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.
School and childcare center drinking water: Copper chemistry, health effects, occurrence, and remediation
US schools and childcare centers including that “flushing contaminated water was the most evaluated remedial action but was unreliable because copper quickly rebounded when flushing stopped.” They point to a second potentially important finding, “building water treatment systems have been used, but some were not capable of making the water safe.
We find consistent and robust evidence that drilling shale gas wells negatively impacts both drinking water quality and infant health. These results indicate large social costs of water pollution and provide impetus for re-visiting the regulation of public drinking water.
Drivers of Disinfection Byproduct Cytotoxicity in U.S. Drinking Water-Should other DBPs be Considered for Regulation
We report the most comprehensive investigation of drinking water toxicity to date, with measurements of extracted whole-water mammalian cell chronic cytotoxicity, over 70 regulated and priority unregulated DBPs, and total organic chlorine, bromine, and iodine, revealing a more complete picture of toxicity drivers.
a global-scale study of active pharmaceutical ingredients (API) pollution in 258 of the world’s rivers, representing the environmental influence of 471.4 million people across 137 geographic regions.
As implied by the name it is the 5th in a series of monitoring rules that provides data for regulatory considerations. An important highlight is the inclusion of 29 different per-and polyfluoroalkyl substances (table below).
Following a request for comments in July 2020 they have released Guidance on Monitoring the Biological Stability of Drinking Water in Distribution Systems. The intent of the document “is to provide responsible authorities, such as municipalities and water system operators, with an overview of: 1) causes of microbial water quality deterioration in the distribution system; 2) monitoring tools that can be used to assess biological stability; and 3) distribution system management strategies.
