FINDINGS <br /> Soil descriptions and ground water elevation were determined from field data Hydrocarbon-impact <br /> 1 to soil and ground water was inferred from laboratory analysis of the soil and ground water samples <br /> 1 61 ANALYTICAL RESULTS OF GROUND WATER SAMPLES <br /> Based on analysis of the July 2006 ground water samples,TPH-g,BTEX and fuel additives were not <br /> 1 detected ground water samples collected and analyzed The down gradient monitoring well MW-2, <br /> and the cross gradient monitoring well MW-4 were no detect for hydrocarbons, additionally well <br /> RW-I was non detect for hydrocarbons, adjacent to the former UST area <br /> 1 1 of water samples are summarized in Table 5 A co of the laboratory reports <br /> The analytical results p copy ry p <br /> (CTEL ProjectNo CT214-0607152),quality assurance/quality control(QA/QC)reports, and chain <br /> of custody forms are included in Appendix D GeoTracker confirmation pages of the submitted <br /> laboratory electronic deliverable format (EDF) files are included in Appendix E <br />.0 <br /> Advanced GeoEnvironmentai,Inc <br />
