Stay in the know on all things drinking water

Dr. William B. Anderson is a Research Associate Professor and the Associate Director of the Water Science, Technology & Policy Group at the University of Waterloo. He has been active in drinking water quality and treatment research for more than 40 years, recently focusing on pathogen identification/removal/inactivation, assessment of adsorbed and desorption of contaminants on microplastics, better understanding of the role of colloidal nutrients on cyanobacterial growth in drinking water reservoirs, perfluorinated compounds, and biological filtration.

The past 15 years, Bill has maintained an email service drawing attention to items of interest to drinking water professionals including, for example, the latest research articles, regulatory updates, outbreak reports, topical issues, and media stories. Bill’s email service has expanded over time to include all interested individuals. These emails are now also archived here in a blog format as they are released, which can be explored by category or simply by scrolling through the posts below.
