Project

Chaudiere

This activity corresponds to the NRCan's efforts focused on the assessment of the key Canadian aquifers, understanding their groundwater dynamics and development of numerical groundwater flow models to assess the sustainability of the groundwater resource. Located south of Quebec City, the Chaudière River Watershed encompasses an area of approximately 6,700 km2 and extends from the American border to the St. Lawrence River. In the southern part, the watershed is mainly forested and agriculture dominates the northern part. Approximately 65% of the population (~150,000) relies on groundwater as the main source of potable water. The regional aquifer consists of Appalachian sedimentary rocks at the base with recent coarse sediments occasionally distributed on top. Existing data for groundwater levels are closely correlated to the topography and fractured rock has relatively low hydraulic conductivity, 1x10-7 m/s. These findings suggest that the groundwater flow is controlled mainly by the local topography with negligible regional flow. The conducted chemical analyses of groundwater samples indicate groundwater of good quality relative to the drinking water standards.
