SAMPLING AND ANALYSIS PLAN <br /> Water quality monitoring and sampling for the French Camp Landfill located within the <br /> Central Valley RWQCB Region was conducted by Del-Tech Geotechnical Support <br /> Services. Sampling and analyses were performed in general accordance with the <br /> RWQCB Order No. R5-2007-0046 issued specifically for the site. A brief summary of <br /> the protocols for sample collection is presented below. <br /> Chemical analyses were performed by BC Laboratories Inc. which is a state-certified <br /> laboratory. 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 <br /> quality samples were also analyzed in the field for turbidity,temperature, specific <br /> conductance, and pH and recorded on well data sheets. Copies of the certificates of <br /> analyses and Chain-of-Custody records for the samples collected this quarter are included <br /> in Appendix C. <br /> Groundwater Sampling <br /> The sampling protocols listed below were generally followed during groundwater <br /> sampling operations: <br /> • Upon arrival at the wellhead, each monitoring point was inspected for evidence of <br /> tampering 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 <br /> solutions and recorded on a field calibration form. <br /> • The water level was measured directly using a weighted water-level indicator <br /> (sounder)to an accuracy of 0.01 foot. Prior to measuring the water level, the sounder <br /> was decontaminated using an Alconox®soap solution,followed by two rinses with <br /> deionized water. The wells were then sounded and the initial water level and the total <br /> depth of the well (if obtainable) 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 <br /> optimal conditions)of water were purged prior to sampling. Based on the measured <br /> depth to water, the total depth of the well, and the known casing diameter, a well <br /> casing volume was calculated using the following equation: <br /> 1 Geo-Logic Associates <br />
