t` <br /> i <br /> 9/27/96 EHD letter after the TRC meeting that requested further <br /> information. <br /> 03/20/02 EHD received a Site Closure Report dated August 10, 1998 <br /> prepared by Emcon. The report included a 1990 well survey <br /> and a mass calculation. <br /> The survey identified within % mile radius 10 industrial <br /> wells and 1 domestic well upgradient (north) of site, and 2 <br /> industrial well cross-gradient (west) . The survey <br /> identified the out of service municipal well No. 72 located <br /> V. mile east of the site, and a domestic well M mile south of <br /> the site. Emcon stated most of these wells are not in <br /> operation due to poor water quality in the area. <br /> Emcon calculated a total mass of 1,411 lbs of diesel in the <br /> soil, and a mass of 15.25 gallons of diesel in groundwater <br /> using 1991 data, and 26.5 gallons in groundwater using 1995 <br /> data. 1995 data covers a larger area than 1991 data. <br /> 6/26/02 EHD & RWQCB staff discussed the site and decided that one <br /> more quarter of groundwater sampling would be required. <br /> 08/14/02 EHD received Groundwater Monitoring Report dated August 14, <br /> 2002 . Monitoring wells 4, 5 and 6 were sampled for, two <br /> consecutive quarters. Analytical results of All wells were <br /> less than 50 µg/l of diesel except for one sample (July 2002 <br /> MW-5 groundwater sample result was 290 pg/l of diesel) . <br /> Water is about 15 feet bsg. Gradient has been east to. <br /> southeast since August 1992. <br />
