Radon mitigation & testing in Amherst, NH

Bedrock wells and full radionuclide testing in Amherst

Many Amherst homes rely on private bedrock wells. NHDES says radon isn’t the only naturally radioactive substance common in New Hampshire well water — so a smart test covers more than radon.

What to test a bedrock well for

• Radon — test at least twice, about a month apart. (NHDES)
• Uranium and gross alpha — NHDES notes that wells high in radon are more likely to have elevated uranium or gross alpha, and labs often offer a package. (NHDES)
• Radium-226/228 if gross alpha is above 5 pCi/L, per NHDES’s step-by-step method. (NHDES)

Different problems, different fixes

Radon has to be treated whole-house because it escapes into the air. Uranium and other radionuclides can often be treated at the kitchen tap (point-of-use) since they aren’t volatile. (NHDES) A water-treatment specialist can explain options; a certified radon mitigator handles radon in air.

Don’t skip the air test

Air is still the bigger radon risk. Test the lowest lived-in level with a free state kit or a professional. (NH DHHS)
