What Londonderry homes tend to deal with.

Southern NH

Londonderry sits on southern NH granite bedrock that drives arsenic, uranium, and radon concerns across Rockingham and Hillsborough counties. NHDES identifies this part of the state as a higher-risk zone for naturally occurring arsenic in private wells, and Londonderry fits the pattern. Uranium often appears alongside arsenic in deeper wells. Radon in water is common. Iron, manganese, and hardness are routine findings. Londonderry's agricultural history makes nitrate testing worthwhile for homes near current or former farmland. Proximity to Manchester and the broader southern NH corridor also makes PFAS baseline testing a reasonable add-on. Londonderry has municipal water service in parts of town, particularly along the Route 102 corridor, but much of the town remains well-dependent. Seasonal fluctuations in groundwater can also affect well yield and turbidity in shallower systems.

What we install here.

Londonderry well homes typically 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 PFAS or nitrates come back elevated, treatment is matched to those findings. NHDES PFAS rebate paperwork up to $5,000 is something we handle for qualifying homes.
