The cuttings produced during well construction will be placed on <br /> the paved parking area of the station and covered with visquine <br /> plastic (above and below) to prevent runoff and/or leaching to <br /> the uncontaminated soil . Disposal to the appropriate landfill or <br /> other methods of soil disposition will be determined at a later <br /> date. <br /> WELL DEVELOPMENT <br /> The new monitoring well will be developed by manually surging the <br /> well over the entire length of the below water slots with a <br /> plunger Ground water will then be pumped from the well until it <br /> flows clear. The waste water produced by this process will be <br /> placed in labeled 55 gallon drums, which will be later sampled. <br /> The results of this sampling will determine the method of <br /> disposal. <br /> GROUND WATER SAMPLES <br /> After the new monitor well is developed, WEGE personnel will <br /> collect ground water samples and have them analyzed at a state <br /> certified laboratory for Total Petroleum Fuel Hydrocarbons as <br /> gasoline with BTEX Distinction, utilizing EPA Methods M801.5 and <br /> 602 The purged ground water produced from the sampling rounds <br /> will be placed and labeled in DOT approved 55 gallon drums on <br /> site The results of samples taken from this stored purged water <br /> will determine disposal method <br /> Before the ground water sampling a state certified land surveyor <br /> will survey in the elevation of MW8 . The well surveying will be <br /> done to . 01 feet with reference to mean sea level as the <br /> benchmark and taken to the top of casing for the well . <br /> Methods and Procedures <br /> Prior to sampling each well, WEGE personnel will obtain two <br /> measurements. The depth to ground water and the product <br /> thickness using a depth to water-product interface probe. If no <br /> product is present in a given well, a ground water sample is <br /> collected using a fresh bailer <br /> Before collecting the ground water sample, WEGE personnel purge <br /> the well. This is accomplished by removing ground water from the <br /> well until the water quality parameters (temperature,., pH, and <br /> conductivity) stabilize. Water produced by the purging process, <br /> is collected in a 55 gallon drum. <br /> 8 <br />
