Well Water Filtration Systems in Southern NH

Common signs include orange staining (iron), black staining (manganese), rotten egg smell (hydrogen sulfide), cloudy water (sediment), or scale buildup (hardness). A water test gives you exact concentrations. We can help arrange testing before recommending a system.

The smell is caused by hydrogen sulfide gas, which is naturally occurring in some New Hampshire groundwater. It is not a health hazard at typical levels but is unpleasant. Aeration systems or oxidizing filters effectively remove it.

Yes. Iron treatment systems use oxidation and filtration to remove both dissolved and particulate iron. The right approach depends on your iron concentration and whether you also have manganese or sulfur issues.

Yes. Most well water treatment systems require periodic backwashing, media replacement, or salt addition depending on the system type. We will explain what your specific system needs.

Yes. New Hampshire has one of the highest rates of naturally occurring arsenic and radon in private well water in the country due to bedrock geology, with elevated levels common in granite-rich Southern NH towns. State guidance recommends every private well be tested. A.J. LeBlanc Heating can help arrange a state-approved water test and recommend treatment if arsenic or radon levels are elevated.

Arsenic is treated either at the point of use with a reverse osmosis system at the kitchen sink for drinking and cooking water, or whole-home with arsenic-specific adsorption media such as granular ferric oxide or iron-based filtration. The right approach depends on the arsenic concentration, whether it is arsenic III or arsenic V, and how the home uses water. We test, recommend, and install the appropriate system.
