Activities in 'Colorado'

Argo Tunnel, Clear Creek County
description: A 3-year cooperative demonstration of the pulsed limestone bed treatment technology developed by the USGS was begun here in 2004, in cooperation with the Mine Waste Technology Program of EPA, the Colorado School of Mines and the state of Colorado. Preliminary test results show effective removal of iron and aluminum, leading to a decrease in the amount of base needed to remove other metals present in the discharge.
