Kingwood Township radon testing and mitigation

Part of Kingwood Township, Kingwood Township is a large rural township along the Delaware between Frenchtown and Stockton, almost entirely farmland and woodland.

Housing stock. 18th and 19th century farmsteads and crossroads hamlets, with scattered later large-lot building.

Water supply. 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.

The ground under Kingwood Township

Kingwood sits over the Lockatong Formation across much of its area — the dark, thinly bedded lake-bed argillite of the Newark Basin, which carries uranium more readily than the red shale under the centre of the county and moves gas along its bedding and joint planes rather than through the rock. Soils over it tend to be thin. The housing is old and rural: stone farmhouses, mills and hamlet buildings on shallow foundations, frequently with cellars that were floored in part or not at all. That pairing of uranium-bearing bedrock and open stone cellars is why the western townships produce jobs that need membrane systems and serious sealing rather than a fan on a pipe.

None of that describes a particular property. Formations cross municipal boundaries freely, so where a specific address falls is a question for the NJ Geological Survey's bedrock mapping, and what it means under the floor is a question for a diagnostic test.

Around Kingwood Township. The requests come from the Baptistown crossroads; the Barbertown and Idell areas; the Route 12 and Route 29 corridors; the Lockatong Creek valley; the Delaware River frontage and the Byram area.

Working here

Open rural properties with ample room, though long drives and outbuildings can affect staging.

What moves the cost here

Room is plentiful, so access is not what costs money here — the foundation is. Membrane over an open cellar floor, sealing across rubble stone walls, and multiple suction points where a house has grown in stages are all common. Newer houses on the surrounding acreage install conventionally.

Kingwood lies over the uranium-bearing Lockatong Formation, which is a large part of why western Hunterdon returns readings people more often associate with the Highlands. The NJ Geological Survey's bedrock mapping is the place to confirm which formation sits under a particular address.

Much of its housing is pre-1900 farm and hamlet building on shallow stone foundations, so sub-membrane systems come up across the township far more often than sub-slab ones.

Permits and paperwork

Permits run through the Kingwood Township construction office. Wells here draw from the same fractured argillite as the soil gas, which makes the water-side reading a routine part of a complete picture.

Worth checking rather than assuming: mailing addresses here often cross municipal lines, and some towns share construction-code services, so the office that issues your permit may not be the one on your envelope.
