Pease Air Force Base has created extensive contamination in the Seacoast region, affecting drinking water supplies for thousands of residents and businesses. The contamination has reached both public water systems and private wells, making it one of New England's most significant contamination challenges.
Saint-Gobain's manufacturing facility in Merrimack has contributed additional contamination affecting surrounding communities and the Merrimack River watershed. Manchester's industrial history has created potential additional sources requiring investigation. New Hampshire's reliance on groundwater for most of its drinking water supplies makes contamination particularly concerning, as treatment options are limited for many small water systems.
