ORMGP’s 2025 annual report, Beneath the Surface, reflects on 25 years of work to document, interpret, and share groundwater data across south central Ontario.

The report highlights the scale of the program’s data, the partnerships that have shaped its growth, and the tools that help municipalities, conservation authorities, consultants, researchers, and other users make more informed water-related decisions.

It also looks ahead to ORMGP’s 25th anniversary celebration in 2026, including new ways the program is continuing to make groundwater knowledge more accessible and useful.
