Gumtree Waste Pile
The lower Gumtree waste pile had eroded severely into Trail Creek. This blow out was repaired and regraded. All materials were consolidated and regraded for positive drainage. The mine waste piles were amended to stabilize pH and limit the mobility of heavy metals. The mine waste piles were then amended with compost to provide a growth media to the waste piles to assist with the revegetation process.
The objective of the project was to contribute to the reduction of total metal loading in Trail Creek and removing Trail Creek from State of Colorado 303(d) list of impaired waters.
