Executive Summary
Water is vital for life and requires protection and restoration in British Columbia’s fish habitats. In 2023, the Raincoast Healthy Waters program was initiated to monitor water pollution in selected BC watersheds, conducting biannual sampling in dry (summer) and wet (winter) seasons. This report details findings from the first dry season sampling on September 20, 2024, supported by the Pender Harbour Ocean Discovery Station (PODS).
Water samples were collected from five categories: source water, river water, road runoff, tap water, and marine water. Analysis identified 79 contaminants from 573 measured in Anderson Creek, revealing good water quality overall, though challenges from forest fires and runoff remain.
The watershed covers 49 km², flowing from Lyon Lake to Pender Harbour and historically inhabited by the shíshálh people.
Key Findings
- Most Contaminated Categories: Marine and tap water samples had high levels of E. coli, metals, PAHs, PPCPs, and other contaminants.
- Stream and River Samples: Highest concentrations of nitrates and pesticides detected.
- Contamination Trends: PFAS, pesticides, and PCBs were notably higher in dry season versus previous wet season data; however, PPCPs and nitrates were more concentrated in the wet season.
- Water Quality: Generally good; one aluminum concentration exceeded environmental guidelines, but no exceedances were found for Health Canada Drinking Water Quality Guidelines.
The program emphasizes community engagement in understanding water quality, leading to better stewardship of natural resources and potential policy changes to protect aquatic life.
