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.

America is in the midst of a bloody civil war. Donald Trump has won re-election in what the majority of Americans are considering a scandal. Political, religious, gender, and racial animosities are inflamed. Full scaled rioting, that has claimed the lives of thousands, rages across the land. In New California, America's recently constituted 51st state, rookie reporter Frank Lee falls in love with Yvonne, the young leader of a militant leftist group. He discovers that she may have ties to the corrupt Francis Kintuket, warden of New California's Prachard Colony. Frank Lee has been tasked with interviewing Warden Kintuket, who has organized and will supervise a series of state sponsored capital punishment verdicts, all of them one after the other. But there is a twist that Frank encounters, and his survival and the fate of the nation depends on his navigating his way through the calamity of Warden Kintuket's warped mind.
