NJ Known Contaminated Sites (KCSNJ)

Searchable database of active/pending/closed contaminated sites — updated daily.

RegWatch ingests this source on a daily cadence and surfaces relevant records on every matching property report. Records are normalized, cross-referenced with related sources, and presented in context rather than as raw dumps.

When you run a property report for an address in NJ, matching records from this source appear inline — with status, dates, dispositions, and links to the governing authority. Critical findings surface as in-app alerts when you save the property to your portfolio; email alerts are included with a Pro subscription.
