Display Field: NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Wellhead Protection Areas are the areas of influence on the land around a municipal well, the size of which is determined by how quickly water travels underground to the well, measured in years. For the ORMCP, a standard 100 metre radius circle is provided around each municipal well, as well as a 0-2 year zone, 2-5 Year Zone, 5-10 Year Zone, and a 10-25 Year Zone.The shape of the WHPAs is based on numerical hydrogeological modelling results for all of the York Region production wells and are dynamic to some degree, since they can be influenced by a number of factors such as the slope of the land, the depth of the well, and the type of sediment. The maps that this data is based on have supporting reports that discuss their development and are available via the Water Resources group.
