V� V <br /> LEEDSHILL•HERKENNOFF. INC. <br /> Ms. Jeanne M. Zolezzi SUBJECT TO ATTORNEY/CLIENT PRIVILEGE <br /> January 16, 1990 CONTAINS ATTORNEY WORK PRODUCT <br /> Page 2 <br /> Task 2: Laboratory Tests <br /> Analyses of soil and water samples will be made by Superior Analytical Laboratory, <br /> a state certified hazardous waste laboratory. The samples will be analyzed for <br /> benzene, toluene, xylene, and ethylbenzene (BTX&E) and total petroleum <br /> hydrocarbons as gasoline (fPH), under standard laboratory turnaround times. <br /> Initially soil samples collected from depths of 10, 20, and 30 feet in each boring will <br /> be analyzed for BTX&E constituents. If better vertical definition is required, a cost <br /> allowance to perform a total of 2 additional analyses from intermediate depths (i.e., <br /> 15, 25, etc.) has been made within this budget. <br /> Task 3: Prepare Report <br /> Following the site investigation and receipt of the laboratory test results, a brief <br /> letter report will be prepared setting forth the results of the investigation. The report <br /> will document investigative methods; results of laboratory tests; and <br /> recommendations. <br /> COST FOR BASIC ENGINEERING SERVICES <br /> LH has estimated that Basic Engineering Services described in Tasks 1 through 3 above <br /> will cost approximately $26,900. LH will conduct all work on a time-and-materials basis <br /> with services provided in accordance with our current Standard Schedule of Fees, which <br /> is attached. Costs for LH subconsultants will be billed at cost plus 10 percent. This offer <br /> is good for thirty (30) calendar days from January 15, 1990, and is contingent on Regional <br /> Water Quality Control Board and Public Health Services San Joaquin County's acceptance <br /> of the scope of work outlined above. The tabulation below presents a breakdown of <br /> these anticipation costs: <br /> Estimated Phase I Costs <br /> Professional Services $14,500 <br /> Drilling/Sampling/Monitoring $12,700 <br /> Well Installations <br /> Laboratory Analyses $ 1,700 <br /> $28,900 <br />
