Sediment Standards Project
Current Focus: Phase 2 -- Foundational Research and Framework Development (2026-2027)
Developing a modern, robust scientific framework for updating BC's Contaminated Sites Regulation sediment standards.
Active workstreams: Matrix Sediment Standards Derivation Options, and implementation of the BN-RRM (Bayesian Network Relative Risk Model).
About the Sediment Standards Project
Project Overview
The Science Advisory Board for Contaminated Sites (SABCS) has partnered with the BC Ministry of Environment & Parks to collaboratively develop a scientific framework for modernizing the CSR standards.
The Science & Standards Technical Advisory Committee (SSTAC), working with the Technical Working Group (TWG), is leading the Sediment Standards Project, which integrates best-available science to protect aquatic ecosystems and the communities that depend on them.
