Provincial Groundwater Monitoring Network (PGMN)
The Ontario Ministry of the Environment and Climate Change has been partnering with conservation authorities and their member municipalities on a provincial groundwater monitoring network (PGMN) since 2000.
The PGMN has been established to collect and maintain ambient (baseline) groundwater level and quality information from more than 450 wells, representing major aquifers across the province. Data from the monitoring network provides an early indicator for potential emerging issues such as climate change, water usage demand changes, and changes to water quality from both human-made and natural causes.
Ausable Bayfield Conservation Authority (ABCA) currently monitors water levels and quality at 16 locations across the ABCA watersheds.
Groundwater recharge area
(a) Natural processes, such as the infiltration of rainfall and snowmelt and the seepage of surface water from lakes, streams and wetlands;
(b) From human interventions, such as the use of storm water management systems, and;
(c) whose recharge rate exceeds a specified threshold.
A significant groundwater recharge area (SGRA) is one of four vulnerable areas identified in Ontario’s Clean Water Act, 2006.
