Leadville Drain

A large scale pilot plant was operated at the drainage tunnel near Leadville, Colorado. The primary contaminating metals in the drainage were copper and zinc. During the pilot test, a 100,000 gallon quantity of contaminated mine drainage water was Octolig MRP treated. The average influent and effluent concentrations were:

Metal Untreated Water Octolig Treated Water

Cu           12.5 ppm                     .29 ppm

Zn           7.2 ppm                       .50 ppm

This plant-scale pilot test proves that Octolig treatment reduces heavy metal concentrations to concentrations of parts per billion.
