2.0 FORWARD UNIT <br /> 2.1 WATER QUALITY MONITORING <br /> 2.1.1 Sampling and Laboratory Analyses <br /> During the second quarter 2010, depth-to-water measurements were recorded in the <br /> groundwater monitoring wells between June 2 and 4, 2010, and all of the groundwater <br /> monitoring wells were sampled by Del-Tech Environmental Support Services (Del-Tech) <br /> between June 2 and 10, 2010. Surface water stations were inspected and samples were <br /> collected from surface water station FSW-2 on June 3, 2010, while station FSW-1 was <br /> reported dry. All lysimeters were inspected and a vacuum was set on June 4, 2010. The <br /> lysimeters were checked for soil-pore liquid on June 24, 2010, and Del-Tech reported <br /> that all lysimeters were dry. Of note, lysimeters LY-E1B, LY-E213, D-9313, WMU-D0l, <br /> WMW-D02,WMU-D02 (pan), and FU-03 could not be located or have been buried, <br /> 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 BC Laboratories, Inc. <br /> (BC) of Bakersfield, California, a state certified laboratory under contract to Forward. <br /> During the second quarter 2010 monitoring period, samples were analyzed for the routine <br /> monitoring parameters stipulated in RWQCB Order No. R5-2003-0049. Table 2-1 <br /> summarizes site monitoring parameters, analytical methods, and monitoring frequency. <br /> Water quality samples were also analyzed in the field for dissolved oxygen,turbidity, <br /> temperature, specific conductance, and pH and recorded on well data sheets. The <br /> 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 2-7. <br /> 2.1.2 A/ C Results <br /> The quality assurance/quality control (QA/QC)program completed for the second quarter <br /> 2010 water quality monitoring event included analyses of four trip blanks,three field <br /> blanks,two equipment blanks, four laboratory method blanks, and one duplicate sample. <br /> The trip, field, and equipment blanks were analyzed for volatile organic compounds <br /> (VOCs)by EPA Method 8260 and method blanks were analyzed for all of the analytes <br /> included in the monitoring program. The results of the QA/QC program indicate that <br /> trace levels of acetone and chloroform were detected in one or more of the QA/QC <br /> blanks during the monitoring period. Review of the primary sample results indicates that <br /> neither acetone nor chloroform was detected in any of the primary samples collected <br /> during the monitoring period. During the second quarter 2010 monitoring event, a <br /> duplicate sample was collected from well MW-22 and labeled DUP. As shown on Table <br /> 2-2,with the exception of potassium,the duplicate sample analyses yielded good <br /> D:12010 00131FA_2Q10.doc <br /> 4 Geologic Associates <br />
