WHPA Vulnerability Analysis for the Region of Peel Wellfields, Ontario
Earthfx was hired by the Region of Peel to develop wellhead protection areas and contaminant vulnerability assessments for the Caledon East and Palgrave communities. Project work began with the extension and refinement of a model originally developed for the Oak Ridges Moraine. The model layers were expanded to include the main units of the Niagara Escarpment
Vulnerability Assessment and Scoring of Wellhead Protection Areas, Regional Municipality of York, Ontario
An analysis of intrinsic vulnerability to contamination at 37 active municipal groundwater supply wells operated by the Regional Municipality of York was completed as part of a Source Water Protection initiative. The Schomberg, Aurora, Newmarket, Ansnorveldt, Holland Landing, Queensville, Ballantrae, and Mt. Albert wellfields are located north of the regional groundwater divide that runs parallel to the east-west axis of the Oak Ridges Moraine (ORM). The Nobleton, Kleinburg, King City, and Stouffville wellfields are located south of the regional groundwater divide. Most of the wells are screened in the deeper, confined aquifers (i.e., the Thorncliffe Aquifer Complex or Scarborough Aquifer Complex).
Updated Wellfield Vulnerability Analysis for the Keene Heights Wells
Earthfx Incorporated delineated wellhead protection areas (WHPA) for all municipal wells within the Trent Conservation Coalition Drinking Water Source Protection Region. Included in this analysis were the municipal wellfields serving the communities of Millbrook, Crystal Springs and Elgeti, and Keene Heights located north of Rice Lake.
Wellhead Protection Area Delineation and Vulnerability Scoring for the Brantford Airport Wellfield
The Brantford Airport wellfield, located 6 kilometers west of the Brantford town centre, services a small population of residential and industrial water users. A single well (Airport Well 1) historically supplied the full demand of the service area. A second well (Airport Well 2) was installed in 2014 to meet future demand and provide redundancy to the water distribution system. Earthfx was retained by the GRCA on behalf of the County of Brant to delineate the wellhead protection area (WHPA) and assign vulnerability scores for the Brantford Airport wellfield using a three-dimensional groundwater flow model.
