Well Installation & Completion in Clearview Township

Well installation in Clearview Township is defined by the need to properly seal well casing into shallow fractured limestone bedrock. With overburden often measuring just one to five metres, the casing-in-rock seal becomes the most critical element of the entire installation because it is the primary — and in some cases the only — barrier between the surface environment and the drinking water aquifer. The fractured limestone bedrock that underlies Clearview is an excellent aquifer when properly accessed, but those same fractures near the surface can channel contamination into the groundwater if the well seal is not executed correctly. Our installation protocol for Clearview begins with advancing the casing through the thin overburden and into a competent section of bedrock below the weathered and fractured surface zone. Neat cement grout is then placed from the bottom of the annular space upward, filling every void between the casing and the rock. We verify the fill by tracking grout volume against the calculated annular capacity. Once the seal is confirmed, the well is developed by pumping to clear drilling debris from the bedrock fractures that supply water. The pump is set at a depth determined by the pump test results, with adequate submergence below the anticipated drawdown level. Given the vulnerability of shallow bedrock aquifers to surface contamination, we pay particular attention to the wellhead completion — the cap, the surface grading, and the above-grade casing extension all contribute to keeping contaminants out of your Clearview well.
