In addition to detailed instructions for sampling and immediate analysis, the book provides a concise presentation of both the theoretical background and data evaluation. The analytical methods thus presented can just as easily be applied using simple equipment as well as in the modern laboratory. The book is a bench-top laboratory manual and as such can be used for instruction in laboratory staff training programs. It treats the analysis of organic and inorganic compounds while also dealing with microbiological problems associated with the guidelines for waste, surface and ground water, as well as drinking water quality.

The aim of the book is to provide domain-specific text/reference material pertaining water chemistry/hydrogeochemistry catering to students of geology, hydrogeology, civil engineers, hydrochemistry and environmental sciences. It will also be very much useful to professionals involved in water supply, treatment, and researchers engaged in water chemistry. The book is intended to provide ample realistic examples on water quality pertaining to varied geological environs, which would help in easy understanding of concepts. Question bank and exercises with keys/answers are provided for each chapter, which would facilitate the readers to assess their understanding and also facilitate in competitive tests. The book covers all the topics related to water chemistry with emphasis on ground water. Interpretation techniques for major ion content of water are deliberated exhaustively. Procedure of preparation of plots, graphs and calculations of various indices both manually and using simple software are discussed in detail.

The study of the environment requires the reliable and accurate measurement of extremely small quantities of chemicals and the ability to determine if they are pollutants or naturally occurring species. Historically, a "dilute and disperse" method of waste disposal has been accepted; yet as we learn the long-term consequences of such an approach, it is clear that more rigorous waste management techniques are necessary to understand the sources and fates of contaminants and to regulate their discharge. This volume presents the details of the basic analytical science involved in making these measurements. It concentrates on the basic principles of sampling and sample preparation, followed by the chemical principles of the major instrumental methods used in chemical analysis, and detailed discussions of the major environmental matrices. This book also provides coverage of topics usually only partially discussed in textbooks, such as quality assurance plans and statistical data handling. Students majoring in environmental sciences need a foundation in measurement techniques used in the field. Environmental Chemical Analysis gives students a thorough grounding in this field and enough information to judge the quality and interpret the information produced in the analytical laboratory.

Comprehensive Water Quality and Purification, Four Volume Set provides a rich source of methods for analyzing water to assure its safety from natural and deliberate contaminants, including those that are added because of carelessness of human endeavors. Human development has great impact on water quality, and new contaminants are emerging every day. The issues of sampling for water analysis, regulatory considerations, and forensics in water quality and purity investigations are covered in detail. Microbial as well as chemical contaminations from inorganic compounds, radionuclides, volatile and semivolatile compounds, disinfectants, herbicides, and pharmaceuticals, including endocrine disruptors, are treated extensively. Researchers must be aware of all sources of contamination and know how to prescribe techniques for removing them from our water supply. Unlike other works published to date that concentrate on issues of water supply, water resource management, hydrology, and water use by industry, this work is more tightly focused on the monitoring and improvement of the quality of existing water supplies and the recovery of wastewater via new and standard separation techniques Using analytical chemistry methods, offers remediation advice on pollutants and contaminants in addition to providing the critical identification perspective The players in the global boom of water purification are numerous and varied. Having worked extensively in academia and industry, the Editor-in-Chief has been careful about constructing a work for a shared audience and cause

Part - I 'Introduction' provides a detailed introduction on analysis of water along with parameters to be determined for each industrial use, thus helps to reduce the time required for analysis and labor involved in analysis. In Part - II 'Chemical Analysis', elaborate testing procedures for all the parameters necessary for industrial uses are given. Exclusive chapters in the beginning on 'Sampling of water' and 'Sampling of Boiler water' will provide the analyst a detailed sampling program and the important sampling points so that the analysis would be more meaningful and more useful. Detailed analytical procedure for 65 chemical parameters are given which makes this book a handy reference for carrying out analysis without any difficulty. Part - III 'Microbiological Analysis' deals with the identification and determination of the density of microbial organisms that are likely to interfere in industrial processes. To aid the analyst, separate chapters starting from the Requirement of Chemicals, Glassware and Equipment, Technics involved in Microbiological Analysis, Sampling of Water for Microbiological Examination and Preparation of Media and Reagents, to identification of specific organisms are provided with a detailed discussion. In Part - IV 'Microscopical Examination', a brief account of microscopical organisms is given. The common organisms present in water along with their habitat and significance are also dealt. This book would serve as a handy reference to all wet processing industries. This book would be helpful in multifarious ways to Analysts, Chemists, Engineers, and Managers of industries and Water Treatment Consultants, Firms engaged in Water Treatment and other personnel engaged in water analysis and water treatment. This apart, this book would also be a source book to students of Industrial Engineering, Chemical Engineering, Industrial Chemistry, Applied chemistry, Environmental Engineering and Environmental Science and other allied faculties of Colleges and Universities.
