The Desired Future

What’s Next?

What to know:

The long-term end goal of the sub-surface remediation is to have a low maintenance, passive treatment system in place that treats acid mine drainage enough to achieve aquatic life standards where mine discharge enters Left Hand Creek. However, the interim water quality goals while the remediation activities are being tested and implemented are to maintain historic conditions prior to the work. This means that there may be impaired sections of the creek during remediation activities. For this reason, the Left Hand Watershed Center is working closely with the EPA, CDPHE, and their contractors to monitor water quality and ensure that we understand and are prepared to respond to the impacts of the activities on downstream water quality.
