Author Description

The British Columbia Water Quality Branch is developing province-wide water quality criteria for use in assessing water quality data and preparing site-specific water quality objectives. These criteria are being developed substance by substance, beginning with those most urgently needed for water quality assessments and objectives. The tables comprising this report contain both working criteria awaiting approval and criteria approved by BC Environment. Substances covered by the criteria include particulates, nutrients, cyanide, nitrogen, metals, bacteria, chlorine, fluoride, ammonia in saltwater, and organic compounds such as chlorophenols and polychlorinated biphenyls.
