Common Water Issues in New Hampshire
Hard Water
Hard water means your water contains a lot of dissolved minerals, mainly calcium and magnesium. In a New Hampshire home, that often shows up as white scale on fixtures, spots on dishes, soap that will not lather well, stiff laundry, and buildup inside water heaters and plumbing. It is usually more of a home-comfort and appliance-life problem than a serious health issue, but it can still be frustrating and expensive over time.
Typical solutions available: Water softening systems can reduce the mineral buildup and help protect plumbing and appliances.
Iron and Manganese
Iron and manganese are very common in New Hampshire well water. They often cause orange, brown, or black staining in sinks, tubs, toilets, and laundry, and they can also make water taste metallic or look discolored. Even when the water is clear, these minerals can still be present and create ongoing staining and buildup problems around the home.
Typical solutions available: Whole-home filters are available to remove staining minerals before they reach your faucets, showers, and appliances.
Arsenic
Arsenic is one of the best-known private well concerns in New Hampshire, especially in parts of the state with bedrock wells. The problem is that arsenic has no obvious taste, smell, or color, so many homeowners would never know it is there without testing. Because it is a health-related contaminant, it is one of the most important things to check for in well water.
Typical solutions available: Special arsenic filtration systems or drinking-water systems can remove it once testing confirms the problem.
PFAS
PFAS, sometimes called “forever chemicals,” have become a major water concern in parts of New Hampshire. These compounds do not cause obvious staining or taste problems, so they are easy to miss without lab testing. In homes with private wells, PFAS testing can help determine whether extra treatment is needed to make drinking water safer.
Typical solutions available: Activated carbon or reverse osmosis systems are commonly used to reduce PFAS in drinking water.
Bacteria
Bacteria in well water is often linked to surface water getting into the well, flooding, well construction issues, or nearby septic influences. Unlike some mineral problems, bacteria can be an immediate health concern. Since contamination is not always visible, annual testing is especially important for private well owners in New Hampshire.
Typical solutions available: Homeowners may need well repairs, disinfection, or a UV treatment system depending on the cause.
Nitrate
Nitrate can enter water from septic systems, fertilizer, and other sources tied to land use. It is one of the contaminants New Hampshire recommends testing for regularly, especially in private wells. Like arsenic and PFAS, nitrate usually is not something you can see, smell, or taste, which is why testing matters so much.
Typical solutions available: Drinking-water treatment systems such as reverse osmosis can reduce nitrate when testing shows elevated levels.
Radon and Uranium
Some New Hampshire homes, especially in certain geologic areas, may have groundwater with elevated radon or uranium. These are naturally occurring contaminants tied to local rock and soil conditions, not something caused by dirty-looking water. Because both are invisible in the water itself, homeowners usually only find out through proper testing.
Typical solutions available: Specialized treatment systems are available, including systems that remove gases or target radioactive minerals in water.
MTBE and Other VOCs
MTBE and other volatile organic compounds are usually tied to gasoline, fuel storage, spills, or industrial contamination rather than natural geology. These issues are not present in every area, but they are important in some parts of New Hampshire and can affect water taste, odor, and safety. If a home is near older fuel infrastructure or a known contamination area, testing is a smart precaution.
Typical solutions available: Carbon-based filtration systems can often reduce these fuel-related or chemical contaminants.
Final Note
The biggest thing New Hampshire homeowners should know is this: clear water is not always clean water. Many of the state’s most common water problems cannot be seen, smelled, or tasted, which is why testing is the first step before choosing any treatment system.
