[SRRA]: Impact to Ground Water - Capping

The Department would like to announce the availability of the following technical guidance document:

"Capping of Inorganic and Semivolatile Contaminants for the Impact to Ground Water Pathway"

Capping was previously not permitted for the Impact to Ground Water Pathway. This policy has been revised such that capping is now permitted for semivolatile and inorganic contaminants providing certain site-specific conditions have been met. This guidance document lists these conditions and notes that, at a minimum, a capped site will require a deed notice and engineering controls and an approved Remedial Action Permit for Soils for the long-term maintenance of the deed notice and engineering control.

This document was developed by Department staff and external stakeholders, and is available for viewing and downloading on the SRP Remediation Standard web page at
