Download or read book Urban wastewater Reuse for Crop Production in the Water short Guanajuato River Basin Mexico written by Christopher Anand Scott and published by IWMI. This book was released on 2000 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: From a river-basin perspective, wastewater irrigation is an important form of water and nutrient reuse; however, there are important water quality, environmental, and public health considerations. This report explores the advantages and risks of urban wastewater reuse for crop production in the water-short Guanajuato river-basin in west-central Mexico, and then by a selective literature review demonstrates how common this practice is worldwide. It also evaluates several alternative water-management scenarios through application of the Interactive River Aquifer Simulation (IRAS) model, developed by Cornell University and Resource Planning Associates.

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.

Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-08-17 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

This book was released on 2000-02-17 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading.
