How can I protect my water supply?
By Mike Lockhard, Hydrogeologist, Alberta Environment

You can protect your water supply by carefully managing activities near the water source. For households using a domestic well, this includes keeping contaminants away from drainage holes and the well itself. Hazardous chemicals also should be kept out of septic systems.

The following diagram shows the minimum distance that potential contaminant sources should be kept from a water well. These separation distances are stipulated in Alberta Environment’s Water Well Regulation.
