has travelled less than 14% of the distance water has travelled in a similar time frame.

Of course any water soluble components of the oil (for example BTEX) would travei as fast as the water; RI analytical results for volatile and semi-volatile substances indicated that currently, no such soluble substances were detected (see Table #1 ). No soluble substances were detected in the earlier Phase li either.

The earlier nterim remedial action was designed, in part, to lessen the free head of oil over water and reduce the possibility of further oi I migration. During the nterim remedial action approximately 2,261 gallons of oil (not including soil) was removed from the site, significantly reducing risk and the probability that oil is continuing to advance in the groundwater system. A year of quarterly monitoring and groundwater flow direction analysis could be considered in ali three wells to help establish if the oil is soil bound and no further oil movement is occurring.

5.5 Gonclusions The results of the RI provide a summary of work at the site to date and a framework for the future FS. No further contamination was detected in soil or groundwater during the field portion of the RI work. Groundwater flow direction was determined by the RI to be northerly at a low winter gradient. Released oil at the unconfined aquifer surface h as travelled no more than 70 feet north of the contaminant release location; a small percentage of the distance groundwater has travelled. Release quantities have been estimated based on the RI and analytical data.

5.6 lnterim Risk Evaluation At this time only a qualitative statement concerning risk is provided by PBS, beca use if an immediate further environmental concern were detected during the RI, nterim action could be prudent to head off contaminant uptake by any receptors.

No indication of risk, beyond what was provided in the Phase 11 and lnterim Remedial Action, is provided. As discussed in the Phase 11, the adjacent water well on the property is

. plumbed into a confined aquifer at +400 feet below ground surface, with a positive (artesian) pressure at the well head disallowing any contaminant entry into that system. No other nearby wells were noted. A small amount of contamination is present under the railway right-of-way to the south (Boring #7, approximately 7 feet south of the former leaking tanks); with groundwater flow to the north, little further risk in that direction is indicated. The contaminant is non-volatile sono area basement air-quality contamination intrusion is suspected. Non-human ecological risk appears to be low because no surface contamination is present and the contaminant has not travelled as far as the Columbia River in groundwater.

The Conceptual Site Model and other more detailed components of risk will be addressed during the FS portion of the project. The concept of risk has a direct bearing on the feasibility, cost and type of remedial pathway chosen for the FS, with a focused risk assessment scheduled for that study.

Data Q.ualifiers & Definitions a- The analyte was detected ata levelless than five times the reporting limit. The RPD results may not pro vide reliable information on the variability of the analysis. Al- More than one compound of similar molecule structure was identified with equal probablility. b - The analyte was spiked at a levei that was less than five times that present in the sample. Matrix spi:ke recoveries niay not be meaningfi.il~ .. ca - The calibration results for this range fell outside of acceptance criteria. The value reported is an estima te. c - The presence of the analyte indicated may be due to carryover from previous sample injections. d - The sample was diluted. Detection limits may be raised due to dilution. ds - The sample was diluted. Detection limits are raised due to dilution and surrogate recoveries may not be meaningful. dv- Insufficient sample was available to achieve normal reporting limits and limits are raised accordingly. fb- The analyte indicated was found in the method blank. The result should be considered an estimate. fc - The compound is a common laboratory and field contaminant. hr - The sample and duplicate were reextracted and reanalyzed. RPD results were still outside of control limits. The variability is attributed to sample inhomogeneity. ht- The sample was extracted outside of holding time. Results should be considered estimates. ip - Recovery fell outside of normal controllimits. Compounds in the sample matrix interfered with the quantitation of the analyte. j- The result is belownormal reporting limits. The value reported is an estimate. J - The internai standard associated with the analyte is out of controllimits. The reported concentration is an estimate. jl- The analyte result in the laboratory control sample is out of controllimits. The reported concentration should be considered an estimate. jr - The rpd result in laboratory control sample associated with the analyte is out of controllimits. The reported concentration should be considered an estimate. js - The surrogate associated with the analyte is out of controllimits. The reported concentration should be considered an estimate. lc - The presence of the compound indicated is likely due to laboratory contamination. L- The reported concentration was generated from a library search. nm - The analyte was not detected in one or more of the duplica te analyses. Therefore, calculation of the RPD is not applicable. pe --:: T}le_ sample was received in a container not approved by the method. The value reported should be considered an -estima te.

pr- The sample was received with incorrect preservation . .The value reported should be considered an estima te. ve - The value reported exceeded the calibration range established for the analyte. The reported concentration should be considered an estimate. vo - The value reported fell outside the controllimits established for this analyte. x - The pattern of peaks present is not indicative of diesel. y- The pattern ofpeaks present is not indicative of motor oil.

