SOURCE CONTROL BEFORE RESTORATION
Offsets, Remediation and Bioremediation Are Different Tools
— and They Must Be Used in the Right Order
Across Canada, governments, industries and community organizations spend millions of dollars restoring fish habitat, rebuilding shorelines, creating wetlands and compensating for habitat lost to development.
Much of that work is necessary and worthwhile.
But there is a basic problem in the way some projects are planned and described:
A habitat offset, a remediation project and a bioremediation project are not the same thing.
They can happen at the same location. They can support one another. A remediated industrial shoreline can eventually become excellent fish habitat. A constructed wetland can treat polluted runoff while also providing habitat.
But each tool begins with a different purpose:
An offset compensates for unavoidable new environmental damage.
Remediation corrects or manages an existing environmental problem.
Bioremediation uses living systems to help treat that problem.
Restoration rebuilds ecological function.
The trouble begins when these separate jobs are bundled together and the whole package is called an offset.
