What Nashua homes tend to deal with.

Southern NH

Nashua's municipal water, delivered by Pennichuck, meets federal standards. The usual treatment footprint applies: chlorine residuals, disinfection byproducts, and occasional taste or odor variation. A large share of Nashua's housing stock predates 1986, which means interior lead plumbing is a real consideration at the tap even when the main water is clean. On the private-well side, homes in the outlying parts of the city and in surrounding communities sit on the same southern NH granite that produces arsenic, uranium, and radon issues across Hillsborough County. Nashua's proximity to Merrimack and the Saint-Gobain PFAS plume, plus its industrial history along the Nashua River, make baseline PFAS testing worthwhile on any private well. Iron, manganese, and hardness are routine. Nashua's denser development and roadway runoff also contribute to surface-water considerations for any shallow or surface-influenced wells.

What we install here.

For Nashua municipal customers, whole-home carbon filtration plus a kitchen reverse osmosis unit is the typical setup to handle chlorine, disinfection byproducts, and in-home lead risk. Well homes get a full panel including PFAS, arsenic, uranium, radon, iron, manganese, and hardness, with treatment built around the findings. NHDES PFAS rebate paperwork up to $5,000 is something we handle for qualifying homes.
