Microbial Source Tracking in Aquatic Ecosystems: The State of the Science and an Assessment of Needs

Fecal pollution of aquatic ecosystems is a significant problem in many areas across Canada and there is a growing need for a science-based approach to determine its sources. Identifying the correct fecal pollution source can help mediate conflicts between stakeholders in communities, and help target appropriate, cost-effective, corrective actions to prevent future pollution. Microbial source tracking (MST) is an emerging field that offers considerable promise for determining the source of fecal pollution.

An MST worksho p w as held in Toronto on March 7-8, 2005 , to review the state of MST science and its readiness for widespread application across Canada . This workshop report outlines: the state of the science; current MST activities in Canada , the U.S. and internationally; and an assessment of fecal pollution source tracking needs and policy “drivers” in Canada .
