FIELD PROCEDURES <br /> Groundwater Measuring, Purging, and Sampling <br /> The water level in each well was measured with an electronic water level indicator The wells <br /> were checked for free product with a clean, Teflont bailer prior to purging and sampling When <br /> free product was not observed, groundwater from monitoring wells MW1 through MW8 was <br /> purged with a 2-inch diameter submersible pump Purging of the wells included the removal of <br /> approximately three well volumes of water from each well Groundwater samples were then <br /> collected with new polyethylene disposable bailers and decanted into appropriate sampling <br /> containers provided by the analytical laboratory The samples were immediately placed in an ice <br /> chest containing ice Samples were transported under chain-of-custody documentation to a <br /> California Department of Health Services-certified laboratory for analysis of Total Petroleum <br /> Hydrocarbons as gasoline (TPH-g) using modified EPA method 8015, Benzene, Toluene, <br /> Ethylbenzene, and Total Xylenes (BTEX) and Methyl Tertiary Butyl Ether (MTBE) using EPA <br /> method 602 <br /> The purging equipment was cleaned with a solution of liquinox detergent and water between each <br /> well to minimize the potential for cross-contamination All water removed during purging <br /> operations was placed in sealed, labeled 55-gallon drums and stored on-site <br /> INK <br /> WALLACE KUNL <br /> Reyt�a t�r� 6 ASSOCLATES INC <br />
