laboratory under contract to Forward. Samples were analyzed for the parameters stipulated in RWQCB Order No. R5-2003-0049. Table 2-1 summarizes site monitoring parameters, analytical methods, and monitoring frequency. Water quality samples were also analyzed in the field for dissolved oxygen,turbidity,temperature, specific conductance, and pH and recorded on well data sheets. The groundwater monitoring wells, surface water monitoring points, and leachate monitoring points were sampled in accordance with the sampling and analysis procedures detailed in Appendix B. The well data sheets, laboratory data, certificates of analyses, and chain-of-custody records for the sampling program are included in Appendix C. The laboratory analyses and field results for groundwater monitoring wells, lysimeter and leachate sampling stations are summarized in Tables 2-2 through 2-8. 2.1.2 QA/QC Results The quality assurance/quality control(QA/QC)program completed for the third quarter 2007 water quality monitoring event included analyses of five field blanks, two trip blanks, two equipment blanks, and five laboratory method blanks. The trip, field, equipment, and laboratory method blanks were analyzed for volatile organic compounds (VOCs)by EPA Method 8260. The results of the QA/QC program indicate that chloroform and/or methylene chloride were detected in several of the QA/QC field, equipment, and laboratory method blanks; and benzene, carbon disulfide, ethylbenzene, toluene, and xylenes were detected in one of the equipment blanks during the third quarter 2007 monitoring event. Review of the primary sample results indicates that ethylbenzene, toluene, and xylenes were detected in the primary samples collected from the Forward Unit. Since these VOCs were detected in the equipment blank sample from the pump used to also sample well MW-17, there were flagged as suspected field/laboratory contaminants. Review of third quarter 2007 sampling dates and laboratory analytical certificates indicates that the laboratory analyses were completed within required holding times. Based on the results of the laboratory QA/QC analyses, it is concluded that the laboratory data generated for the third quarter 2007 monitoring period are generally acceptable. 2.1.3 Groundwater Elevations and Contours Prior to purging and sampling, each well was sounded for water depth using a weighted electronic sounder to an accuracy of 0.01 foot, and the static water level was recorded on a Well Data Sheet(Appendix C). The groundwater elevations were calculated for each well by subtracting the depth-to-water measurement from the top-of-casing reference elevation. The current groundwater elevation data for the Forward Unit is summarized in Table 2-3. The groundwater elevation data obtained during the third quarter 2007 monitoring period were used to generate the groundwater elevation contour map shown on Figure D:\2007_0043\For"rdAustin_sum07.doc _.- 4 GeoLogic Associates
