2.0 FORWARD UNIT <br /> 2.1 WATER QUALITY MONITORING <br /> 2.1.1 Sampling and Laboratory Analyses <br /> During the third quarter 2010, depth-to-water measurements were recorded in the <br /> groundwater monitoring wells and all of the groundwater monitoring wells were sampled <br /> by Del-Tech Environmental Support Services (Del-Tech) between August 25 and 27, <br /> 2010. Surface water stations FSW-1 and FSW-2 were reported dry on August 26, 2010. <br /> The lysimeters were checked for soil-pore liquid on August 25, 2010, and Del-Tech <br /> reported that all lysimeters were dry. Of note, lysimeters LY-E1B, LY-E2B, D-93B, <br /> WMU-DO1, WMW-D02,WMU-D02 (pan), and FU-03 could not be located or have been <br /> buried, while lysimeters LY-E 1 A and LY-E2A were reported to be plugged. <br /> Samples were collected by Del-Tech Geotechnical Support Services(Del-Tech) from <br /> each sample point containing sufficient liquid and submitted to TestAmerica Laboratories <br /> (TestAmerica) of Buffalo, New York, a state certified laboratory under contract to <br /> Forward. During the third quarter 2010 monitoring period, samples were analyzed for <br /> the routine monitoring parameters stipulated in RWQCB Order No. R5-2003-0049. <br /> Table 2-1 summarizes site monitoring parameters, analytical methods, and monitoring <br /> frequency. Water quality samples were also analyzed in the field for dissolved oxygen, <br /> turbidity, temperature, specific conductance, and pH and recorded on well data sheets. <br /> The groundwater monitoring wells and leachate monitoring points were sampled in <br /> accordance with the sampling and analysis procedures detailed in Appendix B. The well <br /> data sheets, laboratory data, certificates of analyses, and chain-of-custody records for the <br /> sampling program are included in Appendix C. The laboratory analyses and field results <br /> for groundwater monitoring wells, surface water stations, lysimeter and leachate <br /> sampling stations are summarized in Tables 2-2 through 2-6. <br /> 2.1.2QA/QC Results <br /> The quality assurance/quality control (QA/QC)program completed for the third quarter <br /> 2010 water quality monitoring event included analyses of two field blanks, two <br /> equipment blanks, four laboratory method blanks, and one duplicate sample. The field <br /> and equipment blanks were analyzed for volatile organic compounds (VOCs)by EPA <br /> Method 8260 and method blanks were analyzed for all of the analytes included in the <br /> monitoring program. The results of the QA/QC program indicate that no VOCs were <br /> detected in any of the QA/QC blanks during the monitoring period. During the third <br /> quarter 2010 monitoring event, a duplicate sample was collected from well MW-22 and <br /> labeled DUP. As shown on Table 2-2, with the exception of total dissolved solids, the <br /> duplicate sample analyses yielded good correlation(within 5%) with the primary sample <br /> results. Review of third quarter 2010 sampling dates and laboratory analytical <br /> certificates indicates that with the exception of hexavalent chromium and nitrate as <br /> nitrogen sample collected from well MW-1, the laboratory analyses were completed <br /> within required holding times. Review of the historical data indicates that the current <br /> D:\2010 0013\FA 3Q 10.doe <br /> 4 <br />
