Sean Backus

Environmental Scientist, Section Chief\Great Lakes Watershed - Water Quality Monitoring and Surveillance

CURRENT S&T / RESEARCH - Contributing to Environment Canada’s mandate to ensure that water is clean, safe and secure; Assessing risks to Canadians and their environment posed by pollutants or other harmful or dangerous substances

  • Provide leadership and management of National Science Programs for environmental protection related to risk assessment and management
  • Provide innovative program integration for regional delivery of National Toxics Programs in support of Ecosystem Initiatives
  • Management of multi-disciplenary teams delivering targeted monitoring and research
  • National status (surveillance) and trends (monitoring) of chemicals of concern in aquatic ecosystems - spatial and temporal
  • Status and trends of priority threats in the aquatic environment
  • Research on emerging organic and inorganic contaminants in precipitation (e.g. flame retardants, nutrients)
  • Development of novel techniques for the determination of priority pollutants
