water well decommissioning

If an unused well exists on your property and the old well has not been properly decommissioned (ie. abandoned), it poses a risk of contamination to the aquifer below and thus, to the water being accessed by the new well and any surrounding wells. In other words: it puts your drinking water and your neighbours’ drinking water at risk.

A well becomes problematic when contaminants (like bacteria from surface water or septic effluent, pesticides, fertilizers, etc.) enter it through...

• the surface opening, if the well cap is loose, cracked, improper, or missing.

• the unsealed spaced (the annulus) between the outside of the casing and the ground.

• corroded sections of casing. 

There are government regulations to ensure the proper decommissioning of water wells; read them and/or contact me to discuss your options.
