Water in North Stonington
Where North Stonington gets its water — and why it matters.
North Stonington has no townwide public water system. Homes here are on private wells, and many of them are drilled into bedrock rather than set in shallow gravel.
That distinction carries real weight in Connecticut. The state’s Department of Public Health specifically advises private well owners to test at least once — ideally every five years — for arsenic, uranium and radon, all of which occur naturally in groundwater in parts of the state. Those are not filtration talking points; they are state testing guidance, and they apply whether or not you ever buy a treatment system.
Alongside that, the everyday complaints here are the ordinary well complaints: iron, manganese, hardness and sulfur odour.

What homeowners notice
Common water concerns in North Stonington.
These are symptoms, not diagnoses. What is actually causing them at your address is a question for a test — but knowing what to look for is where it starts.
Manganese
Darker staining than iron — black specks, gray cast on white laundry.
Hardness
Scale on fixtures, soap that will not lather, water heaters that wear out early.
Sulfur odor
Rotten-egg smell, commonly stronger on the hot water side.
Two different starting points
City water and well water are different problems.
Private Well
If you’re on a private well in North Stonington
Everyone in North Stonington is a well owner, so everything starts with a test. Connecticut’s Department of Public Health suggests private well owners test every year for coliform bacteria, nitrate, nitrite, pH, odour, chloride, hardness, colour, sulfate, turbidity, iron and manganese — and test at least once, ideally every five years, for arsenic, uranium and radon, which occur naturally in groundwater in parts of the state. For a bedrock well in this part of Connecticut, that arsenic, uranium and radon test is worth doing on the state’s schedule regardless of whether you are thinking about treatment at all. If a result does come back that warrants treatment, the right equipment follows from the number — not from a catalogue.
Every recommendation we make is based on the water conditions in that specific home. We don’t quote equipment before we understand what the water is doing.

Questions
North Stonington water questions, answered.
Does North Stonington have town water?
No. Homes in North Stonington are on private wells.
What should I test my well for in North Stonington?
Connecticut's Department of Public Health recommends testing every year for coliform bacteria, nitrate, nitrite, pH, odour, chloride, hardness, colour, sulfate, turbidity, iron and manganese. It also recommends testing at least once — ideally every five years — for arsenic, uranium and radon, which occur naturally in groundwater in parts of Connecticut, and testing for lead at least once.
Why does my bedrock well matter?
Water drawn from rock tends to have a different chemistry from water drawn from shallow sand and gravel. It is one of the reasons Connecticut singles out arsenic, uranium and radon for testing. Knowing which kind of well you have helps your lab recommend the right panel.
Why does my well water stain fixtures orange?
Iron is the usual cause, frequently with manganese alongside it. Both are naturally occurring and both are aesthetic rather than health concerns — but they are persistent, and they are treatable once measured.
Can Harborline treat arsenic or uranium?
Treatment options exist for both, but we will not install anything for either on the basis of a conversation. Those require a laboratory result. Test first through a state-certified lab; if the results warrant treatment, we will talk about what actually addresses what you have.
Does Harborline serve Clarks Falls and Pendleton Hill?
Yes — the village, Clarks Falls, Laurel Glen, Pendleton Hill, Milltown and the rural roads between them.
