The Ontario Geological Survey, the Geological Survey of Canada, and Conservation Ontario hosted the 2023 Open House for the southern Ontario Groundwater Community on February 21 and 23. The open house objective was to update groundwater researchers, practitioners and water managers on the activities of the respective agencies and collaborators.

The following posters were presented on February 23 by our ERG members

Selenium (Se) is an essential micronutrient but becomes toxic when people are exposed to excess levels. A new paper published in the journal Environmental Science and Technology presents a detailed analysis of the Se distribution in the cold region mollisol agroecosystems of northeastern China. The results indicate that the Se can be sourced back to chemical weathering of oil shales from the watershed source area and deposited along with organic matter during the fluvial deposition.

Wanfa Wang, a former ERG International Visiting Graduate Student from Tianjin University, published a new paper in the Journal of Hydrology describing his PhD research on carbon cycling in dam reservoirs in karst regions. Co-authors from ERG include Steph Slowinski, Shuhuan Li and Philippe Van Cappellen. Chemical and physical carbonate rock weathering in karst regions supply large quantities of particulate and dissolved inorganic carbon (PIC and DIC) to rivers and, ultimately, to the ocean.

ERG group members gathered for our annual holiday party! Happy Holidays and Happy New Year!
