This book was released on 2006 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data from water quality monitoring conducted between October 2000 and September 2004 is presented to demonstrate the way that agricultural land use influences phosphorus concentrations in streams and rivers. This research brief discusses the nature of phosphorus pollution from agriculture along the Central Coast, examines the implications of these data for agricultural regulations, and offers suggestions for reducing phosphorus losses from farmlands.

This book was released on 2019 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-point source pollution (NPS), especially from agricultural runoff, is a leading contributor to water quality impairments in the U.S. Lately, attention to nutrient pollution, specially to phosphorus, has arisen due to disturbing increases in seasonal toxic blue-green algal blooms. To improve our understanding of how land use and seasonal weather patterns impact runoff and nutrient loading in temperate areas, we investigated the effect of different land uses on P inputs into Owasco Lake, in central NY. In addition, the inputs were evaluated in the context of a prolonged drought that affected the northeastern U.S. during 2016. Monitoring of base and high flow conditions was conducted between December 2015 and November 2016 at sites located along twelve tributaries to the lake, representing the dominating land uses in the watershed (i.e.: agriculture and forest). Small watersheds were chosen to be able to isolate impacts of particular land uses. The results show a strong interaction of seasonal and land use effects, with the drought event masking the effect of agricultural and mixed land use on P loads; and with the highest loads registering during the first rain event after the drought, exacerbating the agricultural impact on water quality. These findings are an important contribution from a management perspective, as projections for the Northeast US suggest that, although total precipitation will remain relatively stable, summer rains are likely to become concentrated in fewer events of higher intensities, interspaced with more prolonged dry periods. We consider it absolutely critical to incorporate detailed timing management practices for fertilizer and/or manure application relative to runoff producing storm events, in order to mitigate climate extremes impact on water quality.

This book was released on 1986 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Section 304(a) (1) of the Clean Water Act 33 U.S.C. 1314(a) (1) requires the Environmental Protection Agency (EPA) to publish and periodically update ambient water quality criteria. These criteria are to accurately reflect the latest scientific knowledge (a) on the kind and extent of all identifiable effects on health and welfare including, but not limited to, plankton, fish shellfish, wildlife, plant life, shorelines, beaches, aesthetics, and recreation which may be expected from the presence of pollutants in any body of water including ground water; (b) on the concentration and dispersal of pollutants, or their byproducts, through biological, physical, and chemical processes; and (c) on the effects of pollutants on biological community diversity, productivity, and stability, including information on the factors affecting rates of eutrophication and organic and inorganic sedimentation for varying types of receiving waters. In a continuing effort to provide those who use EPA's water quality and human health criteria with up-to-date criteria values and associated information, the document was assembled. The document includes summaries of all the contaminants for which EPA has developed criteria recommendations.

Download or read book Society and the Environment written by Michael Carolan and published by Routledge. This book was released on 2018-05-15 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Society and the Environment examines today's environmental controversies within a socio-organizational context. After outlining the contours of 'pragmatic environmentalism', Carolan considers the pressures that exist where ecology and society collide, such as population growth and its associated increased demands for food and energy. He also investigates how various ecological issues, such as climate change, are affecting our very own personal health. Finally, he drills into the social/structural dynamics (including political economy and the international legal system) that create ongoing momentum for environmental ills. This interdisciplinary text features a three-part structure in each chapter that covers 'fast facts' about the issue at hand, examines its wide-ranging implications, and offers balanced consideration of possible real-world solutions. New to this edition are 'Movement Matters' boxes, which showcase grassroots movements that have affected legislation. Discussion questions and key terms enhance the text's usefulness, making Society and the Environment the perfect learning tool for courses on environmental sociology.
