Why this comes up in Sergeantsville

Here is what makes Sergeantsville particular: 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

The usual approach

A short-term test means a sealed-house condition for at least 48 hours with a continuous monitor or a pair of charcoal detectors placed at the lowest lived-in level. The house has to stay closed the whole time, which is the part that most often invalidates a result. In New Jersey the placement and the reading both have to be done by a certified measurement business for the result to count in a real-estate transaction.

Typical cost in Hunterdon County, NJ

$150 – $325 — typical range, not a quote. What your building needs can only be settled by a certified business that measures it on site.

A crew that works Delaware Township regularly will have met this pattern before.

New Jersey requires certification for this

Measurement is certified separately from mitigation. Under N.J.A.C. 7:28-27, testing for radon for a fee in New Jersey requires NJDEP certification as a radon measurement business. A crew certified to install systems is not thereby certified to place and read the detectors. We only route this work to businesses we have checked on the measurement side.
