Oneida #1

Oneida #1

The CCRA and partner organizations first received funding for and constructed a $350,000 treatment system for the Oneida #1 discharge location within the Eagle Rock Resort community. This simplistic system diverts approximately 2,500 gallons per minute (GPM) of acid mine drainage through three buried beds totaling 9,000 tons of high grade limestone.

Audenreid Tunnel

The success of oneida #1 project resulted in the construction of a $2,100,000 system for the Audenreid mine discharge. This system treats up to 9,000 gpm of acid mine drainage by passing it through three large concrete tanks that contain a total of 20,000 tons of limestone.

Oneida #3

A third smaller system has been constructed to treat the Oneida #3 discharge. All three systems include detention / sedimentation ponds to collect aluminum. Aluminum, in an acidic water soluction, is harmful to most forms of aquatic life. by eliminating the acidity, these systems also collect and eliminate the aluminum.

Continued Improvement

Plans are undeway to identify sources of water infiltration into the mines so that these sources can be eliminated. Although there is no way to keep normal ground water from entering the mines, it is possible to put streams back onto the surface that currently enter old workings and then exit through the five drainage tunnels by keeping this water on the surface, we can permanently increase the amount of clean water that enters the Catiwissa while reducing the amount of treated water.
