• <br /> location. Details of that work have not been reviewed. <br /> During investigative vork conducted in 9991 at Husky Crane, <br /> contamination was noted on the wall of the abuttin❑ <br /> BJJ Co. Surface drainage as shown on rhe USES topographic sheet , <br /> (Plate II, ) is generally west/southwest , from BJJ towards <br /> Hus1-y Crane. Based on limited data, the groundwater gradient <br /> is towards the east , away from Husky Crane. <br /> Although contamination was encountered during investigative work <br /> at Husky Crane at 6 bgl immediately adjacent to the BJJ Co. <br /> Property, the source of that contamination has not yet been <br /> determined. Until more information nas oeen obtained , our client <br /> doe, not wish to conduct in.•estigati%,e work offsite at this tiT:e. <br /> Therefore, the following workplan is restricted to the Husky <br /> Crane property only. <br /> WORKPLAN FOR SOIL INVESTIGATION <br /> NOTE: Bids are being received , and as soon as a drilling <br /> contractor has been selected , an application for a drilling <br /> permit, together with the appropriate fee, will be submitted to <br /> the County EHD. <br /> I . Move in properly l i censed auger-Mfr-i l F i ng rig egtii pped with <br /> clean hollow-stem flights & soil sampling equipment . <br /> 2. Place 6 auger holes at approximate locations as shown on <br /> Plate VII; auger holes A, B, C, D, & E are programmed to 75 bgl . <br /> It is planned to advance auger hole F to approkimately 50 ` bgl , <br /> is few feet into the estimated 1986 high water level , ) to <br /> determine if contamination reached that depth. <br /> 3. Soil samples will be taken at appro,imately 1 , and at 5 <br /> intervals from 5 ' bgl to deepest penetration. Sampling <br /> procedures will be conducted according to Tri-Regional and LUFF <br /> manual protocol under the direction of a Registered Geologist. <br /> Continuous soil sampling utilizing latch-type wireline equipment <br /> may be used instead of the conventional solid stem auger method <br /> if field conditions warrant. <br /> 4. Soil samples will be promptly sealed , labeled, and preserved <br /> on ice pending transport to FGL laboratory under proper chain of <br /> custody. <br /> 5. Soil samples will be tested for BTEK (EPA B020, ) TPH-G & <br /> TPH-D, (EPA 8015M, ) and total oil & grease (EFA 418. 1 . ) using <br /> detection limits as specified by San Joaquin Co.
