rr (M I \l • cubic yards of soil were removed from the former UST location A soil sample was reportedly collected by RAMCON and analyzed for TPH from a depth of 18 feet below ground surface (bgs) This sample was reportedly submitted to an analytical laboratory for analysis and was reported to contain 1,300 mg/kg TPH A second soil sample was reportedly collected from 27 feet bgs that was analyzed and reportedly was below analytical method detection limits (Applied GeoSystems, 1988) No laboratory analytical report or map of sample location is available The excavation was reportedly backfilled with clean soil to grade The petroleum hydrocarbon contaminated soil was stockpiled and aerated in accordance with verbal instructions by PHSEHD The soil was subsequently tested in 1994 by Mr Dana Booth by composite soil sampling and the samples submitted to a state licensed analytical laboratory The soil was reported to contain no detectable VOC's Subsequently, the sod has been spread on the property 6. IDENTIFICATION AND ESTIMATED QUANTITY OF MATERIAL RELEASED: Gasoline, the quantity is unknown 7. PREVIOUS WORK: Based on the soil sampling and laboratory analytical results during the UST removal, PHSEHD issued an Unauthorized Release Report (UAR) and directed the property owner, Mr Carl Yearing to conduct a Site Assessment investigation • to determine the vertical and horizontal extent of gasoline and other volatile organic compounds released into the soil and groundwater beneath the site Litigation apparently occurred from 1988 to 1991 over the responsibility of who should conduct and pay for the investigation and remediation costs RAMCON Inc retained Applied GeoSystems, Inc to investigate soil and groundwater contamination at the site during August, 1988 In August 1988, Applied GeoSystems drilled four borings (SB-1 to SB-4, Figure 3) After drilling, Applied GeoSystems converted SB-4 into a 2-inch diameter shallow-groundwater monitoring well (PT- MW-1) Soil samples were collected at five foot intervals from each of the soil borings and field screened for volatile organic compounds using a photoionization detec for (PID) Relatively low but positive PID readings were recorded by Applied GeoSystems on the log of soil boring for SB-3 throughout most of the boring The highest PID reading from SB- 3 was recorded at a depth of 20 feet bgs Although the upper portion of the soil boring (0 to approximately 25 feet bgs) of SB-4 recorded background level PID readings, the highest recorded PID reading was recorded in boring SB-4 at approximately the groundwater surface(40 feet bgs) None of the soil samples were reportedly submitted for quantitative analysis by a state certified laboratory Soil boring SB-4 was advanced to approximately 60 feet bgs and completed as PT-MW-1 Prior to development of Mam\C%nvuonmentaMarmarTexaco\Workplan\042003 wpd 6
