Managing the Impacts of Algal Blooms in Drinking Water Treatment Plants

October 16, 2019

This webinar is the second in a series; the first webinar (September 2019) examined the management of algal blooms using watershed-scale approaches.

Harmful and nuisance algal blooms are a recurring issue for municipalities across Canada, and their severity, frequency and distribution are increasing. Human activities such as urbanization and agriculture, as well as changes in climate like warmer water temperatures and more intense rainfall are contributing to algae proliferation. Due to the complex interaction of factors which determine whether algal blooms occur, and their severity and frequency, a holistic management approach is needed to minimize their impacts.

This two-part webinar series will look at potential solutions for the strategic management of algal bloom impacts on local water sources in a range of watershed landscapes. Join us to learn how some leading municipalities and academics in Canada are approaching this challenge. The first webinar (September 2019) will focus on reducing and minimizing algal blooms in drinking water sources using watershed management approaches. The subsequent webinar (October 2019) will focus on managing the impacts of algal blooms in drinking water treatment plants.

Who should attend this webinar series?

Utility managers, knowledge and solution providers, government regulators.
