y i <br /> Tests <br /> Monitoring wells have been drilled in several locations <br /> on the premises . Two monitor wells have been tested for the <br /> purpose of supplying make-up water and were found to be <br /> satisfactory, <br /> Monitor Well - 6 <br /> MW 6 is located near the retort pit (.east central) <br /> as shown bn the attached charts , It delivers <br /> about six gallons per minute of Chromium +6 <br /> solution , 700 to 1 , 400 ppm. The well is 75 feet <br /> deep and screened from 30 to 75 feet below surface <br /> in clay and sandy silt . It will operate for only <br /> forty minutes , twice a day . <br /> Monitor Well -- 213 <br /> MW 213 is located in the southwest quadrant of the . <br /> property , some 400 feet from the retort pit . It <br /> delivers about fifteen gallons per minute continuously <br /> of Chromium +6 solution , 90 to 140 ppm. MW 213 is <br /> 182 feet deep and screened from 120 to 180 feet <br /> below surface in silty sand , clay , and silt . It is <br /> anticipated that MW 213 would be operated eight . _ <br /> hours a day , three to five days per week, depending <br /> upon MCTC treating activity . <br /> Benefit <br /> The use of ground water from these wells will do two <br /> things : <br /> A. Provide MCTC with make-up water . <br /> B . Remove soluble Chromium from the ground water. <br /> By far the biggest benefit is to improve water quality . <br /> Conclusion <br /> It is requested that a permit be issued to allow-water <br /> to be pumped from the ground to provide make-up water for <br /> the wood treating operation . <br /> Yo s Truly , <br />.
