Orchard Highlands - USEPA Arsenic Treatment Demonstration - Goffstown, New Hampshire
In 2004 AdEdge Technologies Inc. (AdEdge) was selected to implement six fullscale arsenic treatment demonstration projects as part of the USEPA Office of Research and Development arsenic research program (Round 2). These six sites were in addition to three USEPA Round 1 demonstration sites awarded to AdEdge in 2003. The purpose of the research effort is to provide information to fill-in gaps that exist for a number of technologies or compliance approaches and provide this information to utilities, engineering firms, regulatory officials, and others. One of the Round 2 sites, located in Goffstown, New Hampshire, is a small subdivision community that uses groundwater to meet its water-supply needs. The groundwater resource in Goffstown was determined to contain arsenic concentrations above the proposed maximum contaminant level (MCL) that will take effect in January 2006 (i.e., 10 parts per billion). Analytical data for the Orchard Highlands water system is summarized in the table to the right. AdEdge designed and installed a treatment system to safely and effectively remove arsenic from the drinking water source. The treatment system is described in the following paragraph.
