    Figure S1. (Left) Aerial view of a southern West Virginia (WV) mountaintop mining site with valleyfills. [photo by Paul Corbit Brown] (Right) Perennial streams below a Kentucky valley fill (top)[photo by Ken Fritz] and a WV valley fill (middle) [photo by Jack Webster] show visible pollutionfrom trace metals. Unimpacted perennial streams such as this one in WV have generally clearwater and are without metal deposits on the streambed such as those in the two photos above(bottom) [photo by Jack Webster].

    West Virginia stream condition index (WVSCI) scores were calculated using family level identification ofmacroinvertebrates, which is why there are more records for WVSCI scores than there are for genuslevel counts within each category. Determinations of tolerance were made by staff of the WVDEPaccording to WV stream condition index (S3) guidelines. Excerpted from that document (p. A-5):Tolerance of a taxon is based on its ability to survive short- and long-term exposure to organic

    pollution. The Hilsenhoff Biotic Index (HBI) weights each taxon in a sample by its proportion ofindividuals and the taxons tolerance value. Following the basic framework established by Hilsenhoff(S4), tolerance values were assigned to individual taxa on a scale of 0-10, with 0 identifying those taxaleast tolerant (most sensitive) to stressors, and 10 identifying those taxa most tolerant (least sensitive)to stressors. Tolerance values compiled by USEPA (S5) and Merritt and Cummins (S6) were used forthis analysis.
