The Lancaster Water Treatment Plant is owned and operated by the Township of South Glengarry and is located approximately 1 km downstream from the Village of Lancaster on Old Montreal Road. It serves a population of 1,218 with 406 service connections. Municipal water is taken from Lake St. Francis, part of the St. Lawrence River. The intake is located southeast of Faulkner’s Point, approximately 1,300 m offshore, at a depth of approximately 8 m, nearly 2 m off the bottom of the lake.
The vulnerability score is a representative measure of the drinking water source's susceptibility to contamination due to the nearby physical landscape (ratio of land to water in the area, land cover, soil type, and hydrological and hydrogeological conditions in the area) and the physical conditions at the intake (depth of the intake, distance from land, past drinking water issues).
Higher values indicate a higher level of concern for contamination. Intake Protection Zones (IPZs) are the areas where policies may apply to protect drinking water sources. IPZ-1 is the zone immediately near the intake. IPZ-2 is an area based on the response time required to react to a reported spill.
