Isotopic and environmental tracers for improved understanding of geochemical and hydrologic processes occurring near flooded mine workings
Draining mine tunnels contribute metals and acidity to streams throughout the western United States. One remediation strategy that is increasing in usage is the emplacement of hydraulic bulkheads to impound water within the subsurface. Potential secondary effects of bulkhead usage are difficult to quantify however because of the inherent complexity of most mountain hydrologic systems. In...
