Approximately 38,475 <br />gallons of water were removed in August1999. <br />• Development water was analyzed for tracer dye that was used in the <br />drilling water during drilling. <br />Sampling <br />• August 30, 1999 water quality sample collected from newly completed B <br />Groove well using dedicated gas displacement pump. <br />• September 26, 1999 water quality sample collected using dedicated gas <br />displacement pump. Duplicate sample was also collected. <br />• October 27, 1999 water quality sample collected using dedicated gas <br />displacement pump. <br />Notes <br />Lost 2 3/16° BQ tremie line (from 215' - 475') in hole while cementing. Tremie <br />was cemented in place. <br /> <br />
