• Conclusions From Tank Removal Soil Sample Analysis The concentration of TPHd is the highest under the south end of the 12000-gallon diesel tank.Lower concentrations were found to decline toward the north end of the tank. Most likely a spill occurred near the south end of the 12000-gallon diesel tank. REPORT OF FINDINGS FROM THE MW41 aka UST-1 Second Quarter Sampling Event Sampled 6113102 Water Sampling and Analysis Water samples from MW#1 were extracted by Del-Tech Geotechnical Support Services on 0611312002. The samples were transported under chain of custody to Sherwood Labs. Sherwood transported one portion of the sample to Castle Analytical Labs for analyses by EPA Method 8260 for 1,2 DCA and 1,2 DCE.Pump purge rates were one G.P.M.Depth to the water surface was 49.65' with a+/-4' stickup on the casing. The water table at the time of sampling was about 45'below the surface. TPHd and BTEX were analyzed by EPA Methods M8100 and 8020 by Sherwood Labs in house. • Findings from Sample Analysis Analysis by all of the above methods resulted in non-detect status for each of the analytes. Conclusions from this Groundwater Sample Analysis The laboritory results from this sample period are non-detect as were the results of the first two sets of water samples extracted from this monitoring well.The analysis of the groundwater samples from the 3/01/2002 were rejected due to the fear of contaminated samples. The groundwater elevation had risen two feet as of 3/01/2002 and the soil bore may have been contaminated by drill auger carry over Three out of a total of four groundwater samples have been analyzed as non-detect for all analytes. The author feels it is safe to conclude that the spill from the UST did not reach the groundwater. Conclusions From Soil Sample Analysis The first ten feet of the soil lithology is a very clean fine sand. The remainder of the soil profile is made up of much finer and less permeable silts and clays that are dense too very dense by blow count. The concentration of TPHd at twenty-five below the surface is 76 mg/Kg and less than 5 percent of the concentration of TPHd at twenty feet below the surface. With the source removed, it would seem very unlikely that a contamination plume will migrate to the depth of the water table. The monitoring well was installed in the middle of May when the water table should have been at' the highest level. The most likely groundwater contamination potential comes from a raise in the groundwater to within twenty-five feet below the surface. This possibility is very remote. During 2
