Emerging Chemical and Microbial Concerns in Water

This 12hr course has been designed in response to IWES feedback indicating a strong interest in emerging water quality issues. Participants will be introduced to a range of high-profile emerging contaminants that have presented unique difficulties and concerns for drinking water and wastewater management.

This will include an introduction to the principles of assessing chemical and pathogen risks, which will then be applied to a range of emerging contaminant risk contexts including: novel sanitation systems and reuse, opportunistic pathogens and engineered systems, and climate change.

The material is aimed at raising awareness regarding key issues particular to some of these emerging contaminants. These include potential environmental and public health risks, factors likely to lead to elevated concentrations and treatment process effectiveness.

Issues addressed


  • PFOS, PFOA and other perfluorinated compounds
  • Chlorinated and brominated flame retardants
  • Hormones and other endocrine disrupting chemicals
  • Pharmaceuticals and personal care products
  • Nanoparticles
  • Cyanotoxins
  • NDMA and other nitrosamines
  • Iodinated and brominated disinfection byproducts
  • Microplastics.


  • Introduction to pathogens in water
  • Assessment and management of microbial risk
  • Emerging behaviours: novel urban water systems and new exposures (incl. norovirus and Cryptosporidium)
  • Emerging environments: changes to the built environment and climate change (incl. Legionella spp. and Naegleria fowleri)
  • Emerging contaminants: how to assess and manage the risk of a new pathogen in water (incl. SARS-CoV-2)

What do you get

  • Access to two leading experts
  • Course book and digital course notes.
  • 12 CPD hours

Who should attend

Anyone with an interest in updating their knowledge of chemical and microbial water quality contaminants. This includes those responsible for environmental assessment, drinking water and wastewater treatment, laboratory analysis and stakeholder communications.
