Copies of the laboratory <br />reports (CTEL Project Nos. CT214-1101105 and -1101106) are included as Appendix A. <br />CONCLUSIONS <br />Based on the analytical results of the Phase II, AGE concludes: <br />Soil samples collected down-gradient of the leaking compressors were non-detect <br />for constituents of concern, indicating an absence of gross contamination. <br />Ground water impact was reported in the two grab ground water samples collected <br />from the eastern, down-gradient most point, of the site. It is unclear if the impact is <br />a result of on-site or off-site sources. Contaminants reported in the ground water <br />include solvents and gasoline range organics. <br />Advanced GeoEnvironmental, Inc.
