Book Description
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.

Book Description
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.

Book Description
Water quality monitoring is an essential tool in the management of water resources and this book comprehensively covers the entire monitoring operation. This important text is the outcome of a collborative programme of activity between UNEP and WHO with inputs from WMO and UNESCO and draws on the international standards of the International Organization of Standardization.

Book Description
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.

Book Description
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.
