The samples will be analyzed on a normal laboratory schedule <br /> requiring approximately two weeks (ten working days) for completion. <br /> Once the samples have been analyzed, the results must be evaluated <br /> for use of the soil as excavation backfill, on-site treatment, <br /> and/or off-site treatment/disposal. The results of that evaluation <br /> will be summarized in a short report which will be submitted to West <br /> Clay Properties and the SJCEHD upon completion. That short report <br /> could be used to evaluate some disposal/remediation alternatives for <br /> the soil. <br /> 7) Materials Testing/Inspection of Excavation Backfill Materials <br /> Currently, it is proposed that the excavation be backfilled by the <br /> excavation contractor from the excavation bottom to a depth of 30 <br /> feet below grade with a pea gravel backfill. Those materials, when <br /> properly placed, will provide a stable surface without the addition <br /> of excess water. From a depth of 30 feet to existing grade the <br /> excavation will be backfilled by the excavation contractor with <br /> Engineered Fill. The Engineered Fill should be moisture-treated at <br /> the surface, placed into the excavation and wheel-roiled to 90 <br /> percent relative compaction (ASTM D-1557-86) . Every reasonable <br /> effort should be made to limit excess water in the Engineered Fill. <br /> Observation of the pea gravel placement and compaction testing of <br /> the Engineered Fill is separate from this bid proposal and will be <br /> • determined by West Clay Properties at a later date. <br /> 8) Reporting <br /> Upon completion of the field activities and receipt of the <br /> analytical results, a report of findings will be prepared for West <br /> Clay Properties and agency review. The report will include: <br /> A description of all background activity, results, and <br /> conclusions of previous soil and groundwater assessments. <br /> A description of the field activities, observations, and <br /> protocols <br /> Lithologic logs <br /> Tabulated results of soil and groundwater samples with copies of <br /> certified results <br /> A groundwater elevation contour map for the monitoring event <br /> and an estimate of the groundwater gradient direction <br /> Description and documentation of QA/QC procedures employed <br /> for field and laboratory work <br /> Consultant ' s conclusions and recommendations based on the <br /> data acquired <br /> • 9) Additional Monitoring Events <br /> Following the completion of Task 8 . , additional groundwater <br /> monitoring will likely be necessary. Please include an itemized bid <br /> for the quarterly sampling of five (5) wells . The wells must be <br />
