5.1.2 Provincial Data Sources

  • WTP_WS_Water Filtration Plant (MMA): This geodatabase, which was provided to the Neptis Foundation by the Ministry of Municipal Affairs, contains information from 2005-2006. It links Drinking Water System information to mapping coordinates, population served, and average/maximum daily flows.
  • Drinking Water Information System (MOECC): This MOECC database maintained by the Drinking Water Programs Branch profiles drinking water systems across Ontario. The profile information can be linked to other databases, but does not track flow data.
  • Permit To Take Water (MOECC): This publicly available database of permitted water takings is available for download from the MOECC website. Other groups involved in efforts such as the Oak Ridges Moraine Groundwater Program and Source Water Protection Plans have pointed out limitations in this database, but have used and updated them for their own work.
  • Water Takings and Reporting System (MOECC): This web-based reporting system is used by permitted water users to report actual water takings to the MOECC. The data are under review for release under the province's open data catalogue.
  • Water Well Information System (MOECC): This publicly available database with limited information has been used by the Oak Ridges Moraine Groundwater Program and Source Water Protection Plan consultants for modelling and other projects.
  • Provincial Water Quality Monitoring Network (MOECC and conservation authorities): This publicly available database contains reports on groundwater quality and quantity. There is also a Provincial (Stream) Water Monitoring Network that collects information on surface water quality.
  • Water Quantity Geodatabase (Ministry of Natural Resources and Forestry): This publicly accessible database is designed to coordinate the maintenance and collection of Water Budget and Water Quantity Risk Assessment information completed for Tiers 1 and 2 under the Clean Water Act. Tier 1 and Tier 2 assessments (done at the subwatershed level) are less detailed than a Tier 3 risk assessment, which "focuses on the local area around the municipal wells and assesses the risk of the municipal supplies not having a sufficient quantity of water available to provide the existing and future populations."[1] The geodatabase allows users to store, query, and view the water budget results produced for the Technical Assessment Reports for Source Protection Areas. Once complete, the database may provide new insights into water quantity management within each jurisdiction.
  • Source Protection Information Atlas (MOECC): The atlas provides a provincial picture of vulnerable areas, including 970 municipal Well Head Protection Areas (WHPA), 150 municipal drinking water Intake Protection Zones (IPZ), Highly Vulnerable Aquifers (HVA), Significant Groundwater Recharge Areas (SGRA), and related features.
