ANALYTICAL RESULTS OF GROUND WATER SAMPLES <br />Four ground water samples were analyzed by CTEL for the chemical constituents referenced in <br />Section 2.5.. No VOCs, solvents, fuel additives or components were detected at or above laboratory <br />reporting limits. <br />The analytical results of ground water samples are summarized in the laboratory report CTEL Project <br />No. CT214-0408136, with QA/QC reports and chain of custody forms included in Appendix F. <br />4.0. SUMMARY AND CONCLUSIONS <br />Based on the data collected from the site, AGE concludes: <br />Three major sediment units were found at the site, dry silty sand in the upper vadose zone, <br />dry to moist silty and minor clay units, with localized sandy silt in the lower vadose zone and <br />damp to saturated poorly graded sands at the water table and in the primary aquifer at the <br />site. <br />Ground water was encountered at approximately 51 feet bsg. Ground water flow was south <br />across the site at a gradient of approximately 0.0028 ft/fl. <br />No target analytes were detected in soil and ground water samples collected at the site. <br />5.0. RECOMMENDATIONS <br />Based on the findings of the environmental activities recounted in this report, AGE recommends: <br />Continuation of the quarterly monitoring program; the next monitoring event should be <br />performed in November. <br />Conducting a receptor survey of domestic water wells within 2,000 feet of the site. <br />Advanced GeoEnvironmental, Inc.
