' 08 June 2005 i AGE-NC Project No. 95-0137 Page 4 of 6 • Total petroleum hydrocarbons quantified as gasoline and diesel (TPH-g and TPH-d, ' respectively) in accordance with EPA Method 8015 Modified; and • Benzene, toluene, ethylbenzene, and total xylenes (BTEX) and fuel oxygenates methyl tertiary-butyl ether(MTBE), tertiary-butyl alcohol (TBA), di-isopropyl ether(DIPE), ethyl tertiary-butyl ether(ETBE),tertiary-amyl methyl ether(TAME), 1,2-dibromoethane(EDB), and 1,2-dichloroethane (1,2-DCA) in accordance with EPA Method 8260B. 3.0. FINDINGS Ground water elevation, flow direction, and gradient were determined from field data collected on 04 May 2005;the contaminant impact to soil and ground water was quantified from laboratory data. 3.1. STRATIGRAPHY The soil boring advanced for well MW-9 was comprised of fines and,a ground water table within ' sands. Generally brown silts was'encountered from surface grade to approximately 25 feet.bsg. Tan to brown medium sand was generally encountered between 24 and 25 feet bsg. Silt was observed to ' the depth of the 34 feet in the soil boring MW9.A lower coarse sand at 35 feet was observed,which contains the water bearing unit for the s' e. The soil boring for well MW-10 was comprised of fines d and a ground water table withinwo lower sands. enerally brown silts were encountered from ' surface grade to approximately 25 feet bsg. Tan to brown medium sand was generally encountered sand between 24 and 25 feet bsg. Silt was observed to a the total depth of soil boring MW 10. / ' Organic vapor was not detected in the soil samples collected.No hydrocarbon-like odor was detected in any of the soil samples taken. The soil boring logs are provided in Appendix B; with organic vapor field measurements included on the boring logs. 3.2. ANALYTICAL RESULTS OF SOIL SAMPLES ' A total of seven soil samples were analyzed for the constituents listed in section 2.1.4.; no analytes were detected at or above laboratory reporting limits in the soil samples. Analytical results of soil samples are summarized on Tables 1 and 2.The laboratory reports(CTEL Lab Project.No.CT214-0504167),quality assurance and quality control(QA/QC)report and chain- of-custody forms are included in Appendix D.
