auger flights, soil sampler, and drill rods will be steamed-cleaned prior to <br /> each boring, and the soil sampler will be cleaned after each sample is <br /> collected. <br /> The soil samples will be collected in brass liners. Immediately after the soil <br /> filled liner is removed From the sampler, the ends of the sample will be covered <br /> with foil and Lhen capped. The sample will then be labled and then be secured <br /> in either a jar or a plastic bag. The secured container will be labeled with <br /> the sample number, time, date, boring number, and depth of sample. The samples <br /> will be kept in an ice chest and delivered to the analytical laboratory within <br /> 24 hours. The soil boring number, depth of the sample, time of sample <br /> collection, sample number, and description of the soil will be entered into a <br /> i <br /> log book. <br /> Diesel residues will be analyzed by methodology following a modified EPA method <br /> 8015 wing a gas chromatograph with a flame ionization detector (GC-FID). <br /> Aromatic Volatile Organics will be analyzed by EPA method 8020 using a gas <br /> chromotograph with a photo€onization detector (GC-PID) or by equivalent methods. <br /> Quality Control-Quality Assurance samples will comprise 10% of the sample set. <br /> — — -- ---------------- --—Larry E: Fla 11 ------- <br /> California Registered Geologist 3956 <br /> 't <br /> -4- <br />
