These wells surround an underground <br /> storage tank in the SEC of the subject property. Each of the four wells had approximately five <br /> casing volumes of water extracted prior to the actual sample taken. <br /> MW#I had rainwater in the Christy Box up to the top of the 2 inch casing. If there was <br /> rainwater intrusion into the well, it was not a significant amount. <br /> After each sample event, the bailer was washed inside and out with a Trisodium Phosphate (TSP) <br /> solution and triple rinsed with DI water. The bailer rope was also washed after each MW <br /> sampling. Two - one liter samples were drawn from each MW and placed in an ice chest at <br /> approximately 4* C. The requested testing is for TPH and EPA 625. The eight glass sample <br /> bottles were delivered to JL Labs under COC on Friday morning, April 21, 1995, after overnight <br /> refrigeration. <br /> We appreciate the opportunity to provide this service for you.
