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.
If you would like to join Bill’s email list for updates straight to your inbox, you can send an email to Bill to be added to the list.

Drinking Water Quality Guidelines across Canadian: Jurisdictional Variation in the Context of Decentralized Water Governance
review identifies key differences in the regulatory approaches to drinking water quality across Canada’s 13 jurisdictions. Only 16 of the 94 CDWQG are consistently applied across all 13 jurisdictions; five jurisdictions use voluntary guidelines, whereas eight use mandatory standards.
A pilot study on the feasibility of testing residential tap water: Implications for environmental justice and health
The article offers a very different perspective, using citizen scientists and addressing implications for environmental justice and health.
researchers from Denmark are studying phytotoxins – those produced by plants – from the potential of them being contaminants with the potential to impair drinking water quality. Of several different phytotoxins spiked into groundwater and ultimately treated by 5 different filter types, two of them, jacobine N-oxide and senecionine N-oxide, were found to be non-biodegradable. They were also able to identify some degradation products.
The study examined 623,468 births and concluded that “TTHM exposure was associated with the increased risk of malformations of the nervous system, urinary system, genitals, and limbs in areas exclusively using chloramine. An association between chloramine-related chlorination by-products and congenital malformations has not previously been highlighted and needs further attention.”
It provides baseline concentrations and sizes for typical occurrence of natural and anthropogenic (manufactured) nanoparticles (NPs) including gold, cerium, titanium, and palladium (Au, Ce, Ti, and Pd) in US drinking water sources.
