23 February 2006 . AGE-NC Project No 04-1214 Page 3 of 4 103)to 7 3 (MW-101) Analytical results are summarized in the laboratory report (CTEL Project No CT214-0601044) included in Appendix C The data from the sampling events are summarized in Table 2 Also included are quality assurance/quality control (QAIQC) reports, and the chain of custody form 4.0. SUMMARY AND CONCLUSIONS Based on the data collected from the site investigation, AGE finds • The ground water flow direction was inferred to be west to somewhat northwest at a low hydraulic gradient north of well MW-101 • Dissolved chlorinated pesticides,herbicides,ammonia and nitrates were not detected in the ground water samples collected from the wells at Ripon Farm Service The pH values were in a range generally accepted as "normal" . The general lack of detection for the ammonia and nitrate in the four on-site monitoring wells, all completed within the first water bearing aquifer at the site, appears to indicate that Ripon Farm Service site is not a primary source for the regional nitrate detected in deeper-screened domestic wells, including the on-site drinking water well 5.0. RECOMMENDATIONS Based on the findings of the environmental activities recounted in this report and previous investigations, AGE recommends continuation of the quarterly ground water monitoring program, the next monitoring event is scheduled for April 2006 As documented by multiple domestic wells in the vicinity of Ripon with excessive nitrate concentrations, the regional nitrate-impact (regional plume)to the primary drinking water aquifer should be further investigated through additional sampling of off-site shallow monitoring wells and deeper-screened domestic wells 6.0.
