Book Description
Illuminating opportunities to develop a more integrated approach to municipal water system design, Natural and Engineered Solutions for Drinking Water Supplies: Lessons from the Northeastern United States and Directions for Global Watershed Management explores critical factors in the decision-making processes for municipal water system delivery. The book offers vital insights to help inform management decisions on drinking water supply issues in other global regions in our increasingly energy- and carbon-constrained world. The study evaluates how six cities in the northeastern United States have made environmental, economic, and social decisions and adopted programs to protect and manage upland forests to produce clean drinking water throughout their long histories. New York, New York; Boston and Worcester, Massachusetts; New Haven and Bridgeport, Connecticut; and Portland, Maine have each managed city watersheds under different state regulations, planning and development incentives, biophysical constraints, social histories, and ownerships. Some of the overarching questions the book addresses relate to how managers should optimize the investments in their drinking water systems. What is the balance between the use of concrete/steel treatment plants (gray infrastructure) and forested/grassland/wetland areas (green infrastructure) to protect surface water quality? The case studies compare how engineered and/or natural systems are employed to protect water quality. The conclusions drawn establish that it makes environmental, economic, and social sense to protect and manage upland forests to produce water as a downstream service. Such stewardship is far more preferable than developing land and using engineering, technology, and artificial filtration as a solution to maintaining clean drinking water. Lessons learned from this insightful study provide effective recommendations for managers and policymakers that reflect the scientific realities of how forests and engineering can be best integrated into effective watershed management programs and under what circumstances.

Book Description
New York City's municipal water supply system provides about 1 billion gallons of drinking water a day to over 8.5 million people in New York City and about 1 million people living in nearby Westchester, Putnam, Ulster, and Orange counties. The combined water supply system includes 19 reservoirs and three controlled lakes with a total storage capacity of approximately 580 billion gallons. The city's Watershed Protection Program is intended to maintain and enhance the high quality of these surface water sources. Review of the New York City Watershed Protection Program assesses the efficacy and future of New York City's watershed management activities. The report identifies program areas that may require future change or action, including continued efforts to address turbidity and responding to changes in reservoir water quality as a result of climate change.

Book Description
Aimed at helping drinking water utilities develop key relationships with the diverse users of the same environmental resources that utilities need to provide reliable supplies of high quality drinking water to customers, this AAWA-sponsored report contains tools and resources developed from ten utility case studies, surveys of 30 utilities, evaluation of the outcomes of two workshops, and literature reviews. It also offers an executive summary and 19 exhibits including such stakeholder alliance tools as guides, handbooks, and programs; institutional and regulatory programs and contacts; technical assistance; and financial assistance resources. Lacks an index. An erratum refers to report #90826 and credits the consulting firm. Annotation c. Book News, Inc., Portland, OR (booknews.com)

Book Description
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.

Book Description
Dissolved air flotation (DAF) is an increasingly applied technology for particle removal in water and wastewater treatment. In DAF tiny air bubbles attach to the particles, which float to the surface, forming flocs which can be periodically removed to a sludge channel. The technique originated in the early 1900s, but has steadily widened its application across municipal and industrial water and wastewater treatment, earning a reputation for reliability, controllability and effectiveness. The aim of the Helsinki conference was to provide an opportunity for researchers and practitioners to examine and discuss current developments and applications of DAF technology in water and wastewater treatment. From the 58 oral and poster presentations, 26 papers have been selected for these proceedings. The papers have been divided into four themes: drinking water treatment, wastewater treatment, industrial and trade applications, theory and modelling.

Book Description
It is widely known that microorganisms such as E. coli, Giardia and Cryptosporidium can enter streams during rain and snowmelt events. It is diffcult to accurately determine the magnitude and timing of transport during such events, and identifying the sources of these contaminants. Reports the results of a study where microbial and water-quality measurements were collected during storm events under a variety of meterological and land use conditions.
