Sharing Your Bearings

Cleaning Up the Mess

Restoring Our Environment


Presenter:  Bruce Manchon

Event hosts: Wilson and Vicki Wiedenheft

Many of us are aware of human activities that have polluted our environment. We have heard of Superfund sites, that have been identified for cleanup because they pose risk to human health and/or the environment.


Using case studies, Bruce Manchon will introduce us to the world of site investigations, remediation processes and environmental clean-ups. He will present methodologies that are utilized to address the removal of contaminants from the earth’s soils, sediments, rocks, and both groundwater and surface water.

Currently, the EPA lists 24 Superfund sites on its National Priorities List (NPL) in Colorado. However, there are more than 200 total Superfund sites in Colorado, but only the 24 on the NPL have been identified as needing further assessment and cleanup.


Finally, regarding cleaning up the mess, we will consider the potential environmental consequences of the fact that, 'if we do not change direction, we will end up where we are heading.'
