=i I <br /> Mr.Binayak Acharya !j Project 22074-001.001 <br /> November 3, 1995 j <br /> Page 2 <br />' ii <br /> � <br /> Excavation of the oil/water separator was performed in Maly or June.1986. Three samples <br /> (S#1, S#2, and S#3) from the stockpiled soil were collected and analyzed for total <br /> hydrocarbons, purgeable aromatics, and purgeable halocarbons in June 1986. Table 2 <br /> presents the results of the stockpile soil samples. Petroleum hydrocarbons (up to 2,200 <br /> mg/kg, S#3) and low concentrations of purgeable aromatics and halocarbons were detected <br /> f in each of the samples. {� <br /> Because excavation occurred after the sampling of boring B-7, it is likely that the HBHCs, <br /> hydrocarbons, and unidentified compound detected in the samples from boring B-7 were <br /> removed. <br /> !i <br /> i <br /> Please call if you have questions. <br /> Sincerely, _ I <br /> I <br /> EMCON <br /> Peter T.
