t <br /> STANDARD OPERATING PROCEDURES <br /> Collecting Organic Vapor Data From Soil Samples <br /> Soil samples from drill cuttings, soil piles or tank excavations are placed with <br /> minimal disturbance into pre-cleaned standard soil sample collection jars The jars <br /> are half filled, with the sample material being broken up to provide additional <br /> surface area for volatilization Aluminum foil is placed over the jar top, and then <br /> capped with the lid <br /> The jars are then placed out of direct sunlight and allowed to sit undisturbed for a <br /> minimum of 20 minutes, thereby allowing the air in the head space and soil to <br /> equilibrate <br /> An OVA or PID is calibrated and the batteries checked prior to each use. After the air <br /> in the sample jar has equilibrated, the probe of the OVA or PID is inserted into the <br /> jar through the aluminum foil The presence of any organic vapor measured will be <br /> recorded in parts per million <br /> Samples used for collecting organic vapor data are never submitted to a laboratory <br /> for analytical testing. <br /> Parker Environmental Services 4185 Rialto Court Pittsburg CA 94565-6116 <br /> Phone (510) 439-1024 Fax (510) 439-2566 <br />
