Abstract
Victoria, the capital of British Columbia, Canada, sits at the southeastern tip of Vancouver Island and developed early on as a major trading and industrial center in the Pacific Northwest. Today it remains a regional hub in an important location on the Salish Sea. Victoria largely followed broader regional environmental history patterns related to marine pollution. The city had a dense concentration of industry along its shoreline and discharged raw sewage directly into the harbor. Pollution from industry and sewage remained significant until environmental regulations were introduced in the 1970s and strengthened throughout the 1980s and 1990s. Since then, water quality in Victoria Harbor has improved significantly, though contaminated runoff and polluted sediments persist. In 2020, a wastewater treatment plant with primary and secondary treatment was completed, ending more than a century of raw sewage discharge. Despite this progress, the sediments and water of the harbor remain affected by pollution from historical activities and continued urban runoff. We propose remediation of harbor sediments, the implementation of tertiary wastewater treatment, expanded green infrastructure to reduce stormwater runoff, and the increased use of grey water to address Victoria’s marine pollution challenges. We acknowledge that such measures will be costly and require extensive coordination across government agencies and non-governmental organizations. However, they will improve the long-term health of Victoria Harbor and the Salish Sea.
