— 02 November 1999 AGE-NC Project No. 99-0628 Page 5 of 8 and line soil sample analytical results are presented in Tables 1, 2 and 3. The laboratory analytical report is presented in Appendix A. Dry well and line soil sample analytical results are detailed below. 5.2.1. Benzene, Toluene, Ethylbenzene and Total Xylenes — Toluene was detected in samples DWI-28 and DW2-28 at concentrations of 0.029 mg/kg and 0.007 mg/kg. Xylenes were detected in the three dry well samples at concentrations ranging from 0.018 y mg/kg to 0.10 mg/kg. There were no reported detections of benzene or ethylbenzene. Results of BTEX analysis are summarized in Table 1. 5.2.2. Total Petroleum Hydrocarbons TPH-g was detected in each dry well sample at concentration ranging from 1.8 mg/kg to 15 mg/kg. TPH-d and TPH-Ino were detected in each dry well sample at concentrations ranging from 650 mg/kg (TPH-d, DW3-28) to 10.000 mg/kg (TPH-mo, DWI-28). No detections of TPH-g. TPH-d or TPH-mo were reported in sample B 1-5. Results of TPH analysis are summarized in Table 1. 52.3. Volatile Organic Compounds A total of twelve target analytes were detected in the three dry well samples. Eleven VOCs were detected in sample DWI-28 at concentrations ranging from 17 ,ug/kg (ethyl benzene) to 160 ,ug/kg (naphthalene). Ten VOCs were detected in sample DW2-28 at concentrations ranging from 8.7 _ icg/kg (sec-butyl benzene) to 310 ug/kg (1,2,4-trimethylbenzene). Four VOCs were detected in sample DW3-28 at concentrations ranging from 7.8 ,ug/kg (toluene) to 14 µg/&-g (1,2,4- trimethylbenzene). Detectable concentrations of VOCs were not reported in sample B1-5. Results of the VOC analysis are summarized in Table 2. 5.2.4. Semi-Volatile Organic Compounds Only one SVOC target analyte, bis(2-ethylhexyl) phthalate, was reported in sample DWI-28 at 14 ug/kg. No detected concentrations of SVOCs were reported in samples DW2-28, DW3-28 or BI-5. Advanced GeoEnvironmental,Inc.
