i <br /> SITE HISTORY <br /> On November 14 , 1989 the following tanks were removed from the <br /> site in accordance with the Tri-Regional Recommendations: <br /> 1 8 , 000 Gal. Unleaded Gasoline <br /> 1 5, 000 Gal . Super Unleaded Gasoline <br /> 2 5, 000 Gal . Unleaded Gasoline <br /> A total of 8 soil samples were taken , two under each tank and <br /> analyzed for TPH and BTX&E. The lab results previously <br /> reported varied from 1 . 9 to 3600 PPM for TPH. <br /> The excavation site was backfilled with the original soil plus <br /> soil from a new excavation. The site was then remodeled and <br /> placed back in service. <br /> • On Dec. 19 , 1989 an Electromagnetic Induction survey was <br /> conducted on the site to aid the investigation of the areal <br /> extent of the plume and to assist in locating the groundwater <br />' monitoring wells. <br /> Three wells were drilled in January 1990 to assess the <br /> groundwater. Our report of Feb. 9 , 1990 covered this work. <br /> Subsequently, we attempted to obtain groundwater samples at <br /> various times , however , the water table at the site fell <br />' below the bottom of the wells and has never recovered. <br /> Between March 30 and April 2 , 1992 we drilled three additional <br />! wells. This work was in our report of April 30 , 1992 . <br />' Between July 29th and August 3rd, 1993 , we drilled two additional <br /> wells. This work was in our report of August 24 , 1993 . <br /> RECENT FIELD WORK <br />' Page 3 <br />
