Why this comes up in Kingwood Township
Kingwood is well country with very little public supply. A well draws from the Lockatong argillite, which is precisely the formation that makes the soil-gas side of this township difficult. That is part of the context any crew working in Kingwood Township has to design around.
Kingwood Township — the state's own numbers
26% of the 524 test results NJDEP holds for Kingwood Township were at or above the 4.0 pCi/L action level — 136 of them. That puts it in Tier 1 — high potential.
18th and 19th century farmsteads and crossroads hamlets, with scattered later large-lot building.
Practicalities in Kingwood Township
Open rural properties with ample room, though long drives and outbuildings can affect staging.
Construction permits go through Kingwood Township, and installing radon mitigation for a fee anywhere in New Jersey requires NJDEP certification.
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.
The right answer depends on your specific building, which is why somebody has to measure it.
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.
