Sealing and Decommissioning Unused Wells

An unused well is an open path from the surface straight into the aquifer that supplies the surrounding properties. New Jersey regulates how wells are sealed, and capping one or filling it with dirt does not meet that standard.

When a well needs to be sealed

A replacement well was drilled

The old well stays a contamination path until it is properly sealed, even if nothing is connected to it.

Property development or subdivision

Often required before construction or before a lot can be approved.

The well is contaminated or collapsed

Sealing prevents the problem from reaching the aquifer other wells draw from.

How it is done

Obstructions are removed, then the borehole is grouted from the bottom up so no void is left behind.
