Mettawee Community School - Arsenic Treatment - West Pawlet, Vermont
In the summer of 2004, AdEdge Technologies, Inc. was selected by the Mettawee Community School to supply and install an arsenic treatment system for treating water serving the school and facilities. The elementary school site is located on the west side of the state near the New York border. This was the first system utilizing Granular Ferric Oxide (GFO) adsorption technology in the state for a Non-Transient, Non-community (NTNC) public water system. For this project, AdEdge coordinated closely with the Vermont Water Supply Division (WSD) and the school’s engineer, Enman Engineering to design and permit the system. AdEdge utilized Water Works, a local water treatment company to assist with installation. For a two-year period prior to installing the new arsenic treatment system, the facility elected not to utilize the water supply due to the arsenic content which is approximately 26 parts per billion (ppb). Before the new treatment system was placed on-line in November, 2004, the school was having bottled water supplied each month to serve the potable water needs. The table shown depicts the water assay for the site. Some of the more important water quality parameters are shown.
