Drill core wells for hydrogeological study in southern Ontario.
Natural Resources Canada (NRCan) seeks a contractor to drill core wells for a hydrogeological characterization project in the Lower Grand River watershed (~2000 km²) in southern Ontario. The project involves drilling boreholes at four sites (with an option for three more) and converting them into environmental monitoring wells. Wells will be either PQ overburden cored holes with monitoring wells or HQ rock cored monitoring wells, with total drilled depths up to 50 m (or 65 m for two deeper wells). Work must begin the third week of September 2026. The contractor must provide well drilling and construction services, including downhole drilling tool services and water well drilling services.
