Why this comes up in Raritan Township

The developed corridor and the rural township are not on the same footing. Where an address is on a well, it draws from the Passaic Formation shale — the same fractured rock feeding gas to the slab.

Raritan Township — the state's own numbers

35% of the 3,920 test results NJDEP holds for Raritan Township were at or above the 4.0 pCi/L action level — 1,383 of them. That puts it in Tier 1 — high potential.

Substantial suburban growth from the 1960s onward — ranches, splits and colonials with full basements — sitting alongside farmsteads and crossroads villages that long predate them.

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.

Two houses on the same road in Raritan Township can need completely different systems.

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.
