600 N Holt Road Project No.06304-01 Page 16 <br /> One groundwater sample duplicate will be collected and analyzed. The proposed analysis for the <br /> grab groundwater sample co-located at the boring 131 will be labeled B1-GW and the duplicate <br /> B1-GW-DUP is described in the table below: <br /> Table 2. Grab Groundwater Analysis <br /> ANALYTE MEDIA US EPA METHOD <br /> Or anochlorine Pesticides GW 8081A <br /> Temperature GW Field Based Meter <br /> Dissolved Oxygen DO GW Field Based Meter <br /> H GW Field Based Meter <br /> Oxygen Reduction Potential GW Field Based Meter <br /> Sampling will be performed using Level D personal protective equipment. Samples will be obtained <br /> with a decontaminated hand auger or shovel, or by direct push Geoprobe with continuous core rods <br /> advanced in the soil to appropriate depth(s) and transferred to clean laboratory supplied <br /> containers. Prior to collection of each soil and groundwater sample, all reusable equipment will be <br /> decontaminated in accordance with the following triple rinse method steps using Liquinox <br /> detergent: <br /> 1) Detergent wash <br /> 2) Tap water rinse. <br /> 3) Distilled water rinse. <br /> Samples will be placed immediately on ice and directly transported under chain-of-custody <br /> documentation to McCampbell Analytical Laboratories in Pittsburg, California. <br /> 4.2 Documentation <br /> Chain-of-custody records are used to document sample collection and shipment to laboratory for <br /> possible chemical analysis. All sample shipments for analyses will be accompanied by a chain-of- <br /> custody form. <br /> Each sample will be uniquely identified on laboratory-provided labels. Sample documentation will <br /> be maintained as follows: <br /> • Field notebook to include: <br /> o Sample I.D.numbers <br /> o Sample collection Date/Time <br /> o Latitude and Longitude determined from GPS unit. <br /> o Field staff <br /> o Any other appropriate details determined in the field. <br /> • Flags will be placed at each sample collection location. <br /> Petralogix Engineering,Inc. <br /> 26675 Bruella Road,Galt,Ca 95632 <br /> 12091-400-5729 <br /> U <br /> www.petralogix.com <br />
