Abstract
Perry Canyon is an abandoned mine site 32 miles North of Reno, Nevada. The site faces environmental challenges within its stream system from historic copper mining activities. These include acidic drainage and erosion of acid-generating waste rock.
Our focus, given the contamination and erosion issues in Perry Creek, is to propose a streambank stabilization design for surface water restoration. This solution involves regrading the stream channel, laying erosion control fabric, and applying riprap to prevent further erosion. Additionally, a riparian buffer of native vegetation will be established to stabilize the area and reduce pollutant runoff. Working alongside a chemist at The University of Nevada, provisions are also being made for a water treatment system. This design aims to provide a sustainable, cost-effective solution to mitigate environmental risks while allowing natural processes to improve groundwater quality over time. The closure plan includes ongoing maintenance and monitoring, with regular water testing and erosion surveys to ensure the system's long-term stability and ecological health.
