Application of RBCA in Municipal Wellfields and Watersheds

This document provides guidance on the application of Risk-Based Corrective Action (RBCA) in municipal wellfields or watersheds in New Brunswick. As with all contaminated sites in New Brunswick, the management approach to be used in municipal wellfields and watersheds incorporates the principles of RBCA.

The RBCA process is used as a reactive approach to protect groundwater and surface water and human health once contamination is found in the environment. The RBCA process ensures that what residual contamination may remain does not pose an unacceptable risk to human health and the environment. In municipal wellfields and watersheds, emphasis is placed upon ensuring that there are no unacceptable health or aesthetic impacts to drinking water.
