Concord, NH –The New Hampshire Department of Environmental Services (NHDES) today announced new and updated drinking water well test results for perfluorooctanoic acid (PFOA) in Litchfield, Manchester and Merrimack, New Hampshire, and that the private-well water testing area is being expanded from a 1-mile to a 1.5-mile radius from the Saint-Gobain facility in Merrimack. NHDES is expanding the testing radius in all directions based evaluation of test results to date. The expanded investigation area now includes portions of Bedford, Litchfield, Londonderry, Manchester and Merrimack.

Test Results: NHDES has received a total of 161 water well test results to date. Of the results received, 41 private wells (One in Manchester, seven in Merrimack and 33 in Litchfield) were found to contain PFOA concentrations at or above 100 parts per trillion (ppt), ranging from 100 ppt to 1,600 ppt; the well tested at 1,600 ppt is not used for drinking water purposes. An updated map and table of the test results have been posted on the NHDES PFOA investigation webpage under sampling data and map: http://des.nh.gov/organization/commissioner/pfoa.htm
