This manual suggests design operating and performance criteria for specific surface water quality conditions to provide the optimum protection from microbiological contaminants.
Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.
The EPA has established regulations which classify four types of disinfection byproducts - TTHMs, haloacetic acids, bromate, and chlorite - and requires public water systems limit these byproducts to specific levels. Most of the information required to comply with these standards is either scattered throughout the literature or derived from confere
The third edition of A Guide to Hygiene and Sanitation in Aviation addresses water, food, waste disposal, cleaning and disinfection, vector control and cargo safety, with the ultimate goal of assisting all types of airport and aircraft operators and all other responsible bodies in achieving high standards of hygiene and sanitation, to protect travellers and crews engaged in air transport. Each topic is addressed individually, with guidelines that provide procedures and quality specifications that are to be achieved. The guidelines apply to domestic and international air travel for all developed and developing countries.
This fourth edition of the anthrax guidelines encompasses a systematic review of the extensive new scientific literature and relevant publications up to end 2007 including all the new information that emerged in the 3-4 years after the anthrax letter events. This updated edition provides information on the disease and its importance, its etiology and ecology, and offers guidance on the detection, diagnostic, epidemiology, disinfection and decontamination, treatment and prophylaxis procedures, as well as control and surveillance processes for anthrax in humans and animals. With two rounds of a rigorous peer-review process, it is a relevant source of information for the management of anthrax in humans and animals.
This volume offers extensive information on preventive and infection surveillance procedures, routines and policies adapted to the optimal infection control level needed to tackle today’s microbes in hospital practice. It especially focuses on preventive measures for serious hospital infections. Each chapter includes a practical section that addresses the main aspects of procedures and treatment, and a theoretical section that contains updated documentation that can be used for further study, or to help select infection control measures. Infection control concerns all healthcare professional working directly or indirectly with patients; in diagnosis, treatment, isolation measures, operations, equipment, drugs, cleaning, textiles, transport, porter service, food and water, building and maintenance, etc. Hygiene and environmental control is central to infection prevention for patients, visitors and staff alike. Good hygienic practices, individual infection control, well implemented and frequent environmental cleaning, and a high professional standard of hygiene in the treatment and care of patients, are essential to patient safety and a safe working environment. Addressing this essential topic, this book is intended for doctors, nurses and other healthcare workers, students in health-related subjects, hospital managers and health bureaucrats, as well as patients and their families.
New edition covers the latest practices, regulations, and alternative disinfectants Since the publication of the Fourth Edition of White's Handbook of Chlorination and Alternative Disinfectants more than ten years ago, the water industry has made substantial advances in their understanding and application of chlorine, hypochlorite, and alternative disinfectants for water and wastewater treatment. This Fifth Edition, with its extensive updates and revisions, reflects the current state of the science as well as the latest practices. Balancing theory with practice, the Fifth Edition covers such important topics as: Advances in the use of UV and ozone as disinfectants Alternative disinfectants such as chlorine dioxide, iodine, and bromine-related products Advanced oxidation processes for drinking water and wastewater treatment New developments and information for the production and handling of chlorine Latest regulations governing the use of different disinfectants For each disinfectant, the book explains its chemistry, effectiveness, dosing, equipment, and system design requirements. Moreover, the advantages and disadvantages of each disinfectant are clearly set forth. References at the end of each chapter guide readers to the primary literature for further investigation. Authored and reviewed by leading experts in the field of water and wastewater treatment, this Fifth Edition remains an ideal reference for utilities, regulators, engineers, and plant operators who need current information on the disinfection of potable water, wastewater, industrial water, and swimming pools.
