Book Description
Chittaranjan Ray, Ph. D. , P. E. University of Hawaii at Mãnoa Honolulu, Hawaii, United States Jürgen Schubert, M. Sc. Stadtwerke Düsseldorf AG Düsseldorf, Germany Ronald B. Linsky National Water Research Institute Fountain Valley, California, United States Gina Melin National Water Research Institute Fountain Valley, California, United States 1. What is Riverbank Filtration? The purpose ofthis book is to show that riverbank filtration (RBF) isa low-cost and efficient alternative water treatment for drinking-water applications. There are two immediate benefits to the increased use of RBF: Minimized need for adding chemicals like disinfectants and coagulants to surface water to control pathogens. Decreased costs to the community without increased risk to human health. Butwhat,exactly, isRBF? In humid regions, river water naturally percolates through the ground into aquifers (which are layers of sand and gravel that contain water underground) during high-flow conditions. In arid regions, most rivers lose flow, and the percolating water passes through soil and aquifer material until it reaches the water table. During these percolation processes, potential contaminants present in river water are filtered and attenuated. If there are no other contaminants present in the aquifer or ifthe respective contaminants are present at lower concentrations, the quality of water in the aquifer can be ofhigher quality than that found in theriver. In RBF, production wells — which are placed near the banks ofrivers —pump large quantities ofwater.

Book Description
Recently, World War II veterans have come forward to claim compensation for health effects they say were caused by their participation in chemical warfare experiments. In response, the Veterans Administration asked the Institute of Medicine to study the issue. Based on a literature review and personal testimony from more than 250 affected veterans, this new volume discusses in detail the development and chemistry of mustard agents and Lewisite followed by interesting and informative discussions about these substances and their possible connection to a range of health problems, from cancer to reproductive disorders. The volume also offers an often chilling historical examination of the use of volunteers in chemical warfare experiments by the U.S. militaryâ€"what the then-young soldiers were told prior to the experiments, how they were "encouraged" to remain in the program, and how they were treated afterward. This comprehensive and controversial book will be of importance to policymakers and legislators, military and civilian planners, officials at the Department of Veterans Affairs, military historians, and researchers.
