2026-04-17

The B.C. copper water quality guideline (WQG) for the protection of aquatic life was updated in 2019 and now uses a biotic ligand model (BLM) to account for site specific toxicity modifying factors such as pH, dissolved organic carbon (DOC) and hardness. The B.C. copper BLM software, available on the B.C. WQG website can be used to calculate the copper WQG if site specific concentrations of the toxicity modifying factors are known. This dataset provides acute WQGs for various concentrations of pH, DOC and hardness that can be used to look-up WQGs without needing to run the BLM software.
