DOWNLOAD EBOOKLiving With Mother Nature—and Other Things Learned in the Wild “Having this book in your backpack just may save your life one day.” —Jesse Weiland, national park ranger #1 New Release in Earth Sciences, Natural Disasters Prepare for all the worst case scenarios mother earth throws at you with Mother Nature is Not Trying to Kill You—the only survival kit you need to overcome wildlife, natural disasters, and everything else outdoors. Survive the unexpected. Statistically, you’re more likely to die from a vending machine than a shark. But, Rob Nelson knows many shark survivors. His college girlfriend was attacked by a crocodile and his roommate, a grizzly bear. His wife was sucked by a wave down a blowhole, he was left stranded at sea after a storm sank his sailboat, and the list goes on and on. To Rob, these “improbable” altercations are “random acts of nature,” and he’s learned how to survive them. On knots, poisonous plants, and natural disasters. Featuring 52 challenges you can encounter in the wilderness, this survival guide is your year-long crash course for ultimate disaster management. Whether you’re preparing for a moose attack or a nuclear fallout, Mother Nature is Not Trying to Kill You enables you to confront the natural world with skill and confidence. This wilderness survival guidebook also includes: • Pop culture examples like Jaws and The Revenant • Nature and science-packed stories and narratives • Diagrams, survival tips, and more! If you enjoyed books like Bushcraft 101, The Worst Case Scenario, or SAS Survival Handbook, then Mother Nature is Not Trying to Kill You is your next read!

DOWNLOAD EBOOKLegionnaires' 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 EBOOKIn the quest to reduce costs and improve the efficiency of water and wastewater services, many communities in the United States are exploring the potential advantages of privatization of those services. Unlike other utility services, local governments have generally assumed responsibility for providing water services. Privatization of such services can include the outright sale of system assets, or various forms of public-private partnershipsâ€"from the simple provision of supplies and services, to private design construction and operation of treatment plants and distribution systems. Many factors are contributing to the growing interest in the privatization of water services. Higher operating costs, more stringent federal water quality and waste effluent standards, greater customer demands for quality and reliability, and an aging water delivery and wastewater collection and treatment infrastructure are all challenging municipalities that may be short of funds or technical capabilities. For municipalities with limited capacities to meet these challenges, privatization can be a viable alternative. Privatization of Water Services evaluates the fiscal and policy implications of privatization, scenarios in which privatization works best, and the efficiencies that may be gained by contracting with private water utilities.

DOWNLOAD EBOOKWith the narrative punch of Jonathan Harr’s A Civil Action and the commitment to environmental truth-telling of Erin Brockovich, The Fluoride Deception documents a powerful connection between big corporations, the U.S. military, and the historic reassurances of fluoride safety provided by the nation’s public health establishment. The Fluoride Deception reads like a thriller, but one supported by two hundred pages of source notes, years of investigative reporting, scores of scientist interviews, and archival research in places such as the newly opened files of the Manhattan Project and the Atomic Energy Commission. The book is nothing less than an exhumation of one of the great secret narratives of the industrial era: how a grim workplace poison and the most damaging environmental pollutant of the cold war was added to our drinking water and toothpaste.

DOWNLOAD EBOOKRural Water Systems for Multiple Uses and Livelihood Security covers the technological, institutional, and policy choices for building rural water supply systems that are sustainable from physical, economic, and ecological points-of-view in developing countries. While there is abundant theoretical discourse on designing village water supply schemes as multiple use systems, there is too little understanding of the type of water needs in rural households, how they vary across socio-economic and climatic settings, the extent to which these needs are met by the existing single use water supply schemes, and what mechanisms exist to take care of unmet demands. The case studies presented in the book from different agro ecological regions quantify these benefits under different agro ecological settings, also examining the economic and environmental trade-offs in maximizing benefits. This book demonstrates how various physical and socio-economic processes alter the hydrology of tanks in rural settings, thereby affecting their performance, also including quantitative criteria that can be used to select tanks suitable for rehabilitation. - Covers interdisciplinary topics deftly interwoven in the rural context of varying geo-climatic and socioeconomic situations of people in developing areas - Presents methodologies for quantifying the multiple water use benefits from wetlands and case studies from different agro ecologies using these methodologies to help frame appropriate policies - Provides analysis of the climatic and socioeconomic factors responsible for changes in hydrology of multiple use wetlands in order to help target multiple use water bodies for rehabilitation - Includes implementable models for converting single use water supply systems into multiple use systems
