Provincial Groundwater Monitoring Information System

The Provincial Groundwater Monitoring Information System (PGMIS) is a web-driven application that assists the Ministry of the Environment and its partners to monitor the state of the Province's groundwater resources.

As part of Ontario's Provincial Groundwater Monitoring Network, PGMIS will enable the Ministry of the Environment and its partners in the Provincial Groundwater Monitoring Network to monitor groundwater conditions in the province. The information from the Provincial Groundwater Monitoring Network will provide an early warning system for changes in water levels caused by climatic conditions or human activities as well as changes in water quality from natural or anthropogenic (man-made) causes. The information will support informed decision-making on water-takings, drought management and land use planning.

Please read the Disclaimer before using PGMIS.
