Book Description
The objective of this project is to understand the potential mechanisms of antimicrobial resistance of E. coli and opportunistic pathogens under disinfection conditions. The project involves molecular techniques to understand genetic changes in biofilm and suspended bacteria in response to different disinfectant conditions. It examines the effects of using single chemical disinfectants (free chlorine, chloramines, and chlorine dioxide) compared with UV light pretreatment, as well as the impact of pipe material (polycarbonate or cast iron) and E. coli mutations. Field studies include both surface water and groundwater.

Book Description
Poland, like other post-communist countries, is undergoing a transformation into a capitalist system. This transformation affects the country in many ways: economic, social, psychological and also ecological. Ecological problems are strongly connected with the political, economic and psychological inheritance of the past, as well as with changes in the post-communist society. In order to understand these problems, it is necessary to consider the following issues: - the geographic situation of Poland - the political transformations that occurred after World War II – forced development of heavy industry combined with neglect of its effects on the environment, and - the economic problems The three main goals of Environmental Engineering V are (I) to assess the state of scientific research in various areas of environmental engineering. (II) to evaluate organizational, technical and technological progress in contributing to ecological security, and (III) to determine the place of environmental engineering in sustainable development, taking into account political and economic conditions. Environmental Engineering V is of interest for academics, engineers and professionals involved in environmental engineering, seeking solutions for environmental problems in emerging new democracies, especially those who plan to participate in numerous projects sponsored by the European Union.

Book Description
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.

Book Description
Maintaining the microbial quality in distribution systems and connected installations remains a challenge for the water supply companies all over the world, despite many years of research. This book identifies the main concerns and knowledge gaps related to regrowth and stimulates cooperation in future research. Microbial Growth in Drinking Water Supplies provides an overview of the regrowth issue in different countries and the water quality problems related to regrowth. The book assesses the causes of regrowth in drinking water and the prevention of regrowth by water treatment and distribution.

Book Description
Recent Trends in Biofilm Science and Technology helps researchers working on fundamental aspects of biofilm formation and control conduct biofilm studies and interpret results. The book provides a remarkable amount of knowledge on the processes that regulate biofilm formation, the methods used, monitoring characterization and mathematical modeling, the problems/advantages caused by their presence in the food industry, environment and medical fields, and the current and emergent strategies for their control. Research on biofilms has progressed rapidly in the last decade due to the fact that biofilms have required the development of new analytical tools and new collaborations between biologists, engineers and mathematicians. - Presents an overview of the process of biofilm formation and its implications - Provides a clearer understanding of the role of biofilms in infections - Creates a foundation for further research on novel control strategies - Updates readers on the remarkable amount of knowledge on the processes that regulate biofilm formation
