Page 10 Cabral-McAdams Property October 16,2006 Job No. 1828-092.02 The two-part composite samples of surface soils from the locations S9 through S 12 also were analyzed for TPH as gasoline, TPH as motor oil, and TPH as diesel, and BTEX. Only TPH as motor oil was identified within these samples at concentrations above laboratory reporting limits. TPH as motor oil was detected at concentrations of 280 mg/kg (for the composite sample from locations S9 and S10) and 1,300 mg/kg (for the composite sample from locations S 11 and S 12). Area B Surface soil samples collected at locations S13 through S16, and S33 through S35, as well as the one foot deep soil samples collected from locations S13 and S14 were analyzed for lead and arsenic. Concentrations of lead identified in the soil samples collected from these locations ranged from 8.0 milligrams per kilogram (mg/kg) to 120 mg/kg. Arsenic concentrations identified in these samples ranged from less than 2.0 mg/kg to 12 mg/kg. The surface soil samples collected at locations S13 and S14 were laboratory combined into a two-part composite sample for analysis for organochlorinated pesticides. Surface soil samples from locations S15 and S32 through S35, and soil collected at a depth of one foot at locations S13 and S14 also were analyzed for organochlorinated pesticides. In general, concentrations of organochlorinated pesticides were not detected in any of the composite surface soil samples at concentrations above laboratory reporting limits with the exception of 4,4'-DDE, 4,4'-DDD, 4,4'-DDT, which were detected in the composite sample (locations S13 and S14) at concentrations of 0.290 mg/kg, 0.30 mg/kg, and 2.8 mg/kg, respectively. Analysis of the one foot soil samples collected at locations S13 and S14 did not reveal any organochlorinated pesticides at concentrations above laboratory reporting limits. Chlordane and/or 4,4'-DDE, 4,4'-DDD, 4,4'-DDT were detected in the surface soil samples collected from Area B at concentrations well below established regulatory agency screening levels. A two-part composite sample of surface soils from the locations S 13 and S 14 and surface soil samples from locations S15 and S16 also were analyzed for one or more of the following: TPH as gasoline, TPH as motor oil, and TPH as diesel, and BTEX. TPH as motor oil was detected at a concentration of 27 mg/kg in the two-part composite sample collected from locations S13 and S14, and at a concentration of 1,100 mg/kg at location S15. Area C Surface soil samples collected at locations S17 and S29 through S31, as well as the one foot deep soil samples collected from location S17 were tested for lead and arsenic. Concentrations of lead identified in the soil samples collected from these locations ranged from 3.4 mg/kg to 270 mg/kg; arsenic concentrations identified in these samples ranged from less than 2.0 mg/kg to 11 mg/kg.
