Radon-in-water aeration system in Sergeantsville

Point-of-entry aeration for private wells carrying radon into the house through the plumbing. The half of the problem an air system can't reach.

Whether radon-in-water aeration system is the right answer in Sergeantsville depends on what is actually under the floor.

What people describe first

  • A gross alpha or radon-in-water result from a Private Well Testing Act sample
  • A private well and an indoor reading that a soil-gas system did not fully explain
  • Neighbours on the same aquifer with known radioactivity in their water

Why this comes up in Sergeantsville

Public supply does not reach the village or the farmland around it. A well here draws from the Lockatong argillite — the uranium-bearing rock that makes this corner of the county what it is.

Delaware Township — the state's own numbers

42% of the 668 test results NJDEP holds for Delaware Township were at or above the 4.0 pCi/L action level — 283 of them. That puts it in Tier 1 — high potential.

Sergeantsville is the village at the centre of Delaware Township, near the state's last remaining covered bridge, and that shapes what a system here has to be designed around.

Getting the work done in Sergeantsville

Village lots are modest; the surrounding farm properties are open.

Any permit for this runs through Delaware Township. NJDEP radon certification has to be current before a business receives anything from us.

What the work involves

Aeration strips radon out of the water in a vented tank before it reaches the taps, then discharges it outdoors. It is the treatment the EPA points to for high waterborne radon, it needs a repressurisation pump and annual servicing, and it belongs at the point of entry — treating one bathroom does nothing for the rest of the house.

Certification, checked before referral

Installing radon mitigation for a fee in New Jersey requires NJDEP certification as a radon mitigation business, affiliated with a certified radon mitigation specialist (N.J.A.C. 7:28-27). We confirm that on the NJDEP register and record the date we checked. That is a check, not an endorsement — satisfy yourself before you hire.
