Water Filtration Services in Dover, New Hampshire

Dover is the anchor of the Seacoast region north of Portsmouth, sitting along the tidal Cocheco River. Most of the city is on municipal water, but outlying neighborhoods and nearby properties in Madbury and Rollinsford blend in with Dover's service area and often rely on private wells. The Seacoast water picture is distinct from the rest of the state, and we service Dover regularly.

What Dover homes tend to deal with.

Seacoast

Dover's proximity to the former Pease Air Force Base and the Pease Tradeport puts it in the broader Seacoast PFAS awareness zone. Pease is a documented PFAS contamination site tied to decades of AFFF firefighting foam use, and while the Haven well was shut down years ago, regional concern about PFAS in Seacoast groundwater remains high. Private wells in Dover and surrounding Strafford County towns should be tested for PFAS as part of any baseline workup. Beyond PFAS, the Seacoast area has its own water quirks: salt intrusion in wells close to tidal water, iron and manganese from coastal plain sediments, and harder-than-expected water in bedrock wells further inland. Municipal customers deal with chlorine and the usual disinfection byproducts. Older parts of Dover have pre-1986 housing stock where lead in interior plumbing is a real consideration at the tap even when the main is clean.

What we install here.

For Seacoast homes, PFAS testing is a standard part of the first visit. Depending on the panel, the right system may be a dedicated PFAS-rated point-of-entry or point-of-use unit, often combined with reverse osmosis at the kitchen sink. Iron, manganese, and softening address the more routine issues. We manage the NHDES PFAS rebate paperwork up to $5,000 for qualifying homes. Free on-site testing is the first step.
