AdvancedGeo <br />Environr-nental <br />05Mg. <br />01 August 2018 <br />AGE Project No. 12-2169 <br />Page 3 of 3 <br />o Polynuclear aromatic hydrocarbons (PAHs) in accordance with EPA <br />Method 8270. <br />Laboratory reports of soil analysis, testing methods, laboratory quality assurance/quality <br />control (QA/QC) reports, and sample chain of custody documentation will be presented <br />in a report of findings and recommendations. <br />3.3. EQUIPMENT DECONTAMINATION/WASTE MANAGEMENT <br />All sampling tools will be thoroughly rinsed with clean water after being washed with a <br />solution of Alconox. All down-hole drilling equipment will be pressure washed prior to <br />starting each boring. Rinseate and soil cuttings generated during drilling and groundwater <br />sampling activities will be containerized in properly labeled, Department of Transportation <br />(DOT)-approved 55-gallon drums and stored on-site in an area lacking public access. <br />Disposal alternatives will be evaluated based on the results of soil analysis. <br />3.4. BORING ABANDONMENT <br />The soil boring will be permanently sealed to prevent vertical migration of potential <br />contaminants. The soil boring shall be abandoned by backfilling with Portland type II <br />cement grout from the total depth to surface grade. Any water displaced during the <br />grouting process will be routed and contained into a 55-gallon drum. The top three to six <br />inches of the boring abandonment will be completed flush to surface grade with concrete. <br />The EHD will be notified for grout inspection at least 48 hours prior to conducting grouting <br />procedures. <br />3.5. PREPARATION OF REPORT OF FINDINGS <br />A report documenting the soil boring and collection of soil samples will be prepared <br />following performance of field work and receipt of all applicable data. Conclusions and <br />recommendations will also be included, if applicable in the report. The report will be in a <br />format acceptable to the RWQCB and reviewed and signed by a California Professional <br />Geologist.
