The GeologyOntario (includes OGSEarth) web pages will be updated with a new look in the coming weeks, starting at the end of September 2021.
The updated design improves the user experience by simplifying the layout, making the pages more mobile compatible, and aligning with other Ministry web pages.
Please contact Alphons Evers (alphons.evers@ontario.ca) if you encounter any issues after the change or have any questions.
During this update, this page will be removed. Please update your bookmark to the following: Southern Ontario Stream Sediment Geochemistry Survey.
The Southern Ontario Stream Sediment Geochemistry Survey consists of stream sediment data including inorganic (metals) chemistry concentrations determined in 2113 samples collected across southern Ontario.
Data includes: Geochemical metals data determined by ICP, loss-on-ignition (LOI) and particle size analysis (PSA) data including quality control results from Certified Reference Materials (CRMs) and analytical (pulp) duplicates.
