Restoration can improve mining contamination, indicates study

Restoration can improve mining contamination, indicates study Mining involves moving a lot of rock, so some mess is expected. However, mining operations can continue to affect ecosystems long after activity has ended. Heavy metals and corrosive substances leach into the environment, preventing wildlife and vegetation from returning to the area. Fortunately, this damage can be reversed. A team of scientists, including UC Santa Barbara s Dave Herbst, investigated how river ecosystems respond to remediation efforts. The team combined decades of data from four watersheds polluted by abandoned mines. It took creative thinking to simplify the complex dynamics of nearly a dozen toxins on the myriad species in each river.
