“Aquarion Water Company recently announced the completion of a water treatment system upgrade at the company’s Mill Road Treatment Plant in North Hampton. 

The upgrade project was undertaken to address per- and polyfluoroalkyl substances (PFAS) present in the water. As a result of the system upgrade, PFAS levels, which were already in compliance with state regulations, will be even lower.

PFAS are a group of man-made chemicals used in a wide range of products and commercial applications. PFAS can enter drinking water supplies in a number of ways including through industrial and commercial releases to water or air, discharges from sewage treatment plants, leaching from septic systems and landfills, land application of contaminated sludge, and the use of fire-fighting foam.

Aquarion is vigilant about testing for and monitoring PFAS levels and all water delivered to residents and businesses meets regulatory standards. 

The company had to reduce water production from one North Hampton facility, Well 6, to meet required PFAS limits. In order to restore full water capacity, Aquarion installed a PFAS removal system at Well 6. The system, which is sited at one of the company’s existing buildings, uses Granular Activated Carbon filtration to remove PFAS. The water, once treated, is blended with water from other wells in the area and delivered to customers.”…
