MW <br /> #1 and#2 were sampled on July 25 and MW#3 and#4 were sampled on August 1. Due to the <br /> disjointedness of MW#3, the pump became lodged in the well. On August 1, a pry bar was used <br /> to dislodge the pump and MW#3 and #4 were sampled. <br /> These wells surround an underground storage tank in the SEC of the subject property. Each of <br /> the four wells had approximately five casing volumes of water extracted prior to the actual sample <br /> taken. <br /> For MW #1 and MW#2, a bailer was used to sample these two wells. After sampling, the bailer <br /> was washed inside and out with a Trisodium Phosphate (TSP) solution and triple rinsed with DI <br /> water. The bailer rope was also washed after each MW sampling. A purge pump was used to <br /> sample MW# 3 and MW#4. After sampling, the pump was cleaned and purged with the TSP <br /> solution. <br /> Two - one liter samples were drawn from each MW and placed in an ice chest at approximately <br /> 4p C. The requested testing is for TPH and EPA 625. Four glass sample bottles for MW#1 and <br /> #2 were delivered to JL Labs on Thursday afternoon at 4:00 P.M., July 25, 1996. Four glass <br /> sample bottles for MW#3 and #4 were delivered to JL Labs on Thursday afternoon, August 1, <br /> 1996, at 4:07 P.M.. <br /> We appreciate the opportunity to provide this service for you.
