AB  - Over 4000 km of Pennsylvania's flowing waters and attendant ecosystems have been 
      degraded by mine drainage to the exclusion of multiple designated uses. Both Acid 
      Mine Drainage (AMD) and Net Alkaline Mine Drainage (NAMD) may result from coal 
      extraction depending on the underlying geology. Acid Mine Drainage is 
      characterized as an acidic mixture of toxic heavy metals in solution, while NAMD 
      is circumneutral in pH with metals forming oxidized precipitates. The ecological 
      impacts of AMD have been well documented but NAMD-impacted streams have received 
      considerably less attention. We selected 10 low-order tributaries of the Ohio and 
      Youghiogheny rivers in southwestern Pennsylvania impacted by point-source inputs 
      of NAMD for assessment of water quality and benthic macroinvertebrate 
      communities. Levels of pH, total iron (Fe), and sulfate (SO(4)) were 
      significantly elevated in the impacted stream reaches when compared with upstream 
      reference sites while total alkalinity and specific conductance were equivalent. 
      Macroinvertebrate abundance declined by 92% in the impacted stream reaches, but 
      community structure in terms of taxonomic composition and species richness was 
      similar. Total iron, total sulfate, and specific conductance were significantly 
      linked to macroinvertebrate community impairment. The presence of resident 
      macroinvertebrate communities in the unimpacted reaches suggests that remediation 
      would result in a rapid recolonization and establishment of viable downstream 
      ecosystems.
