Physical Scientist, Research

Conduct wastewater-related research and monitoring within ECCC and 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:

  • Evaluating the 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.
  • Communicating wastewater-related contaminants information.

Professional activities / interests
