Head, Wastewater Science Unit

Lead wastewater-related research and monitoring within ECCC, collaborate with federal, provincial, municipal, and academic colleagues on studies of trace contaminants in wastewater

Current research and/or projects

Reducing the impacts of contaminants on the natural environment:

  • lead for the wastewater monitoring program under the Chemicals Management Plan
  • Occurrence and fate of pharmaceuticals, personal care products, flame retardants, per- and polyfluorinated alkyl substances, antioxidants, metals, and other trace contaminants in municipal wastewater and solids treatment processes

Professional activities / interests

Coordinate a national monitoring program for chemical substances in wastewater influents, effluents and biosolids
