| At the Summitville Mine site in Colorado, highly contaminated water runs through an abandoned mine shaft. The investigation that is underway focuses on the presence and nature of fractures in the adjacent rock where the water could migrate, leach metals, and eventually contaminate the environment downstream. Engineers at the site believe plugging the shaft can control the contaminant flow leaving the mine while inhibiting the leaching process. In this presentation, the Environmental Response cameras highlight the challenges of solving the environmental problems at this site. Running time is 10 minutes. |
