...For decades, applying road salt has been regarded as a simple but vital tool in countering the dangers of slippery road conditions, but the downsides of its use are apparent with implications that extend beyond the cold months...

Philippe presented the plenary keynote presentation entitled “The Environmental Biogeochemistry of Phosphorus: A tale of too little or too much” at the 12th National Conference on Environmental Chemistry (NCEC) held on November 17-21, 2023, in Wuhan, China.

Philippe visited China University of Geosciences (CUG) in Wuhan China on November 13-17. The visit included in-depth discussions on collaborations between Waterloo’s Ecohydrology Research Group (ERG) and CUG’s Environmental Hydrogeology Group (EHG). 

Members of the Ecohydrology Research Group volunteered to facilitate kids’ science activities at the University of Waterloo’s Science Open House on Saturday, October 28th. Over 4,000 people attended the Science Open House and Gem and Mineral show this year!

The Second Joint Symposium of the International Societies for Environmental Biogeochemistry and Subsurface Microbiology was held in Banff on 22-28 October. Philippe Van Cappellen, Jovana Radosavljevic, and Erin Griffiths attended.

A new paper published in Journal of Geophysical Research: Biogeosciences presents the results of analyses of two sediment cores from Lake Wilcox, a kettle lake located in the greater Toronto area. The results give insight on the impacts of land use/land cover changes on lake P biogeochemistry, and into the impact of road salt-caused salinization on lake ecosystems. 


The second annual meeting of the Microplastics Fingerprinting project was held as a 2-day meeting from September 18th - 19th at the CIGI campus in uptown Waterloo. The aim of the workshop was to review the progress of the work completed over the last 2 years, and exchange ideas about further integration among the different work packages, while deepening collaborations with our external partners.

Philippe participated in a panel discussion entitled, "Protecting the Grand River: Microplastics and environmental stewardship in the Haldimand Tract," organized by Environmental Defence. Besides Philippe, the panel included Courtney Skye of the Six Nations of the Grand River, who is also the founder of Protect the Tract, and Karen Wirsig of Environmental Defence moderating the discussion.
