21 September 2005 <br /> AGE-NC Project No. 05-1282 <br /> Page 5 of 7 <br /> GRAB GROUND WATER COLLECTION AND ANALYSIS <br /> Although ground water was initially encountered in the borings at depths between 15 and 25 feet bsg, <br /> the water rose to static levels between 6.5 and 19 feet bsg.With the exception of borings B-10,B-13 <br /> to B-15 and B-18,a`grab'ground water sample was collected from each boring by lowering a length <br /> of polyethylene tubing with a ball valve down a temporarily installed one-inch diameter PVC casing <br /> with a 5-foot long 0.010-slotted well screen at the base. Each ground water sample was transferred <br /> into laboratory-supplied,40-m1 volatile organic analysis(VOA)vials containing 0.5 ml hydrochloric <br /> acid(18%)as sample preservative and an amber one-liter glass container(except for the sample from <br /> B-5). After collection, the samples were properly labeled, placed in a chilled container and <br /> transported under chain of custody to CTEL. The samples were analyzed for one or more of the <br /> petroleum hydrocarbon products listed above. <br /> FINDINGS <br /> Field observations detected the presence of volatile organic compounds(utilizing the OVM)above <br /> background levels or petroleum hydrocarbon-like odors in soil samples collected from borings B-1 <br /> (at 5 feet, 10 feet, 15 feet and 20 feet),B-7 (at 15 and 20 feet),B-8 (at 20 feet), B-15 (at 5 feet, 10 <br /> feet and 15 feet), and B-16, B-17 and B-18 at 5 feet bsg. <br /> Eight of seventeen selected soil samples submitted for analysis had analytes detected above <br /> laboratory reporting limits. Maximum concentrations of the analytes were 13,000 milligrams per <br /> kilogram(mg/kg)TPH-g in B-1-15,43,000 mg/kg TPH-d in B-14-15 and 13,000 mg/kg toluene in <br /> B-1-15. <br /> Nine of thirteen ground water samples submitted for analysis had analytes detected above laboratory <br /> reporting limits.Maximum concentrations of the analytes were 6,900,000 micrograms per liter(µg/1) <br /> TPH-g in the water from B-1, 5,300,000 µg/1 TPH-d in the water from B-7,6,800,000 µg/1 toluene <br /> in the water from B-1 and 120,000 4-Methyl-2-pentanone(MIBK)in the water from B-1. <br /> No other target analytes were detected at or above laboratory reporting limits in the samples <br /> submitted for analysis. The analytical results are summarized in Tables 1 and 2. Copies of the <br /> laboratory reports (CTEL Project Nos. CT214-0508025, 0508036,0508044 and 0508051), quality <br /> assurance/quality control(QA/QC)reports and chain of custody forms are included in Appendix B. <br /> SUMMARY AND CONCLUSIONS <br /> Soil and ground water results indicate three primary areas of concern at the site: <br /> Advanced GeoEnvironmental,Inc <br />
