Page 2 of 5 <br /> Task 2:Compliance Groundwater Monitoring,Additional Sampling Event <br /> In June 2021,the Washington State Department of Ecology requested one additional compliance groundwater <br /> sampling event to be completed during summer 2021.The scope of work related to this task is as follows: <br /> 1. Update GeoEngineers' health and safety plan for on-site field work. <br /> 2. Complete one additional quarterly groundwater compliance sampling event of five site monitoring wells <br /> using low-flow samplingtechniques.Submit the groundwater samples for chemical analysis of PAHs,diesel <br /> and oil-range petroleum hydrocarbons, gasoline-range petroleum hydrocarbons, volatile organic <br /> compounds,total and dissolved arsenic,total and dissolved chromium,and total and dissolved lead. Prior <br /> to sampling,the wells will be purged until water quality parameters stabilize and/or three well volumes are <br /> removed. Chemical testing will be performed on a standard turnaround time by an Ecology-certified <br /> environmental laboratory under subcontract to GeoEngineers. Depths to groundwater will be measured <br /> prior to sampling. <br /> 3. Evaluate groundwater chemical analytical results relative to MTCA cleanup levels. <br /> 4. IDW water from monitoring well installation will be drummed and left on site at a location designated by <br /> the City. Costs for IDW disposal are not included in this scope of work;the City has advised IDW disposal <br /> will be completed by others during Property redevelopment. <br /> 5. Incorprorate the results of the 5th compliance groundwater monitoring event into the compliance <br /> groundwater monitoring report summarizing the results of the quarterly compliance groundwater <br /> monitoring events. The draft report will be submitted to the City for review and comment. Comments will <br /> be incorporated into the final prior to submittal to Ecology under the VCP. <br /> Task 3: Regulatory Support <br /> 1. Communicate and meet with Ecology to discuss the additional groundwater monitoring results, VCP <br /> submittals and Ecology opinion letter. <br /> 2. Submit the 5th quarterly event groundwater results into the environmental data into Ecology's <br /> Environmental Information Management(EIM)database as required under MTCA. <br /> 3. Provide supporting environmental consulting or meetings with the City related to the compliance <br /> monitoring. <br /> 4. Perform routine project management, budget tracking,and invoicing. <br /> FEE ESTIMATE <br /> The total estimated fee for this Scope of Work is $27,960 which consists of GeoEngineers' labor ($13,377) <br /> and subcontracted services($14,583).A breakdown of the fee estimate is summarized in Exhibit B. <br /> GeoEngineers,Inc. <br /> File No.0661-108-03 <br />
