The concentrations of <br /> constituents are oeiow detectable limits in the \rater <br /> - sample collected on August 13, 1985 from MW-2. <br /> A limited pump test (6 hours) , utilizing the production <br /> well was conducted on October 1 , 1985 by a Kleinfelder <br /> hydrogeoingist and a 24 hour pump test was conducted <br /> between October 15 and 16. The pump test was conducted <br /> to assess what effect the production well may have.haa <br /> during it's previous use on the local shallow ground <br /> _. water gradient. During both Dump tests, the production <br /> well was run continuously at a flow rate of 4.25 gni <br /> Water levels in the four monitoring wells were recorded <br /> during the entire test. At no time was there any <br /> drawdown observed in any of the monitoring wells. The <br /> continuous pumping of the production well did not affect <br /> the local shallow ground water gradient beneath the tank <br /> excavation. J. H. Kleinfelder and Associates was not <br /> able to obtain any information on the history or the <br /> construction of the production well. The depth of the <br /> well and the depths of the perforations and pump are <br /> unknown at this time but is likely draining from a deeper <br /> zone. J. H. Kleinfelder could not measure the water <br />
