r � • <br />. May 12, 1988 <br /> Page Two <br /> r <br /> Proposal <br /> The proposal is to do preliminary drilling of about 5 <br /> r boreholes to assess the depth and spread of the contamination. <br /> It is not planned to extend the borings to groundwater if the <br /> contamination is shallow. <br /> If contamination is not shallow, then borings 3 , 6 & 7 would <br /> be extended 20 '+ into groundwater . Groundwater is estimated to <br /> N be 80 feet deep. Groundwater slope is unknown at this time but <br /> will be investigated prior to drilling. <br /> Wells <br /> There are many wells in the area as shown on the attached <br /> I map. There is one well on the Pacific Bell site and one at the <br /> Fire Station across Ashley Road. If possible, these wells will <br /> be used to determine groundwater slope in place of Monitor Wells <br /> #6 and 7 . <br /> Laboratory Analysis <br /> Soil and water samples will be analyzed for TPH, BTX & E. <br /> Proposed start date is June 1, 1988. <br /> r If you have any further questions or require additional <br /> information, please do not hesitate to contact me. <br /> Sincerely, <br /> -/James Elder, R.E. <br /> M <br /> I <br /> 1 <br />
