The Town of Morrisburg municipal intake is located at the south end of Augusta Street toward the west of the town limits, in the St. Lawrence River. Raw water is drawn from approximately 2.75 m off the river bottom. The normal depth of water over the intake is estimated to be 8 m. The South Dundas Regional Water Treatment Plant is owned by the Township of South Dundas and is operated by Caneau Water and Sewage Operations Inc. This municipal water system services the villages of Morrisburg and Iroquois respectively and provides drinking water to the approximately 3,938 residents of these two communities.
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.
