This new manual is an indispensable working lab guide and reference for water/wastewater quality analysis. Based on procedures from "Standard Methods" and "Methods for Chemical Analysis of Water and Waste (EPA)," and other pertinent references the Water and Wastewater Examination Manual is an excellent complement to these references-that you will want to keep at your fingertips. Written especially for use by water quality laboratory technicians and water/wastewater operators, managers and supervisors-who will use this practical manual every day. Procedures are included for parameters frequently used in water quality analysis.

'Brilliant, Fantastic and Significant' - Dr George McGavin Ants are seemingly everywhere, and this familiarity has led to some contemptuous and less than helpful stereotypes. In this compelling insight into the natural and cultural history of ants, Richard Jones helps to unravel some of the myths and misunderstanding surrounding their remarkable behaviours. Ant aggregations in large (often mind-bogglingly huge) nests are a complex mix of genetics, chemistry, geography and higher social interaction. Their forage trails – usually to aphid colonies but occasionally into the larder – are maintained by a wondrous alchemy of molecular scents and markers. Their social colony structure confused natural philosophers of old and still taxes the modern biologist today. Beginning the book with a straightforward look at ant morphology, Jones then explores the ant species found in the British Isles and parts of nearby mainland Europe, their foraging, nesting, navigating and battle instincts, how ants interact with the landscape, their evolution, and their place in our understanding of how life on earth works. Alongside this, he explores the complex relationship between humans and ants, and how ants went from being the subject of fables and moral storytelling to become popular research tools. Drawing on up-to-date science and featuring striking colour photographs throughout, this book presents a convincing case for why ants are worth our greater recognition and respect.

Microbiological tests have proven to be an indispensable part of environmental contaminant detection. It has also been tremendously difficult to find a comprehensive training manual and laboratory manual for those procedures. Microbiological Examination of Water and Wastewater now provides that much-needed resource for laboratory trainees and environmental professionals alike. An all-inclusive guide to applications and techniques of microbiological testing, Microbiological Examination of Water and Wastewater includes coverage of General Microbiology, Environmental Microbiology, Environmental Microbiology Laboratory, plus Techniques and Methods in Routine Environmental Microbiology Laboratory. By exploring the fundamentals of microbiology, as well as microbial metabolism, growth, control, and classification, trainees will better understand the purpose and manner of microbiological examination. Those details also make Microbiological Examination of Water and Wastewater ideal as a standard guidebook for laboratories, water and wastewater treatment plants, and the communities they serve.

UV-Visible Spectrophotometry of Water and Wastewater is the first book dedicated to the use of UV spectrophotometry for water and wastewater quality monitoring. Using practical examples the reader is shown how this technique can be a source of new methods of characterization and measurement. Easy and fast to run, this simple and robust analytical technique must be considered as one of the best ways to obtain a quantitative estimation of specific or aggregate parameters (eg. Nitrate, TOC), and simultaneously qualitative information on the global composition of water and its variation.* First electronic library of UV-spectra providing data readily available for researchers and users* Provides a theoretical basis for further research in the field of spectra exploitation* Contains helpful practical applications

This book presents the basic principles for evaluating water quality and treatment plant performance in a clear, innovative and didactic way, using a combined approach that involves the interpretation of monitoring data associated with (i) the basic processes that take place in water bodies and in water and wastewater treatment plants and (ii) data management and statistical calculations to allow a deep interpretation of the data. This book is problem-oriented and works from practice to theory, covering most of the information you will need, such as (a) obtaining flow data and working with the concept of loading, (b) organizing sampling programmes and measurements, (c) connecting laboratory analysis to data management, (e) using numerical and graphical methods for describing monitoring data (descriptive statistics), (f) understanding and reporting removal efficiencies, (g) recognizing symmetry and asymmetry in monitoring data (normal and log-normal distributions), (h) evaluating compliance with targets and regulatory standards for effluents and water bodies, (i) making comparisons with the monitoring data (tests of hypothesis), (j) understanding the relationship between monitoring variables (correlation and regression analysis), (k) making water and mass balances, (l) understanding the different loading rates applied to treatment units, (m) learning the principles of reaction kinetics and reactor hydraulics and (n) performing calibration and verification of models. The major concepts are illustrated by 92 fully worked-out examples, which are supported by 75 freely-downloadable Excel spreadsheets. Each chapter concludes with a checklist for your report. If you are a student, researcher or practitioner planning to use or already using treatment plant and water quality monitoring data, then this book is for you! 75 Excel spreadsheets are available to download.
