GROUND WATER SAMPLING AND ANALYSIS <br /> Following the installation ofnew monitoring wells,groundwater monitoring and sampling activities <br /> will be conducted for all the monitoring wells on a quarterly basis for a minimum of one year(four <br /> sampling events);monitoring activities will include recording depth to ground water measurements <br /> and collection of ground water samples for laboratory analysis by a DHS-certified laboratory for the <br /> tanalytes noted in Section 3.2.Ground water sample collection protocols are described in Section 4.4. <br /> Laboratory reports for ground water analyses,testing methods,laboratory quality assurance/quality <br /> ' control(QA/QC)reports and sample chain of custody documentation will be presented in quarterly <br /> reports with findings and recommendations. <br /> ' 3.5. PREPARATION OF REPORT OF FINDINGS <br /> ' Following the advancement of soil borings and/or each ground water monitoring event,a report will <br /> be prepared presenting the findings. Each report will include a description of work performed and <br /> ' the results of sampling and analysis. Laboratory reports for soil analysis, ground water analyses, <br /> testing methods,laboratory quality assurance/quality control(QA/QC)reports,and sample chain of <br /> custody documentation will be presented in the quarterly report.Conclusions and recommendations <br /> ' will also be included,if applicable.The report will be in a format acceptable to the CVRWQCB,and <br /> will be reviewed and signed by a California Registered Geologist. <br /> ' 4.0. FIELD PROCEDURES <br /> ' All field procedures will be overseen by an AGE representative under the supervision of a California <br /> Registered Geologist. Procedures for advancement and sampling of soil borings and, if necessary, <br /> well installation, well development and sampling, are described below. <br /> 1 <br /> 4.1. SOIL BORING ADVANCEMENT AND SAMPLING <br /> ' Four soil borings will be advanced at the site to depths of approximately 40 feet bsg utilizing a truck- <br /> mounted hollow-stem drill rig with 8.25-inch diameter hollow-stem augers. Soil samples will be <br /> collected continuously from the boring near the former UST location; samples will be collected at <br /> five-foot intervals in all other borings. <br /> ' Relatively undisturbed soil samples will be collected in each of the borings using a California <br /> modified split-spoon sampler(continuously-sampled boring)and with the split-spoon sampler fitted <br /> t <br /> Advanced Geo Environmental,Inc. <br /> 1 <br />
