Interactive effects of multiple stressors and restoration priorities in a mined Appalachian watershed

“…Similarly, conditions immediately below the APS were extremely poor in fall 2002. However, chemical and biological conditions downstream Overall, our results are consistent with numerous studies documenting negative impacts of mining-related discharges (e.g., Cain et al, 2000;Soucek et al, 2001a;DeNicola & Stapleton, 2002) and thermal pollution (e.g., Poff & Matthews, 1986;Lauritsen & Starkel, 1989;Wellborn & Robinson, 1996) on water quality and aquatic organisms. The dominant effect of these stressors is to reduce invertebrate numbers, diversity, and richness to a few tolerant taxa (Cherry et al, 2001;DeNicola & Stapleton, 2002;Schmidt et al, 2002).…”

“…However, macroinvertebrates also were collected from leaf bags, artificial snags, macrophytes, natural substrates, and drift at some stations. Details of sampling methods can be found in Specht et al (1984), , , Lauritsen and Starkel (1989), and . Most of the data in this summary is from the 1984-1985 sampling period because fewer stations were sampled in the other years.…”

“…Because C Reactor, which discharged to Fourmile Branch, was placed on cold standby in June 1985, these data primarily represent the macroinvertebrate community that existed when C Reactor was operating at full power; however, the data also document early recovery of thermal stations between June and September 1985. After C Reactor shut down in June 1985, Lauritsen and Starkel (1989) .…”

Environmental summary of the F- and H-area seepage basins groundwater remediation project, Savannah River site

“…Gladden (1988) concluded that the macroinvertebrate community in Fourmile Branch was similar to the trophic structure of macroinvertebrate communities in upper Pen Branch and Meyers Branch, both of which have not been adversely affected by SRS operations. Lauritsen et al (1989) examined macroinvertebrates in Fourmile Branch between June 1985 and September 1987 as part of a larger study of SRS streams. They found that following the shut down of C-Reactor, recolonization of the stream by macroinvertebrates began within a month and proceeded rapidly.…”
