I� <br /> �i <br /> Revised Proposal and Estimated Budbet No. P15362.00 <br /> Ekholm Property, Esoalon, CA <br /> F <br /> I <br /> The VET will be performed by applying a vacuum on the test well for a minimum of two hours <br /> and measuring the extraction <br /> well air flow rate and induced vacuum response at observation <br /> wells. A sample of extracted hydrocarbon vapors will be collected at the start and finish of the <br /> VET. The existing wells may be tested to determine any irregularities in induced vacuum <br /> responses that may be seen due to soil inhomogeneities. Thekotron blower and carbon vessels <br /> will subsequently be relocated to each observation well and 4nfluent air samples of extracted <br /> vapors from each well will be collected after 1 hour of operation. Air samples will be submitted <br /> with a chain-of-custody record to a State-certified laboratory, for analyses for the Presence of <br /> BTEX and TPHG. <br /> Task 7. Summary Report Preparation <br /> ` !1 <br /> ' This task includes preparation of a report summarizing all work performed as outlined in tasks <br /> 2 through 6. This report will be prepared for submittal to the APCD, SJCPHS and the RWQCB <br /> for review and approval. The report will detail test procedures followed, field data collected, <br /> laboratory and field data analyses results, conclusions and recommendations. The report will <br /> include a determination of the feasibility of vapor extraction as a remediation strategy, the <br /> location and number of additional vapor wells if any are necessary, and an analysis of offgas <br /> u abatement alternatives. <br /> Please call if you have any questions regarding this estimatedlbudget or the proposed scope of <br /> work. <br /> I� <br /> Respectfully, <br /> RESNA Industries, Inc. <br /> Bill Channell <br /> Senior Project Geologist <br /> I <br /> Enclosure: Estimated Budget (2 pages) <br /> Work Authorization Agreement (2 copies) <br /> 1 <br /> I <br /> 0E <br /> �i <br /> Ekholm Proposal Disk <br /> P362-REV.2 4 <br />
