Book Description
Excerpt from The Examination of Waters and Water Supplies In this edition various sections have been amplified, one or two almost entirely re-written, and two additional ones added. Extended experience has enabled me to write with increased confidence of the modes of procedure and methods of analysis recommended, and, whilst the opinions of others may be freely quoted, everything recommended is based upon personal experience. The edition has had to be revised at a time when my leisure was very limited, and considerable intervals have, on occasions, elapsed between the revision of one section and another, and it is possible that a little repetition may have resulted. If such is found to be the case, it will probably be in connection with some point which I have thought it desirable especially to emphasise, and may therefore need no excuse. Many persons who have found the book useful have kindly sent mo suggestions. These have all been carefully considered; but the majority are not referred to, as they were either not germane to the subject or did not appear to be of any practical use. My one endeavour has been to make the work as practical and useful as possible. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Water is the most basic need of mankind. Drinking water is considered the most essential use of water in life. Therefore it must be free of pathogens, toxins and carcinogens. Absolutley pure water does not exist in nature. Surface water absorbs particles, carbon dioxide and other gases and mixes with silt and inorganic matters from the environment. When treated and untreated domestic and industrial waste is discharged into natural bodies of water the situation becomes even more complex. Thus human waste, drinking water and communicable diseases are directly related. Water contamination is measured by the level of pollutants present in a sample. Regular analytical estimation of wastewater is the answer. This manual emphasizes the importance of water purity for drinking and domestic purposes, different types of water and their utilization in various activities, the water quality requirements and criteria of International and Governmental Agencies, and simple estimation procedures and the significance of each analytical test. Quality Assessment of Water and Wastewater describes methods for ascertaining the quality and contamination levels of waters from a range of sources like ground, surface, potable water supplies, marine, beaches, swimming pools and other recreational facilities, and domestic and industrial wastewater. It includes important derivatives used in the preparation of standard solutions, data analysis, interpretation and units of expressions of the results. It also discusses all major pollutants - their origins and impact on the environment and health - with the basic chemistry of their analysis and complete methodology explained systematically.

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.
