September 13, 1995. I. �H <br /> Page 3 G <br /> t <br /> xylenes (BTEX,compounds), total petroleum hydrocarbons as diesel <br /> (TPH-d), oil and grease, volatile organic compounds (VOCs), semi <br /> E -volatile organic'compounds (SVOCs), and ICAP metals including <br /> cadmium, chrorium, lead, nickel, and zinc (ICRP metals). <br /> FINDINGS :i I <br /> E Subsurface Conditions <br /> Soils underlying the site encountered.during drilling consisted primarily of interbedded <br /> clayey silt, sandy silt, silt,:!silty sand, and sand to the total depth explored of <br /> approximately 60.5 feet b`gs.! Grbundwater was first encountered at approximately 40 to <br /> 44 feet bgs in the clayey and sandy silt and silty sand. <br /> Groundwater was encountered and stabilized at a depth of approximately 42 to 44 feet <br /> bgs (2.43,to 3.40 feet MSL)',in the wells installed during the investigation. Groundwater <br /> elevation data; calculated,f-drn data collected on August 2, 1995, indicate that"ground- <br /> water flow beneath the site is to the southwest at an approximate gradient of 0.006 ft/ft. <br /> Groundwater elevation and gradient data, and flow direction are shown on Figure 2. I <br /> h, <br /> Soil Analytical Results <br /> i. <br /> Results of soils analyses indicate''that soil samples were non detect f �I ical <br /> p or all analyti <br /> parameters with the exception of several ICAP metals. Soil samples from Weli MW-3 <br /> (located near the waste oil tank)detected metals at concentrations ranging from 4 to. <br /> 24 ppm in soil samples collec'ted''at 5 and 10 feet bgs. The results of VOC and SVOC i <br /> analyses from soil samples collected at 5 and 10 feet bgs from Well MW-3 were non- <br /> detect. Soil analytical data are presented in Table 1. <br /> I� <br /> Groundwater Analytical Results P, <br /> Results of groundwater analyses.indicate that all groundwater samples were non-detect <br /> for all analytical parameters with''the exception of several total and dissolved metals and <br /> the VOC ietrachloroethene. Tetrachloroethene was detected in Well MW-3 at-'a <br /> concentration of 6 parts per billion (ppb). Groundwater elevation and analytical data are <br /> presented in Table 2. <br /> If there are any questions regarding the contents of this letter report, please call. <br /> 3201531 AUZEPO RT <br /> u. h ' <br />
