This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Drinking water contaminants exist in many different forms and come from a variety of different natural or anthropogenic sources. Some of these drinking water contaminants can be harmful to human life due to their toxic nature. Due to their harmful nature many of these contaminants are regulated by the United States Environmental Protection Agency. Two types of these regulated contaminants include hexavalent chromium and disinfection by-products. With growing concerns about hexavalent chromium contaminating drinking water supplies a comprehensive study of hexavalent chromium sources were evaluated to determine if alternative sources of hexavalent chromium are contributing to drinking water contamination. The study evaluted the possibility that hexavalent chromium could be added unintentionally to drinking water via sodium hypochlorite solutions used to disinfect drinking water. The stability as well as the oxidation states of chromium was also explored. In addition, a new method for detecting trihalomethanes and haloacetic acids was achieved. This method allows for the detection of both classes of compounds in one chromatographic analysis at the ug L-1 level by the use of gas chromatography with electron capture detection and dimethyl sulfate chemistry. As an alternative to measuring trihalomethane concentrations in drinking water many water treatment plants rely on the use of empirical models. In an effort to improve the way in which these models are used by water treatment plants, a new way of calibrating these empirical models was created. These models were calibrated using the Trihalomethane Rapid Response unit and used to predict trihalomethane concentration over a year later within 2 ug L-1 of measured concentrations.

Available in PDF, EPUB and Kindle. Book excerpt: Drinking water quality has been a matter of concern for several decades. Disinfection of drinking water improves its microbiological quality and prevents disease outbreaks. However, continuously increasing scientific research concerns the presence of organic and inorganic contaminants in water. Many of these compounds, named haloforms, originate from the procedure of disinfection, being formed during reactions of disinfectants with natural organic matter present in water. Haloforms may possess carcinogenic or mutagenic properties; therefore minimization of their concentrations in drinking water is a critical issue. Regulatory measures are becoming more and more stringent, as new health effects become known and optimized high-sensitivity analytical methodologies are being developed. Up-to-date research findings concerning all these aspects have been collected, critically reviewed, summarized, and are presented and discussed in the present book.

Available in PDF, EPUB and Kindle. Book excerpt: Drinking water disinfection has markedly reduced diseases causes by waterborne pathogenic microorganisms. However, an unintended consequence of disinfection and/or oxidation processes is the generation of disinfection byproducts (DBPs) which are formed from the reactions of disinfectants/oxidants with water matrix components. This volume of the Comprehensive Analytical Chemistry Handbook presents recent advances about the formation, identification, and quantification of inorganic and organic DBPs during oxidative processes. The book begins with a first chapter reviewing the most recent non-targeted screening approaches and workflows to characterize DBPs using low-, high-, and ultra-high-resolution mass spectrometry. The second chapter discusses the analysis of inorganic chloramines in waters using on-site and/or in-lab analytical methods. The third chapter provides an overview of the current knowledge about the mechanisms of chlorine dioxide reactions and byproducts formation. The fourth chapter presents some fundamental and practical aspects about ozonation processes in water treatment and provides an overview about ozone reaction mechanisms and byproducts formation. The fifth chapter focuses on the reactivity of halide ions, particularly bromide and iodide, with common oxidants and the role they play in determining the speciation of DBPs in treated waters. The chapter also presents strategies to mitigate the formation of DBPs during oxidation processes. Finally, the last chapter tackles the topic of DBPs formation during potable water reuse. It discusses the formation of DBPs of major concern in both memebrane-based and non-membrane-based potable water reuse treatment schemes.Researchers, water treatment specialists, and regulators will find in this book a valuable and compact resource on several key topics regarding the formation, identification, quantification, and mitigation of DBPs. - Identification and quantification of known and unknown DBPs - Formation of DBPs during different disinfection/oxidation processes - DBPs of concern in new technologies and/or new applications of existing technologies in water treatment
