Filling an artesian well
In Québec, every artesian well owner is responsible for maintaining their water supply system. The Regulation respecting the withdrawal and protection of groundwater (RPEP) was established to protect groundwater resources by reducing the risk of contamination.
When an artesian well in Québec is no longer in use, it cannot simply be abandoned. Property owners are required to have the well properly sealed, a permanent procedure that eliminates potential contamination pathways and ensures compliance with provincial regulations.
Why Seal an Artesian Well?
An abandoned artesian well can become a direct pathway for contaminants to reach groundwater, putting drinking water quality at risk. Properly sealing an unused well helps protect the environment, preserves groundwater resources, and ensures compliance with Québec’s environmental standards.
The Artesian Well Sealing Process
The sealing of an artesian well must be carried out by qualified professionals in accordance with the requirements of the RPEP. The process generally includes the following steps:
- Excavate the well casing to a depth of approximately one metre below ground level.
- Cut the steel casing at the bottom of the excavation.
- Fill the portion of the borehole that is in contact with the geological formation using clean sand.
- Fill the remaining section of the steel casing with bentonite or a cement-bentonite mixture.
- Use only materials that will not adversely affect groundwater quality.
- Install a concrete cap over the top of the remaining steel casing.
- Backfill the excavation using the original excavated material.
Following these procedures ensures that the artesian well is permanently sealed in a safe, environmentally responsible manner while protecting groundwater resources for future generations.
