Surface Remediation Completed

What to know:

The surface remediation occurred from 2011 to 2013. This work aimed to reduce human exposure to harmful toxins in the tailings and other waste materials, and reduce exposure of tailings and waste to groundwater and surface water runoff. To achieve this, waste rock and material were consolidated into two cells within superfund project area. These areas have established surface water diversions to minimize runoff contact, are buried with soil, and are overseeded with native vegetation. This work was overall successful- threats have been greatly reduced and the landscape is well established with grasses. The area was only minorly impacted by the 2013 September floods.
