Waste Site Cleanup & Reuse in New England
New Hampshire 1,4-Dioxane Site
Beginning in October 2002, New Hampshire Department of Environmental Services (NH DES) became actively involved in sampling private residential drinking water wells in Atkinson, NH. Beginning in November 2011, NH DES sampled numerous residential drinking water wells in the area and detected 1,4-dioxane at various levels in over forty wells. Recent studies by EPA and NH DES have identified 1, 4-dioxane as a harmful contaminant associated with chlorinated solvent contamination. NH DES has been providing bottled drinking water to residents with 1,4 dioxane concentrations in drinking water wells exceeding the state standard of 3.0 parts per billion. In March 2012, NH DES requested EPA assistance to provide clean drinking water to the impacted Atkinson residents.
Contaminant of Concern
The contaminant of concern is 1,4-dioxane, which is an 'emerging contaminant.' This means that to date, under EPA's drinking water program, 1,4-dioxane is an unregulated contaminant that we are still learning about. However, there is still information which tells us that long term exposure to high levels may pose a risk to human health. That is why EPA and NH DES have been working to find a solution to this problem.
EPA's objective is to provide a clean and reliable water supply to residents impacted by 1,4 dioxane over the state standard of 3.0 parts per billion. EPA will extend a water line from Hampstead Area Water Company to the impacted neighborhood. The water line will be in two parts. The first will run down Island Pond Road and extend down the entire length of Brookside Terrace, Belknap Drive and Emery Drive. The second branch will run up Oak Ridge Drive to the intersection with Deer Run Road.
What to Expect
EPA and its contractors will begin work to put in the water line on Island Pond Road for the remainder of this construction season (as long as we can begin before the ground freezes). EPA will seal up the work through the winter, and begin again in the spring of 2014. In the coming months, EPA will work with homeowners with 1,4 dioxane concentrations in drinking water wells exceeding 3.0 parts per billion to gain access to their property and design hook ups from the home to the water line. These hook ups will not be completed until late spring of 2014.
