Whether radon-in-water aeration system is the right answer in Glen Gardner depends on what is actually under the floor.
How this normally comes up
- 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 Glen Gardner
Village addresses and slope addresses are often on different supplies. Where it is a well, the source is the Precambrian rock beneath the Spruce Run valley.
Glen Gardner Borough — the state's own numbers
39% of the 921 test results NJDEP holds for Glen Gardner Borough were at or above the 4.0 pCi/L action level — 359 of them. That puts it in Tier 1 — high potential.
Glen Gardner is a small borough in the Spruce Run valley between the Musconetcong Mountain ridge and the Highlands, and that shapes what a system here has to be designed around.
What access looks like here
Modest village lots on the flat, steeper and more constrained on the valley sides.
Construction permits go through Glen Gardner Borough, and installing radon mitigation for a fee anywhere in New Jersey requires NJDEP certification.
What a certified crew will do
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 sooner it is measured, the more of the options stay open.
The credential behind this work
New Jersey licenses this work specifically: a certified radon mitigation business, affiliated with at least one certified radon mitigation specialist. We check the NJDEP register before a crew receives anything from us and we log when we checked. Certifications lapse, so ask to see a current one before you sign anything.
System running and the reading hasn't moved?
One description is enough. We'll send it to certified local crews and leave the decision entirely with you.
