What Hollis homes tend to deal with.

Southern NH

Hollis wells draw from the same granite bedrock that drives arsenic, uranium, and radon concerns throughout Hillsborough County. NHDES has repeatedly flagged southern Hillsborough as one of the higher-risk regions in the state for naturally occurring arsenic in private wells, and Hollis fits squarely inside that pattern. Uranium often appears alongside arsenic in deeper bedrock wells. Radon in water is common where radon in indoor air is already elevated. Hollis's agricultural history means nitrate testing is also worth including on private-well baselines, particularly for homes near current or former farmland. Iron, manganese, and hardness are routine findings. The Nashua River watershed runs through the edge of town, and proximity to Nashua and Merrimack also makes PFAS testing a reasonable add-on given the broader southern NH PFAS picture.

What we install here.

Hollis homes usually end up with a whole-home arsenic and uranium removal system, radon aeration where warranted, iron and manganese filtration, a softener, and a kitchen reverse osmosis unit. Where nitrates or PFAS come back elevated, treatment is matched to those findings. Free on-site testing drives every system design. NHDES PFAS rebate paperwork up to $5,000 is something we handle for qualifying homes.
