Why Alton wells carry these contaminants
Alton wraps the southeastern tip of Lake Winnipesaukee, with the resort village of Alton Bay at its center and Mount Major rising above the shoreline. About 5,900 people live here year round, more than nine in ten of them homeowners, spread across rural lots and lakefront property.
Most Alton homes draw from private wells in the granite and metamorphic bedrock of the Lakes Region. Statewide, about 46 percent of New Hampshire residents rely on private wells, and that bedrock is a natural source of arsenic along with uranium and radon.
USGS mapping shows elevated radon and uranium probability across much of this part of New Hampshire, and arsenic is tied to bedrock rather than to town lines. Because all three are invisible in water, a test is the only way to know an Alton well's levels.

Water treatment services available in Alton
These services are provided by the licensed local contractor you are matched with, sized to your Alton well and your home.
Arsenic Treatment
The highest-intent concern on New Hampshire bedrock wells. A licensed contractor sizes a system to your water and the arsenic species present.
Learn moreUranium Treatment
Naturally occurring uranium turns up in parts of New Hampshire bedrock. A contractor typically addresses it with anion exchange or reverse osmosis.
Learn moreRadon in Water Treatment
Waterborne radon is distinct from airborne radon. On bedrock wells a contractor reduces it with aeration or activated carbon.
Learn moreIron and Manganese Treatment
Iron and manganese cause staining, taste, odor, and buildup. Treatment is often bundled with an arsenic or uranium system.
Learn moreWhole-House Water Treatment
Point-of-entry systems treat the water entering the whole home. This is the route to weigh when more than one contaminant is present.
Learn moreReverse Osmosis Systems
Point-of-use drinking-water systems at the kitchen tap, often paired with a whole-house system for the rest of the home.
Learn moreCommon well water issues in the Alton area
Alton wells usually pair arsenic with uranium and radon from the bedrock, plus the iron and manganese that stain fixtures and laundry across New Hampshire. Where several contaminants show up, a contractor designs a whole-house system that treats them in the right order.
How to test and treat your Alton well
Testing is straightforward. You can send a sample to a New Hampshire accredited laboratory, order a test kit, or have the licensed local contractor we connect you with run a free in-home test. NHDES recommends a standard analysis every three to five years, with bacteria and nitrate tested yearly.
If you are buying or selling a Alton home, water comes up at the closing table. New Hampshire requires sellers of one-to-four-family homes to disclose details about the private water supply, including the date of the most recent water test, and a separate state notification reminds buyers that radon and arsenic can occur in New Hampshire well water and that testing is recommended.
The treatment path is the same three steps everywhere we work: request a free in-home test, the contractor tests your Alton water and reviews the results with you, and you receive a written, itemized quote with no obligation.

Do most Alton homes use well water?
Yes. Outside the village, most Alton homes draw from private bedrock wells, which are not tested by any agency. A test is the only way to know what is in a given well.
Are radon and uranium a concern in Alton?
USGS mapping shows elevated radon and uranium probability across much of this part of New Hampshire, and both come from the same bedrock as arsenic. A radiological test that includes radon and uranium is the way to know your levels.
How do I get an Alton well tested?
Use a New Hampshire accredited laboratory or request a free in-home test from the licensed local contractor we connect you with. NHDES recommends a standard analysis every three to five years.
