Radon-in-water aeration system in Frenchtown

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.

If you are looking into radon-in-water aeration system in Frenchtown, what the building sits on is the place to start.

What usually prompts the call

  • Readings that spike in the bathroom during and after a shower
  • Neighbours on the same aquifer with known radioactivity in their water
  • A private well and an indoor reading that a soil-gas system did not fully explain

Why this comes up in Frenchtown

The village core is on a borough supply; the slope behind it is less uniform. A well there draws from the rock at the western margin of the basin.

Frenchtown Borough — the state's own numbers

30% of the 658 test results NJDEP holds for Frenchtown Borough were at or above the 4.0 pCi/L action level — 195 of them. That puts it in Tier 1 — high potential.

Frenchtown is a riverside borough on the Delaware at the mouth of the Nishisakawick, opposite Uhlerstown in Pennsylvania, and that shapes what a system here has to be designed around.

Practicalities in Frenchtown

Small village lots close to the street; more room on the higher ground behind the centre.

Any permit for this runs through Frenchtown Borough. 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.

Typical cost in Hunterdon County, NJ

$3,800 – $6,500 — typical range, not a quote. What your building needs can only be settled by a certified business that measures it on site.

The right answer depends on your specific building, which is why somebody has to measure it.

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.
