This manual is a source document for utilities that are considering a coagulant changeover. It is intended to provide an appreciation of what must be considered for a successful changeover based on the input of U.S. and Canadian utilities (Chapters 1 and 6). New regulatory requirements will likely have the broadest and most substantial impact on primary coagulant use (Chapter 3). The Interim Enhanced Surface Water Treatment Rule (IESWTR) and Stage 1 Disinfectant and Disinfection Byproducts Rule (Stage 1 DBPR) will make finished water requirements more stringent to address microbial removal and the impacts of disinfection. Enhanced Coagulation and/or other operational and treatment practices will be used to achieve these requirements. The science of coagulation (Chapter 4) requires a special focus to address the intricacies of coagulation chemistry. The manual provides a step-by-step methodology to conduct a coagulant changeover using a detailed protocol (Chapter 5) -- background, executive summary.

Issued to highlight information appropriate to small systems, to provide a background on regulations, and to present a summary of related research with an emphasis on filtration and disinfection technologies. Also includes information on how the systems can be "packaged" with remote monitoring and control technologies to provide a healthy and affordable solution for the small systems.

Disinfection Byproducts in Drinking Water: Detection and Treatment presents cutting-edge research on how to understand the procedures, processes and considerations for detecting and treating disinfection by-products from drinking water, swimming pool water, and wastewater. The book begins with an overview of the different groups of Disinfection Byproducts (DBPs), such as: Trihalomethanes (THM), Halo acetic acids, and Haloacetonitrile (HAN). This coverage is quickly followed by a clear and rigorous exposition of the latest methods and technologies for the characterization, occurrence, formation, transformation and removal of DBPs in drinking water. Other chapters focus on ultraviolet-visible spectroscopy, electron spin resonance, and gas chromatography-mass spectrometry. Researchers will find a valuable resource to a breath of topics for DBP detection and treatment, including various recent techniques, such as microfiltration, nanofiltration membrane and nanotechnology. - Explains the latest research in detection, treatment processes and remediation technologies - Includes sampling, analytical and characterization methods and approaches - Covers cutting-edge research, including membrane based technologies, nanotechnology treatment technologies and bioremediation treatment technologies - Provides background information regarding contamination sources

This book serves as a technical yet practical risk management manual for professionals working with water and wastewater organizations. It provides readers with a functional comprehension of water and wastewater operations as well as a broad understanding of industry derivations and various stakeholder interconnectivity. This knowledge is imperative, as most administrative professionals are proficient in their respective areas of expertise but sometimes lack fluency on the broader technical aspects of their organization’s purpose, operations, and externalities. It also examines risk management best practices and provides an actionable review of doing the right thing, the right way, every time through a combination of core risk management principles. These include enterprise, strategic, operational, and reputational risk management, as well as risk assessments, risk/frequency matrixes, checklists, rules, and decision-making processes. Finally, the book addresses the importance of risk transfer through insurance policies and provides best practices for the prudent selection of these policies across different scenarios. Features: Provides an understanding of water and wastewater technical operations to properly implement sound risk management and insurance programs. Emphasizes the importance of building well-designed, resilient systems, such as policies, processes, procedures, protocol, rules, and checklists that are up to date and fully implemented across a business. Offers a detailed look into insurance policy terms and conditions and includes practical checklists to assist readers in structuring and negotiating their own policies. Handbook of Risk and Insurance Strategies for Certified Public Risk Officers and Other Water Professionals combines practical knowledge of technical water/wastewater operations along with the core subjects of risk management and insurance for practicing and aspiring professionals charged with handling these vital tasks for their organizations. Readers will also gain invaluable perspective and knowledge on best-in-class risk management and insurance practices in the water and wastewater industries.
