Available in PDF, EPUB and Kindle. Book excerpt: Since the 1950s, the housing developments in the West that historian Lincoln Bramwell calls “wilderburbs” have offered residents both the pleasures of living in nature and the creature comforts of the suburbs. Remote from cities but still within commuting distance, nestled next to lakes and rivers or in forests and deserts, and often featuring spectacular views of public lands, wilderburbs celebrate the natural beauty of the American West and pose a vital threat to it. Wilderburbs tells the story of how roads and houses and water development have transformed the rural landscape in the West. Bramwell introduces readers to developers, homeowners, and government regulators, all of whom have faced unexpected environmental problems in designing and building wilderburb communities, including unpredictable water supplies, threats from wildfires, and encounters with wildlife. By looking at wilderburbs in the West, especially those in Utah, Colorado, and New Mexico, Bramwell uncovers the profound environmental consequences of Americans’ desire to live in the wilderness.
Download or read book City Dreams Country Schemes written by Kathleen A. Brosnan and published by University of Nevada Press. This book was released on 2013-10-11 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: The American West, from the beginning of Euro-American settlement, has been shaped by diverse ideas about how to utilize physical space and natural environments to create cohesive, sometimes exclusive community identities. When westerners developed their towns, they constructed spaces and cultural identities that reflected alternative understandings of modern urbanity. The essays in City Dreams, Country Schemes utilize an interdisciplinary approach to explore the ways that westerners conceptualized, built, and inhabited urban, suburban, and exurban spaces in the twentieth century. The contributors examine such topics as the attractions of open space and rural gentrification in shaping urban development; the role of tourism in developing national parks, historical sites, and California's Napa Valley; and the roles of public art, gender, and ethnicity in shaping urban centers. City Dreams, Country Schemes reveals the values and expectations that have shaped the West and the lives of the people who inhabit it.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ore Knob Copper Mine located near Jefferson, North Carolina, operated from 1850 to 1962;mine tailings from the mine were disposed of behind an earthen dam located in the headwaters of Ore Knob Branch, a tributary to Peak Creek. As a result of groundwater contamination, the EPA placed the mine on the National Priority List in 2009. The erosion of mine tailings also released toxic trace metals to Peak Creek, where they were transported to the South Fork New River, an important recreational and ecological resource. The objectives of this study were to determine the source of metals in the South Fork New River and their potential impact(s) on aquatic biota by (1) documenting metal concentrations, and their spatial variations, in water and sediment along the river to locate potential sources, and (2) comparing these metal concentrations to previously developed aquatic effect criteria. Geochemical analyses included the determination of both total and bioavailable concentrations of aluminum, cobalt, copper, iron, and zinc in channel bed sediment as well as their dissolved and total recoverable concentrations in water along a 33km reach of the South Fork New River. Water and sediment samples were also collected from surrounding tributaries, including Peak Creek. Metal concentrations in Peak Creek, below the mine, were relatively high and decreased downstream, indicating that some metals were delivered to the South Fork New River. However, metal concentrations in both water and sediment varied significantly along the river and did not abruptly increase downstream of Peak Creek. These spatial trends suggest that the Ore Knob mine and Peak Creek (which was once devoid of fish) no longer contribute significant quantities of metals to the South Fork New River. Downstream variations in sediment-associated metal concentrations appear to reflect, in part, localized fine-grain sediment deposition, differences in organic carbon content, and the exposure of bedrock outcrops from which sulfidic minerals can be eroded. Comparison of dissolved metal concentrations in water to EPA guidelines found that no sampling sites exceeded acute nor chronic limits. In contrast, numerous (56 %, 94%) of the sampling sites exceeded the NCDEQ total recoverable concentration limits (120 ppb, 7 ppb) for Zn and Cu, respectively. A total of two sites exceeded the threshold effect concentration (TEC) for sediments compiled for Zn by MacDonald et al., whereas 3 sites exceed the TEC for Cu. The various criteria used herein suggest differing potential impacts of the metals on aquatic biota along the South Fork New River. However, the bioavailability of the metals is an important consideration. Dissolved concentrations in water, which indicated limited potential impacts, represent highly bioavailable metals. In contrast, metals attached to sediments both on the channel bed and within the water column may in part, be non-bioavailable, particularly given that the metals are largely derived from sulfidic mineral layers in the bedrock. Thus, the impacts to aquatic biota is likely to be limited.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hard rock and placer mining have been occurring throughout the mountains in the northern portion of Washington State since the late-1800s. As a result, aquatic ecosystems in this region are susceptible to the physical, chemical and biological changes that result from mining activities. These alterations, which include changes in water chemistry, habitat modifications, and reduction or contamination of food sources, can adversely impact aquatic communities of periphyton, benthic macroinvertebrates and fish. To evaluate changes in water chemistry and biological communities in two regions with extensive mining histories, the Ruby Creek watershed and Upper Skagit River watershed, I analyzed metals in grab samples of surface water, on Stabilized Liquid Membrane Devices (SLMDs) which passively sample metals in surface waters over time, and in periphyton. Metals were present in the water and benthos, and site-specific and temporal differences in the kinds and quantities of metals were linked to locations of hard rock and placer mining activities. Metal concentrations in surface waters differed between sites upstream and downstream of mining depending on different times when mining was or was not occurring. Metal concentrations in surface waters at some sites in the Ruby Creek watershed were high enough to be capable of adversely affecting aquatic organisms over time. Metals that were present in streams were not always detected in grab samples, but their presence was confirmed by SLMDs and periphyton. Clustering analyses of both SLMDs and periphyton each distinguished two different groups of samples, samples collected downstream of placer mining (SLMDs) and samples collected downstream of hard rock mining (periphyton). The accumulation of metals in periphyton indicated these communities could be a concentrated source of toxic metals to primary consumers, such as small aquatic insects, and may pass to other aquatic organisms at higher trophic levels through dietary exposures
