Owned and operated by the Township of South Glengarry, the Glen Walter Water Treatment Plant is located on County Rd.2, approximately 2 km east of Cornwall. Municipal water is drawn from the St. Lawrence River and the intake is located approximately 390 m off shore, at a depth of 8 m. The system is designed to serve a population of 1,080 people and currently services approximately 850 through 350 service connections. This drinking water system is one of 13 systems that draw water from surface water in the form of rivers or lakes in the Raisin-South Nation Source Protection Region.
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.
