This document establishes water quality criteria for polychlorinated biphenyls (PCBs) in British Columbia. It synthesizes available scientific data to provide recommended limits for PCB concentrations in water bodies to protect aquatic life and human health.

This technical appendix serves as a foundational document for environmental regulation in British Columbia concerning PCBs. Its detailed scientific approach and data-driven recommendations are intended for use by environmental managers, policymakers, and researchers. The criteria presented aim to provide a clear, science-based standard for protecting water quality from PCB contamination.
