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 Bryan A. Stirrat&Associates (BAS, an affiliate of <br /> GeoLogic Associates [GLA]). Sampling and analyses were performed in general accordance <br /> with the RWQCB Order No. R5-2004-0159 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., a state-certified laboratory. <br /> Groundwater and surface water samples were analyzed for the list of routine parameters listed in <br /> WDR Order No. R5-2004-0159. Table 1 summarizes site monitoring parameters, analytical <br /> methods, sample bottle requirements, and holding times. Water quality samples were also <br /> analyzed in the field for turbidity, temperature, specific conductance, and pH and recorded on <br /> twell data sheets. Copies of the certificates of analyses and Chain-of-Custody records for the <br /> 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. .)was recorded. <br /> • Groundwater monitoring wells at the French Camp Landfill are equipped with dedicated <br /> bladder pumps. <br /> t 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 SAplansp06.doc <br /> Geologic Associates <br />
