GRAB GROUND WATER SAMPLE COLLECTION AND ANALYSIS <br /> A grab ground water sample will be collected from soil boring and submitted for laboratory analysis. <br /> The grab ground water sample will be collected at the first encountered water-bearing zone utilizing <br /> hydropunch-equivalent sampling techniques. Grab ground water sample collection procedures are <br /> presented in Section 4.2. <br /> Groundwater samples will be analyzed by a State-of California..DHS-certified laboratory for the <br /> following constituents: <br /> • BTEX by EPA Method 8260B; and <br /> • TPH-d by EPA Method 8015 Modified. <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 a report <br /> with findings and recommendations: <br /> 3.4. SENSITIVE RECEPTOR SURVEY <br /> A sensitive receptor survey will be conducted to identify receptors whereby environmental and/or <br /> public health could potentially be threatened by the unauthorized release of petroleum hydrocarbons <br /> at the site. The survey will consist of a reconnaissance of the site and surrounding area, review of <br /> well completion reports on file with the Department of Water.Resources (DWR), and inquiries to <br /> the local water purveyor to identify sensitive receptors within 2,000 feet of the site, including . <br /> municipal wells,domestic'wells,monitoring wells,septic systems,surface water;and ground water. <br /> Advanced GeoEnvironmental,Inc., <br />
