Emerging Chemical and Microbial Concerns in Water

This 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.

Due to the COVID-19 pandemic restrictions the course will be delivered online. There may be some changes to the way it has been traditionally delivered but the key learning objectives remain the same and will still be delivered with the full complement of CPD hours.

Issues addressed
