Who Will Pay for the EPA's Mistake?

摘要

This month, E&MJ devotes a significant amount of coverage to environmental management, looking at two examples where two companies used their engineering expertise to reduce mining's impact on rivers. In "Remediation Helps Rescue a River," Steven Lange discusses the geology of Colorado's San Juan Caldera (cover photo) and the impact of Sunnyside Gold Corp.'s reclamation activities on the Animas River watershed. Due to the regional geology, heavy metals have been leaching into this watershed for millions of years. That same geology attracted miners and the abandoned mines have exacerbated the problem. In the relatively short period of time that Sunnyside Gold Corp. operated, their reclamation activities lessened the environmental impact from some of those abandoned mines significantly.
