04 February 2001 • AGE-NC Project No 95-0104 Page 3 of 3 3 2 ANALYTICAL RESULTS OF GROUND WATER SAMPLES No analytes were detected at or above laboratory reporting limits in the ground water samples collected from the site Analytical results of the ground water samples are summarized in Table 2 The laboratory reports (McCampbell Analytical Inc Lab I D No 87464 through 87470) and cham-of-custody form are presented in Appendix B I 4.0. DISCUSSION AND CONCLUSIONS IBased on data collected during the December 2001 sampling event, AGE concludes • The ground water flow direction is inferred to be generally towards the northeast under an average hydraulic gradient of 006 feet/feet Figure 3 illustrates the contoured ground water elevations • No analytes were detected at or above laboratory reporting limits in the ground water samples collected from the site I• 5.0. RECOMMENDATIONS Based on the findings of this investigation, AGE recommends one quarterly monitoring event be conducted at the site to confirm the results of the fourth quarter 2001 monitoring event A monitoring event was performed on 30 January 2002 with concurrence of the San Joaquin County Environmental Health Department If concentrations remain below detection limits,AGE recommends the site be considered for closure 6.0. LIMITATIONS Our professional services were performed using that degree of care and skill ordinarily exercised by environmental consultants practicing in this or similar localities The findings were based upon analytical results provided by an independent laboratory Evaluations of the geo logic/hydro geologic Iconditions at the site for the purpose of this investigation are made from a limited number of available data points (I e ground water samples) and subsurface conditions may vary away from these data points No other warranty, expressed or implied, is made as to the professional Irecommendations contained in this report • Advanced GeoEnvironmental,Inc I
