Available in PDF, EPUB and Kindle. Book excerpt: No sooner had the EPA established the Superfund program in 1980 to clean up the nation’s toxic waste dumps and other abandoned hazardous waste sites, than a little Montana town found itself topping the new program’s National Priority List. Milltown, a place too small to warrant a listing in the U.S. Census, sat alongside a modest hydroelectric dam at the confluence of the Clark Fork and Blackfoot Rivers. For three-quarters of a century, arsenic-laced waste from some of the world’s largest copper-mining operations had accumulated behind the dam. Soon, Milltown became the site of Superfund’s first dam removal and watershed restoration, marking a turning point in U.S. environmental history. The story of this dramatic shift is the tale of individuals rallying to reclaim a place they valued beyond its utility. In Restoring the Shining Waters, David Brooks gives an intimate account of how local citizens—homeowners, university scientists, county health officials, grassroots environmentalists, business leaders, and thousands of engaged residents—brought about the removal of Milltown Dam. Interviews with townspeople, outside environmentalists, mining executives, and federal officials reveal how the everyday actions of individuals got the dam removed and, in the process, pushed Superfund to allow more public participation in decision making and to emphasize restoration over containment of polluted environments. A federal program designed to deal with the toxic legacies of industrialization thus became a starting point for restoring America’s most damaged environments, largely through the efforts of local communities. With curiosity, conviction, and a strong sense of place, the small town of Milltown helped restore an iconic western river valley—and in doing so, shaped the history of Superfund and modern environmentalism.

S. Heth and published by . This book was released on 2015 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Disturbance is a dominant force in streams, and macroinvertebrates have adapted by using specialized strategies to reach refugia. Refugia include stable environments with abundant shelter and food resources. In the Missouri Ozarks, spring-fed tributaries are possible refugia. To determine if spring-fed tributaries serve as thermal refugia, submergent bidirectional movement was measured from spring-fed and surface-fed confluences in the Current River, Missouri during winter and summer. Macroinvertebrates were sampled to capture standing and bidirectional movement. Macroinvertebrate communities in summer significantly differed and formed three groups: surface-fed tributaries, Current River main channel, and spring-fed tributaries as supported by nonparametric analyses. Spring-fed tributary macroinvertebrate communities were distinct, which suggests these tributaries are unlikely thermal refugia for macroinvertebrates. Because greatest community differences existed between tributary types, mesohabitats were investigated. Mesohabitats differed in community composition and taxonomic richness within functional feeding groups with marginal vegetation having high taxonomic richness. Chironomidae among mesohabitats were analyzed because of their high diversity and density in streams. At the genus level, the inclusion of chironomids in analyses did not alter bioassessment metrics although chironomids alone were able to differentiate among mesohabitats reflecting differences found by the entire macroinvertebrate community. The most abundant chironomid taxa related best to nutrients and sediments. Further work with Chironomidae at the species level could improve environmental assessment and interpretation. The mesohabitat scale was able to differentiate among macroinvertebrate communities and should be further investigated in the Ozarks.

This book was released on 2016 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans have altered flow regimes of river systems worldwide. Restoration efforts are growing in an attempt to rehabilitate these modified systems. The ecological effects of alteration and restoration are not yet well understood due to a scarcity of monitoring over a wide range of environmental conditions. I examined macroinvertebrate community structure across four summers, ranging from record flood conditions to extreme drought, in a heavily altered system that is being considered for a flow restoration project. Due to a diversion channel and leveeing, the Cache River in southern Illinois is currently divided into the upper Cache River (UCR), which suffers from erosion and channel incision, and the lower Cache River (LCR), which is impaired by sedimentation and hypoxia. Resource managers are investigating the possibility of restoration via partial reconnection of the UCR and LCR. The Cache River experienced a large flood in 2011 and extreme drought conditions in 2012. I compared macroinvertebrate abundance, biomass, diversity, and community structure during June, July, and August of 2010-2013. Dissolved oxygen, temperature, chlorophyll, and discharge were also measured to aid in mechanistic interpretation. The UCR community had lower abundance (p = 0.04) and higher individual invertebrate body size (p = 0.03) than the LCR, and total biomass did not differ between the two river segments (p = 0.34). Macroinvertebrate community structure differed between the UCR and LCR (p = 0.001) and among years (p = 0.001). The UCR had higher Shannon diversity (p = 0.02) and lower Hilsenhoff Biotic Index (HBI) scores (p