Re: LIMITED UNDERGROUND STORAGE TANK (UST) ASSESSMENT, PCBs INSPECTION AND WELL WATER REVIEW AT WELCHS FOODS, 10 EAST BRUNEAU, KENNEWICK, WASHINGTON PBS PROJECT NlJMBER #61396.00

Dear Mr. Beamer:

In August 2006, at your request PBS Engineering and Environmental (PBS) completed a Limited UST Assessment, PCBs fuspection and well water review at the Welchs property. This report provides a summary of the assessment results.

BACKGROUND

Food processing has occurred at the plant location since approximately 1925. During a portion o f that time a 50,000-gallon bunker fuel UST system has been providing fuel to power the boiler system. At this time the UST system only provides badcup power, with the main heating supplied by natural gas. An earlier UST assessment was completed by others in January 2006, with results not providing information on groundwater. Bank: o f the W est engaged PBS during June of 2006 to complete a Phase I Environmental Assessment on the property, with results of that assessment recommending further work to assess groundwater and soil near the UST system and fuellines.

Recent information indicates that 2 - 12,000 gallon USTs containing bunker fuel were removed from the site between 1974 and 1978. The location of those units were 120 feet east of the southwest comer o f the subject property, with the pump unit on the south side o f the two north oriented USTs. Excavation based remedial action has begun to remove bunker fuel contaminated soil related to those USTs .

. FIELD METHODS

The fieldwork for this assessment was conducted from July 31 to August 11, 2006; with a utility locate completed on the property prior to beginning work. After arrival on the property, Welchs personnel, PBS and the drilling contractor reviewed the location of the UST and underground fuellines as well as other utilities in the area prior to beginning drilling.

After the si te was checked for utility locations, air rotary Tubex system drilling was provided by Environmental West Exploratio~, Spokane, Washington to sample soil adjacent to the UST, lines

and maintenance area of Building #4. Seven borings, with sampling, were completed. Drill holes were completed at the locations shown on Figure l. Mter the borings were completed and the samples were collected, the boles were backfilled with bentonite. Soil samples were collected into4-ounce glassjars, with water ~amples collected with disposable bailers into 40 ml vials and 12 liter amber bottles. All samples were shipped in iced coolers -to a certified -environmental laboratory, within the required holding time ofthe chosen analytical method.

PBS logged the borings in general accordance with the Unified Soil Classification System; see attached boring logs. In general, materiais encountered in the borings included a surface layer of asphalt or grass. V arious mixtures of sandy gravei and sand were present in most o f the borings to approximately 25 feet below ground surface at the base ofthe borings. See the attached boring logs for further information. Groundwater was encountered in the borings at between 20 and 23 feet below ground surface.

LABORATORY RESULTS

Ali samples were submitted to Friedman and Bruya Laboratory in Seattle, Washington for analysis by total petroleum hydrocarbons- hydrocarbon identification method; (NWTPH-HCID) a qualitative procedure to identify the fraction and type of hydrocarbon in the sample. Other analysis was completed for total petroleum hydrocarbons.- diesel extended method (NWTPH-Dx) and volatile organic constituents (VOCs). Table -1 provides a summary of analytical results for the UST assessment; fuel contamination was encountered in borings #4 and #7 as indicated below. The laboratory report is attached following this report.

See Figure I for boring/sample locations.

CONCLUSIONS

Analytical results mdicate that petroleum hydrocarbon impact above Washington State Department of Ecology (WDOE) Model Toxic Control Act (MTCA) Method A cleanup leveis were found in groundwater sampled at the Welchs site from Borings #4 and #7. Field indications of bunker fuel contamination were observed in both borings. The fuel was encountered only in groundwater, with no soil contamination above the water table elevation encountered. Boring #4 was located approximately one foot north o f the existing bunker fuellines and at the north end o f the former 12,000-gallon USTs on the property. Boring #7 was approximately 25 feet south of the existing bunker fuellines and 18 feet southeast of the south side of the fonner UST pump house. The larger amount of contamination was observed in Boring #4, which was judged to be downgradient of the confmned leaks that occurred in the lines and pump house of the earlier 12,000 gallon USTs. No leakage was suspected from the current 50,000 gallon UST and piping system.

