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.

Carbon Pollution Emission Guidelines for Existing Stationary Sources - Electric Utility Generating Units (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Carbon Pollution Emission Guidelines for Existing Stationary Sources - Electric Utility Generating Units (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 In this action, the Environmental Protection Agency (EPA) is establishing final emission guidelines for states to follow in developing plans to reduce greenhouse gas (GHG) emissions from existing fossil fuel-fired electric generating units (EGUs). Specifically, the EPA is establishing: Carbon dioxide (CO 2) emission performance rates representing the best system of emission reduction (BSER) for two subcategories of existing fossil fuel-fired EGUs-fossil fuel-fired electric utility steam generating units and stationary combustion turbines; state-specific CO 2 goals reflecting the CO 2 emission performance rates; and guidelines for the development, submittal and implementation of state plans that establish emission standards or other measures to implement the CO 2 emission performance rates, which may be accomplished by meeting the state goals. This final rule will continue progress already underway in the U.S. to reduce CO 2 emissions from the utility power sector. This book contains: - The complete text of the Carbon Pollution Emission Guidelines for Existing Stationary Sources - Electric Utility Generating Units (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) - A table of contents with the page number of each section
