radon-in-water aeration system in Hampton usually starts with a number somebody was not expecting.
What usually prompts the call
- A private well and an indoor reading that a soil-gas system did not fully explain
- A gross alpha or radon-in-water result from a Private Well Testing Act sample
- Readings that spike in the bathroom during and after a shower
Why this comes up in Hampton
The built-up borough has a public system; addresses beyond it generally do not. A well here draws from the carbonate rock of the Musconetcong valley.
Hampton Borough — the state's own numbers
43% of the 1,251 test results NJDEP holds for Hampton Borough were at or above the 4.0 pCi/L action level — 540 of them. That puts it in Tier 1 — high potential.
A compact railroad-era village of modest frame houses on small lots, with some later infill on the higher ground.
What access looks like here
Small level lots in the village with reasonable room at the sides of most houses.

How it's normally done
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.
Local experience matters here — the ground under Hampton does not behave like the other end of the county.
Who is allowed to do this in New Jersey
Under N.J.A.C. 7:28-27 this is not work a general contractor may take on. It requires a business certified by NJDEP for radon mitigation, with a certified mitigation specialist directing the work. We verify that on the state register, note the date, and route accordingly — but a verified certification is a fact, not a recommendation.
