SAMPLING AND ANALYSIS PLAN <br /> Water quality monitoring and sampling for the French Camp Landfill located within the Central <br /> Valley RWQCB Region was conducted by ATC Associates (ATC). Sampling and analyses were <br /> performed in general accordance with the RWQCB Order No. R5-2007-0046 issued specifically <br /> for the site. A brief summary of the protocols for sample collection is presented below. <br /> Chemical analyses were performed by BC Laboratories Inc. which is a state-certified <br /> laboratories. Groundwater and surface water samples were analyzed for the list of routine <br /> parameters listed in WDR Order No. R5-2007-0046. Table 1 summarizes site monitoring <br /> parameters, analytical methods, sample bottle requirements, and holding times. Water quality <br /> samples were also analyzed in the field for turbidity, temperature, specific conductance, and pH <br /> and recorded on well data sheets. Copies of the certificates of analyses and Chain-of-Custody <br /> records for the samples collected this quarter are included in Appendix C. <br /> Groundwater Sampling <br /> The sampling protocols listed below were generally followed during groundwater sampling <br /> operations: <br /> Upon arrival at the wellhead, each monitoring point was inspected for evidence of tampering <br /> and/or vandalism, and the well identification(I.D.)was recorded. <br /> . Prior to sampling the water quality meter will be calibrated daily using standardized solutions <br /> and recorded on a field calibration form. <br /> . The water level was measured directly using a weighted water-level indicator(sounder) to an <br /> accuracy of 0.01 foot. Prior to measuring the water level, the sounder was decontaminated <br /> using an Alconox® soap solution, followed by two rinses with deionized water. The wells <br /> were then sounded and the initial water level and the total depth of the well (if obtainable) <br /> were recorded on a Well Data Sheet. <br /> Groundwater Sampling Using Non-Dedicated Equipment <br /> • For wells with non-dedicated sampling equipment, up to three casing volumes (under optimal <br /> conditions)of water were purged prior to sampling. Based on the measured depth to water, <br /> the total depth of the well, and the known casing diameter, a well casing volume was <br /> calculated using the following equation: <br /> 1 <br /> DAFC_SAp1an2SA09.doc <br /> Geologic Associates <br />
