Southern N.H. PFOA Investigation Update
Updated Drinking Water Well Test Results and NHDES Expanding Area for Private Well Testing

Concord, NH - The New Hampshire Department of Environmental Services (DES) 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 on 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.

Investigation test results to date for the Merrimack Village District Water Works are in the following table:

Well Name 3/9/2016
(nanograms/Liter)
(parts-per-trillion)
3/31/2016
(nanograms/Liter)
(parts-per-trillion)
MVD-2 17 27
MVD-3 Not sampled because well was shut down for scheduled maintenance Not sampled because well was shut down for scheduled maintenance
MVD-4 (off-line) 90 90
MVD-5 54 (52 duplicate) 56
MVD-7 Not sampled because well was shut down for scheduled maintenance 26
MVD-8 Not sampled because well was shut down for scheduled maintenance 8.5 (9.7 duplicate)

 

NHDES will be resampling the MVD wells on a weekly basis during the investigation.  

All residents of Litchfield living within the current 1-mile investigation radius, as well as those on the following streets outside of the radius, qualify to receive bottled water: Courtland Avenue, Lance Avenue, Jeff Lane, Mike Lane, Ronisa Avenue, Ivy Way, Robyn Avenue, Acorn Way, Oak Drive, Sybil Lane, Garden Drive and 377-450 Charles Bancroft Hwy (north of Midway Ave. and south of Strawberry Lane). Residents of Litchfield, Manchester and Merrimack whose wells to date have tested above 100 ppt of PFOA are already receiving bottled water. Saint-Gobain has communicated to NHDES that they will pay for the bottled water being provided.

NHDES expects to be provided soon with results from soil and groundwater test results taken at the Saint-Gobain facility.

A map of the 1.5 mile radius is available on the NHDES PFOA investigation webpage under sampling data and maps. Residents within the 1.5 mile radius who would like to request a well test can submit the following form to NHDES: https://www.surveymonkey.com/r/NHDES-S-03-008 .
