Name: Vulnerability Scores

Display Field: SYSTEM

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The data shows the Vulnerability Scoring (VS) zones in accordance with the Technical Rules for the Clean Water Act (issued in December 2008) for all municipal well fields in York Region. VS values of 2-10 are provided within Wellhead Protection Areas (WHPA) A, B, C and D (which represent the 100 metre, 0-2 year, 2-5 year and 5-25 year zones respectively), as based on scoring rules provided by the Ministry of the Environment (MOE) in the Clean Water Act. The figures and the final report present results of data compilation and computer simulations of a complex geologic setting. As outlined in the final report, data errors and data gaps are likely present in information provided to the consultant (EarthFX Inc.). In addition, computer models represent a simplification of the actual geologic and hydrogeologic conditions, and are subjected to simplifying assumptions. The data has been created by EarthFX Inc. The geologic and hydrogeologic data used as input into the numerical modelling procedure has been provided by various sources, including the MOE water-well records, previous consulting/research reports, and York Region.Please refer to the Clean Water Act approved symbology when using this data.
