LFR Levine-Fricke <br /> ranged from 210 mg/l in the sample collected from monitoring well MW-1 to 463 mg/1 <br /> in MW-3. Analytical results for specific conductance for site monitoring wells ranged <br /> from 1,060 micromhos per centimeter (,umhos/cm; MW-1) to 1,740 ,umhos/em (MW- <br /> 3). Concentrations of nitrate detected in groundwater samples ranged from 0.90 mg/l <br /> in monitoring well MW-4 to 4.6 mg/I in monitoring well MW-2. Concentrations of <br /> sulfate in the groundwater samples ranged from 147 mg/l in the sample collected from <br /> MW-2 to 279 mg/l in the sample collected from MW-3. Concentrations of total <br /> organic carbon (TOC) detected in groundwater samples ranged from c 1.0 mg/l in <br /> monitoring well MW-1 to 2.3 mg/l in monitoring well MW-3. <br /> 4.3 Quality Control <br /> One duplicate groundwater sample collected from MW-1 on August 4, 2003 (labeled <br /> as DUP-01) was submitted to the laboratory as part of standard field quality <br /> assurance/quality control procedures. Analytical results for the duplicate groundwater <br /> sample revealed that reported concentrations were consistent with analytical results for <br /> the primary groundwater sample collected from MW-1. The relative percent difference <br /> of analytical results for the samples was within the accepted criterion of 40 percent. <br /> 5.0 SUMMARY OF 2003 ANNUAL RESULTS <br /> 5.1 Groundwater Elevations and Gradient <br /> Figures 3, 4, and 5 illustrate the groundwater elevation contours for the second <br /> through fourth quarters of 2003, respectively. Groundwater elevations and flow <br /> gradient directions varied seasonally, but consistently displayed a generally flat water <br /> table with a horizontal hydraulic gradient of 0.001 ft/ft toward the northwest. <br /> 5.2 Analytical Results <br /> Groundwater samples collected from monitoring wells MW-1 through MW-5 during <br /> the second through fourth quarters of 2003 were analyzed for parameters required by <br /> the RWQCB. Table 2 provides a summary of the analytical results and the laboratory <br /> analytical reports are presented in Appendix B. <br /> VOCs <br /> VOCs were not detected above laboratory reporting limits in samples collected from <br /> wells MW-1 through MW-5 during the second through fourth quarters of 2003. <br /> Page 6 TTFS QMR Q4-03.FINAL:JEE <br />
