Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources.The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies.The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.

Sharon Robinson, the daughter of baseball legend Jackie Robinson, has crafted a hearwarming, true story about growing up with her father. When Jackie Robinson retires from baseball and moves his family to Connecticut, the beautiful lake on their property is the center of everyone's fun. The neighborhood children join the Robinson kids for swimming and boating. But oddly, Jackie never goes near the water. In a dramatic episode that first winter, the children beg to go ice skating on the lake. Jackie says they can go--but only after he tests the ice to make sure it's safe. The children prod and push to get Jackie outside, until hesitantly, he finally goes. Like a blind man with a stick, (contd.)

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 captivating story of an ordinary bartender who's changing the world through clean water. Doc Hendley never set out to be a hero. In 2004, Hendley-a small- town bartender- launched a series of wine-tasting events to raise funds for clean-water projects and to bring awareness to the world's freshwater crisis. He planned to donate the proceeds through traditional channels, but instead found himself traveling to one of the world's most dangerous hot spots: Darfur, Sudan. There, Doc witnessed a government-sponsored genocide where the number-one weapon wasn't bullets-it was water. The Janjaweed terrorists had figured out that shooting up a bladder containing 10,000 liters of water, or dumping rotting corpses into a primary water source is remarkably efficient for the purposes of mass extermination. With limited funds, Doc realized that he couldn't build new wells costing $10,000 a pop, but he could hire local workers to restore a damaged well for a mere $50 each. He'd found his mission. Today, Doc and Wine to Water continue to help stricken peoples repair and maintain water- containment systems in places like Darfur, Cambodia, Uganda, and Haiti. Doc is a regular, rough-and-tumble guy who loves booze, music, and his Harley- but he also wanted to help. Wine to Water is a gripping story about braving tribal warfare and natural disasters and encountering fascinating characters in far-flung regions of the world. It is also an authoritative account of a global crisis and an inspirational tale that proves how ordinary people can improve the world.
