Tom Edge

Research Scientist - Study Leader, Waterborne pathogens

CURRENT S&T / RESEARCH - Contribute to clean water supplies by understanding waterborne pathogen threats to source waters used for drinking, recreation, and food production

  • Microbial source tracking of pathogen pollution
  • Occurrence of waterborne pathogens in aquatic ecosystems
  • Microbiology of beaches and use of E. coli as a water quality indicator
  • Application of genomics tools (e.g DNA microarrays, PCR) in environmental microbiology
  • Biotechnology and environmental risk assessment of genetically modified organisms


Co-leading a national study to develop a Canadian water quality standard for waterborne pathogens in agricultural watersheds under the National Agri-Environmental Standards Initiative (NAESI)

Serving as scientific advisor on Health Canada committee revising the Guidelines for Canadian Recreational Water Quality

Served as member of Canadian United Nations delegations negotiating the Biosafety Protocol for genetically modified organisms under the UN Biodiversity Convention
