Pollution Tracker is the first coast-wide, integrated marine pollution monitoring program in British Columbia. Sampling and analysis along the B.C. coast provides an overview of pollution and helps to guide best practices, management responses, and remediation. This coordinated initiative provides high quality, comparable, and accessible contaminant data in support of a healthy coastal environment.
