1 <br /> I <br /> 03 January 1996 <br /> AGE-NC Project No. 95-0197 <br /> Page 3 of 4 <br /> Soil samples will be collected at five-foot intervals beginning at 15 feet below site grade (bsg) using <br /> a Geoprobe soil sampling assembly and four 1.125-inch diameter brass sleeves. The second brass E <br /> sleeve will be removed and the ends covered with Teflon tape or aluminum sheets, sealed with plastic <br /> end caps, secured with,tape, and immediately placed in a chilled container for transportation to a <br /> State-certified laboratory. Each sample sleeve will be labeled with the following: boring location, a <br /> depth, time, date and sampler's initials. <br /> Soils will be described using the Unified Soil Classification System (USCS). Soil sample descriP tions <br /> and PID screening results would be summarized on boring logs�'prepared for the final report. <br /> Grab ground water samples will be collected from selected probings using a Geoprobe water sampling t <br /> assembly and a peristaltic pump. The samples will be collected in 40-m1 VOA vials and 1-liter amber <br /> bottles and placed-in a chilled container for transportation to 'a State-certified laboratory. Each ; <br /> sample will be labeled with the following: boring location, depth, time, date and sampler's initials. <br /> 3.2. EQUIPMENT DECONTAMINATION <br /> i <br /> All sampling tools and brass sleeves used for sample collection will be thoroughly rinsed with clean <br /> water after washing' with a solution of Alconox. All Geoprobe rods will be cleaned prior to <br /> advancement in each"probing. <br /> 3.3. LABORATORY ANALYSIS <br /> Selected soil samples will be analyzed for total petroleum hydrocarbons quantified as gasoline (TPH- <br /> g), total petroleum hydrocarbons quantified as diesel (TPH-d), and volatile aromatics (benzene, <br /> toluene, ethyl benzene, and xylene: BTE&X) in accordance with EPA methods 8015, 8015M and <br /> 8020, respectively. <br /> Grab ground water samples will be analyzed for TPH-g, TPH-d and BTE&X in accordance with EPA <br /> methods 5030/8015in and 602. <br /> 4.0. PROCEDURES <br /> 4.1. COLLECTION OF SOIL SAMPLES <br /> For collection of soil'samples, the following procedures will be performed: <br /> 1. Notify the San Joaquin County PHS-EHD 48 hours prior to commencement of any work. <br /> 5 <br />
