“…Bioassessment procedures have been used to evaluate aquatic systems impacted by environmental disturbances such as timber harvest (Williams, Warren, & Clingenpeel, 2002), industrial discharges (Diamond, Bressler, & Serveiss, 2002), and mine drainages (Soucek, Cherry, Currie, Latimer, & Trent, 2000;Cherry, Currie, Soucek, Latimer, & Trent, 2001;Grout & Levings, 2001;DeNicola & Stapleton, 2002). Research has been conducted on an array of coal mining impacts ranging from stream acidification (Guerold et al, 2000), sedimentation (Bonta, 2000), heavy metal influx (Clements, Carlisle, Lazorchak, & Johnson, 2000), and metals mobilized by acid mine drainage (AMD) (Cherry et al, 2001;Soucek, Schmidt, & Cherry, 2001a).…”
