The costs indicated on the enclosed completed, signed bid response form is based on, but not limited to the work as described in the RFB, item C. Work To Be Performed, Task 1 through Task 3. Specific details of the work to be performed would be provided in the Preliminary Site Assessment Work Pian that will be provided to the client if WHF is selected. The following outline is provided in order to better define the costs indicated on the bid response form. The scope of work involves: 1). The preparation and submission of H&S plan, Work Plan and schedule to San Joaquin County Department of Environmental Health (DEH), and other appropriate agencies for review. 2). Drill a minimum of three (3) soil borings and complete them as two inch monitoring wells. 3). Collect soil samples at five foot intervals for geological interpretation and laboratory analysis (as needed). Deliver all soil samples, under chain of custody, to an analytical laboratory licensed by the State of California for hazardous materials work. The samples shall be analyzed for Total Petroleum Hydrocarbons (diesel) and BTX&E (Benzene, Toluene, Xylene, and Ethyl Benzene). 4). Survey well elevation and develop the monitoring wells by pumping and surge blocking, if required. Containerize all development water in DOT approved 55 gallon drums. 5). Purge the monitoring wells (containerize purge water in 55 gallon drums), measure the depth to groundwater (before and after recovery), and sample the groundwater for laboratory analysis. Deliver all water samples, under chain of custody with appropriate travel blanks and bailer blanks, to an analytical laboratory licensed by the State of California for hazardous materials work. The samples shall be analyzed for Total Petroleum Hydrocarbons (diesel) and BTX&E (Benzene, Toluene, Xylene, and Ethyl Benzene). 6). Prepare a technical report for each phase of work being performed, that documents all of the activities of that phase and discusses the data collected, and integrates the data with previously collected data. The report will include an executive summary and will have analytical results as well as analytical summaries. Graphical representations and geologic cross sections (if appropriate) will also be included and will be signed by a professional pursuant to the DEH guidelines. 7). Meet with DEH personnel at least once if required, to discuss any report deficiencies, correct any report deficiencies and submit a revised report to the appropriate agencies.
