Download or read book Management of Legionella in Water Systems written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2020-02-20 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Application of Heat and Chemicals in the Control of Biofouling Events in Wells written by George Alford and published by CRC Press. This book was released on 1998-12-29 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Application of heat and chemicals to a biofouling well is a relatively new approach for water well rehabilitation. For the first time, The Application of Heat and Chemicals in the Control of Biofouling Events in Wells explains what many microbiologists now believe is the most effective form of treatment: pasteurization and application of chemicals. Consider an increasingly prevalent alternative to traditional forms of encrustation: an approach which recognizes that water wells are conduits to the sub-surface realm, whose organisms impact the production characteristics of wells.

Download or read book Best Practice Guide on the Control of Iron and Manganese in Water Supply written by Adam Postawa and published by IWA Publishing. This book was released on 2013-08-14 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Best Practice Guide on the Control of Iron and Manganese in Water Supply is one of a series produced by the International Water Association’s Specialist Group on Metals and Related Substances in Drinking Water. Iron and manganese are often found in soft upland water sources associated with natural organic matter and are also commonly found in the groundwater abstracted from confined and unconfined aquifers. The presence of iron and manganese in water is one of the most frequent reasons for customers’ complaint due to aesthetic issues (yellow, brown and black or stains on laundry and plumbing fixtures). These two metals can be removed fairly readily by physico-chemical treatment. The municipal treatment systems deployed derive benefit from their larger scale, particularly in relation to control, but the processes used are less suitable for the numerous small supplies that are the most common water supplies throughout Europe, especially in rural areas. One important source of iron in drinking water is from old corroded cast-iron water mains, historically the material used most commonly in supply networks. Replacement and refurbishment is very expensive and the major challenge is how best to prioritize available expenditure. The purpose for this Best Practice Guide on the Control of Iron and Manganese in Water Supply is to give readers the broad view of a problem based on state-of-the-art compilation of the range of scientific, engineering, regulatory and operational issues concerned with the control of iron and manganese in drinking water. The Guide is of interest to water utility practitioners, health agencies and policy makers, as well as students on civil engineering and environmental engineering courses. Authors: Dr Adam Postawa, AGH University of Science and Technology, Faculty of Geology, Geophysics and Environment Protection, Krakow, Poland and Dr Colin R Hayes, University of Swansea, UK, Chair of IWA Specialist Group on Metals and Related Substances in Drinking Water.

Download or read book Investigation of Relief Wells Mississippi River Levees Alton to Gale Illinois written by Raymond Lawree Montgomery and published by . This book was released on 1972 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pumping tests, chemical and biological analyses of water samples, and well screen inspection by means of a borehole TV camera were conducted in 1969 as part of a study of the efficiency of the relief well system along the Mississippi River between Alton and Gale, Illinois. The purposes of this study are to determine the extent and causes of well deterioration and to investigate methods for improving and maintaining the efficiency of the well system. The relief wells were designed by personnel of the U.S. Army Engineer Waterways Experiment Station and built under the supervision of the U.S. Army Engineering District, St. Louis (SLD). The wells included in this investigation were installed between 1953 and 1955. Since then, SLD has performed a series of well pumping tests, periodically inspected the relief well system, and observed the operation of the wells during high river stages of the Mississippi River.

Download or read book Providing Safe Drinking Water in Small Systems written by Joseph Cotruvo and published by Routledge. This book was released on 2019-01-15 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continued lack of access to adequate amounts of safe drinking water is one of the primary causes of infant morbidity and mortality worldwide and a serious situation which governments, international agencies and private organizations are striving to alleviate. Barriers to providing safe drinking water for rural areas and small communities that must be overcome include the financing and stability of small systems, their operation, and appropriate, cost-effective technologies to treat and deliver water to consumers. While we know how to technically produce safe drinking water, we are not always able to achieve sustainable safe water supplies for small systems in developed and developing countries. Everyone wants to move rapidly to reach the goal of universal safe drinking water, because safe water is the most fundamental essential element for personal and social health and welfare. Without safe water and a safe environment, sustained personal economic and cultural development is impossible. Often small rural systems are the last in the opportunity line. Safe Drinking Water in Small Systems describes feasible technologies, operating procedures, management, and financing opportunities to alleviate problems faced by small water systems in both developed and developing countries. In addition to widely used traditional technologies this reference presents emerging technologies and non-traditional approaches to water treatment, management, sources of energy, and the delivery of safe water.
