Sub-slab systems for chlorinated solvent and petroleum vapours. Same hardware as radon, an entirely different regulatory route.
This comes up often enough here that most certified crews in the county have a settled way of handling it.
What usually prompts the call
- A site with a known contaminated-groundwater plume nearby
- A vapour-intrusion investigation carried out under an LSRP
- Solvent odours in a lower level rather than a radon result
- A property in a state remediation programme
What a certified crew will do
Soil vapour intrusion from chlorinated solvents and petroleum uses the same entry routes as radon and often the same style of sub-slab system, but the investigation, the design approvals and the long-term monitoring run through New Jersey's site remediation framework and a Licensed Site Remediation Professional. It is a different regulatory job wearing similar hardware.
Typical cost in Hunterdon County, NJ
$5,000 – $30,000 — typical range, not a quote. What your building needs can only be settled by a certified business that measures it on site.
We publish this but don't route it
Soil vapour intrusion from solvents and petroleum runs through New Jersey's site remediation framework and a Licensed Site Remediation Professional, and we have no verification path for that. If it sits alongside a radon question, tell us about the radon side and we will route that part.

Towns where this is the right question
These are the towns whose geology and housing stock actually put this on the table.
Newark Basin shale country
Red shale and mudstone of the Passaic Formation under Flemington and the centre of the county. Fractured rock, plenty of basements, and a mix of public water and wells.
Diabase uplands and the Delaware corridor
Sourland-type diabase and the dark argillite of the Lockatong Formation. Stone farmhouses, open crawl spaces, and river-town cellars cut into rock.
