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.

Available in PDF, EPUB and Kindle. Book excerpt: National environmental quality objectives continue to be an important part of the Civil Works objective of the CE (Corps of Engineers) and continuing emphasis is placed on operating projects to meet these objectives. The EWQOS program has developed information and technology to meet these national environmental objectives in a manner compatible with authorized project purposes. This technology and knowledge on how reservoir and waterway projects respond to various design and operational scenarios will allow field officer personnel to solve current environmental quality problems and to rapidly respond to emerging problems in the future. Technology transfer efforts planned or underway will insure this information is available and will provide the necessary support for full implementation of EWQOS research results in a cost-effective manner. Technology transfer activities and information gained from EWQOS research will permit the CE to continue water resource management in harmony with national environmental quality objectives.

Download or read book Review of the New York City Department of Environmental Protection Operations Support Tool for Water Supply written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-01-11 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: New York City's water supply system is one of the oldest, largest, and most complex in the nation. It delivers more than 1.1 billion gallons of water each day from three upstate watersheds (Croton, Catskill, and Delaware) to meet the needs of more than eight million people in the City, one million people in Westchester, Putnam, Orange, and Ulster counties, and millions of commuters and tourists who visit the City throughout the year. The Catskill and Delaware portions, which make up about 90 percent of the supply, receive no filtration or treatment other than disinfection, except for rare instances of high turbidity when a coagulant is added to increase deposition of suspended solids. The remaining 10 percent of the supply comes from the Croton watershed and receives treatment via filtration. The drinking water supply is managed by the Bureau of Water Supply within the New York City Department of Environmental Protection (NYC DEP). To continue to avoid filtration of the Catskill/Delaware portion of the water supply, in 2007, NYC DEP reexamined its control of turbidity in the Catskill portion of the water supply, including both structural improvements to the system and operational changes. The Operations Support Tool (OST) was developed as part of these efforts. OST couples models of reservoir operations and water quality; it uses real-time data on streamflow, snow pack, water quality, reservoir levels, diversions, and releases; and it incorporates streamflow forecastsâ€"all in order to predict future reservoir levels, water delivery to customers, and water quality within the system. These predictions inform the system operators, who then make decisions based on the most current data and forecasts. This report reviews the use of OST in current and future reservoir operations. It considers potential ways in which the City can more effectively use OST, makes recommendations for additional performance measures, and reviews the potential effects of climate change on the City's water supply to help identify and enhance understanding of areas of potential future concern with regard to the use of OST.

This book was released on 1986 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques from the use of simple data displays to the application of nonparametric and multivariate statistics are presented. Methods of data display are presented as a means of becoming familiar with the data and presenting those data. Basic descriptive statistics are discussed as a means to summarize the typically large data sets that result from a water quality monitoring program. The application of inferential statistics to make sound conclusions about differences, relationships, or trends within the data is also discussed. All of these methods are presented with concise and clear examples using actual water quality data. The report also provides an introduction to the statistical concerns involved in sample design that are necessary for the proper execution of a water quality monitoring program.

Available in PDF, EPUB and Kindle. Book excerpt: The central objective of the EWQOS program is the development of new technology or procedures for the planning, design, construction, and operation of water resource projects to meet environmental quality objectives while simultaneously attaining authorized project purposes. It is interesting to note the close parallel between the theme for this seminar and the objective of EWQOS, which demonstrates the timeliness of R/D and its importance to water resource development for the CE. If one further delves into the topics covered by this seminar, other similarities related to the intrastructure of EWQOS and the objectives of specific R/D tasks are apparent. Within the seminar topics, field methods, mathematical modeling, water control procedures, and case studies are of preeminence. Key terms within these topics include compatibility, constraints, conflicts, objectives, and policy issues.

This book was released on 1987 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Environmental and Water Quality Operational Studies (EWQOS) program, a major water quality research program funded by the Office of the Chief, US Army Corps of Engineers (CE), and conducted by the US Army Engineer Waterways Experiment Station, was designed to assess the relations between design, construction, and operation of Civil Works projects and exhibited water quality characteristics, and to develop and demonstrate technological means for ameliorating water quality problems in a manner compatible with project purposes. An important aspect of the EWQOS Program was the conduct of comprehensive studies of water quality processes in reservoirs. These studies involved both long-term and short-term limological evaluations of four characteristic CE reservoirs. DeGray Lake, located in south-central Arkansas, was studied during the period 1967-1982. Research activities ranged from evaluations of geologic and hydrologic processes, to studies of complex biological, chemical, and physical processes influencing water quality, to the development of water quality models. A symposium was held to provide a forum for the exchange of information and ideas and an opportunity to synthesize these data in ways that will lead to a greater understanding of DeGray Lake, in particular, and of reservoir limology, in general. Information gathered as a result of these studies and discussed herein will broaden the understanding upon which sound strategies for managing these valuable resources must be based. This report documents information presented at the symposium. (Author).

This book was released on 1986 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: This instruction report identifies and discusses many of the downstream environmental quality effects of general reservior project operation, peaking hydropower operation, and flood control operation. Individual design and operation elements are identified, when possible, and the specific environmental effects of each are detailed under topic headings. Some of the topics addressed in this handbook include the effects of daily and weekly minimum low flows, effects of fall drawdown, effects of highly fluctuating flows, and relative effects of surface versus deep release. Each topic is defined and discussed; recommendations are presented which, in many cases, will alleviate the detrimental environmental quality effects of reservoir project operation.

This book was released on 1983 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: In October 1977, the Environmental and Water Quality Operational Studies (EWQOS) was initiated under the sponsorship of the Office, Chief of Engineers (OCE). The EWQOS was planned as a 6-year program of applied research to answer select, high-priority environmental quality problems associated with the Civil Works activity of the Corps of Engineers (CE). Rapid development of technology and changing priorities of research have expanded both the scope and the planned duration of the program to 8 years and a scheduled completion in fiscal year 1985. The program is managed for OCE by the Waterways Experiment Station (WES), Vicksburg, Mississippi. This paper will present the program in its present form and provide the status of the research to date.
