Protecting groundwater during hydraulic fracturing

Depth of resource, regulations and industry best practices ensure groundwater resources are protected during hydraulic fracturing.

Drinking water aquifers are
usually found at depths less
than 300 metres. A well
that is hydraulically
fractured is typically drilled
at a depth of 2,000 to
3,000 metres, far below any
aquifers. 

As well, multiple layers of steel casing are inserted and cemented in place to create a
solid barrier between the wellbore and any underground water
sources.