No contamination was detected in Boring #5, which was approximately 80 feet downgradient from the suspected leak locations. No contamination was detected in Borings #1, #2 and #3 which were adjacent and downgradient from the existing onsite 50,000 gallon UST. Boring #6 was completed further east on the site, immediately north of the Building #4 machine shop to check for leakage from that area. No contamination was detected in Boring #6, suggesting that no contaminants had escaped from that area.

PCBsiSSUES

In support of the project, PBS completed a review of onsite privately owned transformers and capacitors to check for PCBs. Mr. Gary Splattstoesser, of Benton County PUD, aided in the review. PBS walked through the facility and observed approximately 7 floor mounted oil-less transformers. In addit1on, approximately 10 -50 KVA capacitors were observed in the various production areas on the site. Several of the capacitors in the southwest portion o f Building #4 were indicated to contain Areovox - Supemol transformer oil. The Supemol oil was indicated to be non-PCBs containing. No other PCBs containing fixtures were observed on the site; no PCBs issues with transformers or capacitors are suspected. Individual fluorescent ballasts were examined for PCBs in the maintenance shop area of Building #4 (the oldest building onsite); labels on the ballasts observed indicated "No PCBs". Checking alllight ballasts was beyond the scope of the project, but results at this time suggest that "No PCBs" ballasts will be present throughout.

WATER SUPPLY WELL ISSUES

. One -pr~duction- suppfy well is-located immediately west of the Boiler Building. Well construction data indicates the well is 548 feet deep, with unperforated casing to 365 feet below ground surface in basalt bedrock. Six pounds of artesian pressure is present at the well head. Laboratory analytical data was provided to PBS by Welchs, with analysis for inorganic chemicals, synthetic organic chemicals, metais, pesticides, herbicides, petroleum chemicals, volatile organic chemicals, trihalomethanes, semi-volatiles, PCBs and dioxins. Detected constituents included fluoride (0.9 mg/1), sulfate (50 mg/1), sodium (100 mg/1), hardness (11 mg/1), total dissolved solids (319 mg/1), conductivity (503 umhos/cm) and turbidity (0.5 NTUs); ali results are within regulatory MCLs. The detected dioxins constituent (2,3,7,8 - TCDD) indicated a concentration of 203.597 picograms/liter in the production well; this can also be written as 203.597 x 10-15 grams/1. EPA Region 9 Preliminary Remediation Goals (PRGs) indicates that the dioxins remediation goal is 4.5 x 10-7 grams/1, suggesting that dioxins leveis within the well are safe. Ali of the other indicated sample results are non-detect for all constituents. No problems conceming well water contamination are suspected from the supplied analytical analysis. .

RECOMMENDATIONS

In support of due diligence, PBS recommends that the onsite bunker fuel contaminated soil be removed to the degree possible to not jeprodize adjacent building, slab or utility foundations. Removing the contaminated soil will reduce potential future groundwater contamination by ending the gravity transfer of bunker fuel from soil into the groundwater beneath. The contaminated soil should be disposed at an offsite landfill. Clean fill soil can be brought in to replace the contaminated soil. Work to remove the contaminated soil is currently underway through a separate environmental project with Welchs Foods.

In accordance with WDOE - MTCA regulations in Chapter 173-340 W AC, PBS recommends that the release be reported to the WDOE (this action has already been completed). In conjunction with the contact with WDOE, PBS recommends that Welchs consider joining the WDOE Voluntary Cleanup Program (VCP). Joining the VCP will involve submitting this report (anda planned future excavation remedi.l action report) and receiving a decision from WDOE conceming whether cleanup action, risk assessment, installing monitoring wells/monitoring or further assessment is necessary at the W elchs site.

Further inspection of fluorescent light ballasts for PCBs and other potential hazardous bui1ding materiais (lead and asbestos) should be completed prior to future onsite renovations.

LIMITATIONS

This work was performed in accordance with generally accepted practices of other consultants undertaking similar studies during the same time period and geographical area. PBS Environmental observed the same degree of care and skill generally exercised. by other consultants under similar circumstances and conditions. The findings and conclusions of this


report are not scientific certainties, but rather, are based on professional judgement conceming the significance o f data gathered during the course o f this assessment. The recommendations o f this report, or lack thereof, are not considered a legal opinion as to the clients duty conceming due diligence relating to potentialliabilities in leasing, owning, or purchasing real esta te .

. ------- - --

PBS in no~ able to represent that the site or adjoining land contains no hazardous waste, oil or other latent conditions beyond that detected or observed by PBS during this study. The possibility always exists for contaminants to migrate through surface water, air, or groundwater. The ability to accurately address the environmental risk associated with transport in these media is beyond the scope of this investigation.
