Short-term radon test in West Amwell Township

West Amwell Township owners ask about short-term radon test more than you would think for a town this size.

When this is the right question

• You finished a basement and want to know what you have been sitting in
• A previous test was done years ago and you have since changed the heating or the ventilation
• A buyer or a lender has asked for a radon test before closing

Why this comes up in West Amwell Township

Almost nowhere in West Amwell is inside a public supply area. A well draws from diabase on the ridge or Newark Basin sediment below it, depending which end of the township the property is on.

Farmsteads and older stone houses on the ridge roads, with substantial later single-family building on large lots.

Practicalities in West Amwell Township

Large rural lots with room to work; the wooded ridge properties can be harder to reach.

Construction permits go through West Amwell Township, and installing radon mitigation for a fee anywhere in New Jersey requires NJDEP certification.

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.
