Download or read book Water Reuse written by National Research Council and published by National Academies Press. This book was released on 2012-07-17 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expanding water reuse-the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation-could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.

Download or read book Hospital Wastewaters written by Paola Verlicchi and published by Springer. This book was released on 2017-09-04 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume addresses hospital effluents in terms of their composition and the management and treatment strategies currently (being) adopted around the globe. In this context, one major focus is on pharmaceutical compounds: their observed concentration range, ecotoxicological effects, and the removal efficiency achieved by the different technologies. Another focus is on management strategies (dedicated hospital wastewater treatment, or a combined approach also involving urban wastewater) and currently adopted treatments to reduce the released pollutant load. Innovative and promising technologies under investigation at the lab and pilot scale are presented. A discussion of remaining knowledge gaps and future research requirements rounds out the coverage. The respective chapters, written by experts in the different fields, provide useful information for a broad audience: scientists involved in the management and treatment of hospital effluents and wastewater containing micropollutants, administrators and decision-makers, legislators involved in the authorization and management of healthcare structure effluents, and environmental engineers involved in the design of wastewater treatment plants, as well as newcomers and students interested in these issues.

Download or read book Management of Legionella in Water Systems written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2020-02-20 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.

Download or read book Ground Water Recharge Using Waters of Impaired Quality written by National Research Council and published by National Academies Press. This book was released on 1994-02-01 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: As demand for water increases, water managers and planners will need to look widely for ways to improve water management and augment water supplies. This book concludes that artificial recharge can be one option in an integrated strategy to optimize total water resource management and that in some cases impaired-quality water can be used effectively as a source for artificial recharge of ground water aquifers. Source water quality characteristics, pretreatment and recharge technologies, transformations during transport through the soil and aquifer, public health issues, economic feasibility, and legal and institutional considerations are addressed. The book evaluates three main types of impaired quality water sourcesâ€"treated municipal wastewater, stormwater runoff, and irrigation return flowâ€"and describes which is the most consistent in terms of quality and quantity. Also included are descriptions of seven recharge projects.

Download or read book Choosing Disinfection Alternatives for Water Wastewater Treatment Plants written by Frank R. Spellman and published by CRC Press. This book was released on 1999-06-29 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safe drinking water and effluent have long been dependent on the large-scale use of chlorine. Process Safety Management (PSM) and the Risk Management Program (RMP), safety regulations now enforced by OSHA and EPA are leading to serious reconsideration of chlorination as the preferred disinfection method. Renewed concern about the safety of chlorination by-products is also driving water and wastewater specialists and plant personnel to consider alternatives to traditional chlorine application. Choosing Disinfection Alternatives for Water/Wastewater Treatment is a practical explanation of all available disinfection technologies in light of management criteria: legal compliance, plant safety, effuent quality, and cost. This text is designed for all who must understand and act on the challenge of finding safe and equally effective methods of wastwater and water disinfection besides traditional chlorination.

Download or read book Watershed Management for Potable Water Supply written by National Research Council and published by National Academies Press. 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.
