Stream water chemistry and benthic macroinvertebrate data from the North Fork Clear Creek and Clear Creek, Colorado, USA, from 2011-2019, before and after acid mine drainage treatment

Stream water chemistry and benthic macroinvertebrate data collected in the North Fork of Clear Creek and Clear Creek, CO, USA before and after the diversion and treatment of acid mine drainage by a high-density sludge lime process water treatment plant. Stream water chemistry and benthic macroinvertebrate samples were collected from November 2011 through October 2019 at 6 sites located above and b

Integrated assessment of chemical and biological recovery after diversion and treatment of acid mine drainage in a Rocky Mountain stream

Responses of stream ecosystems to gradual reductions in metal loading following remediation or restoration activities have been well documented in the literature. However, much less is known about how these systems respond to the immediate or more rapid elimination of metal inputs. Construction of a water treatment plant on the North Fork of Clear Creek (NFCC; CO, USA), a US Environmental Protecti
