| Details: | SUMMARY: Questions about Marshland Plan Review for SW Source DETAILS: Fred Bolton to request information on approved cartridge filtration units planned for installation and treatment of the springs at Marshland. Since the well has violated the MCL for arsenic, the Association is re-developing their old surface water source and springs. I sent him a list of cartridges approved under LT2, but requested that he provide us with the make and model and a copy of 3rd party verification challenge study showing that the proposed system meets LT2 requirements and challenge study protocols. Fred said that he would provide that with the plan submittal. He said that the emergency work to replace the stream crossing waterline was completed with the new line cased and placed under the stream (originally, it was hung on a bridge that was washed out in the December 2007 storm). ACTION NEEDED: Submit plans for approval prior to the purchase of the cartridge filtration units in order to verify compliance with LT2. | ||
