Executive Summary:
The Raincoast Healthy Waters program launched in 2023 aims to monitor water pollution in select watersheds across British Columbia, focusing on fish habitat health. Community involvement is emphasized, with two sampling events each year — one in summer and one in winter. The recent winter sampling on January 16, 2024, involved collecting water samples from five categories: source water, river water, road runoff, tap water, and marine water.
Key Findings:
- The Anderson Creek watershed, covering 49 km², exhibited generally good water quality during the wet season, with no exceedances of Canadian Environmental Quality or Health Canada Drinking Water Guidelines.
- Road runoff showed the highest contamination levels, particularly in nutrients and per- and poly-fluoroalkyl substances. River samples had the highest coliform levels, while marine samples had elevated metals and pesticides.
- Source water was identified as the least contaminated.
The Healthy Waters program aspires to enhance community understanding and stewardship of local water quality, addressing contamination impacts from various sources over the next two years.
Overall, continued monitoring will aid in understanding the complex threats facing water quality in British Columbia, with insights leading to policy changes for the protection of salmon, whales, and human communities.
