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
The Civilian Conservation Corps (CCC), Franklin D. Roosevelt¿s New Deal program to help young, unemployed men during the Great Depression by hiring them to work in a mammoth ¿forest army,¿ completed thousands of vital conservation projects nationwide. They were paid just $30 a month¿a dollar a day. In the Catskills, at CCC camps in Ulster County, Greene County, Schoharie County, Delaware County, and Broome County, city boys and their country cousins, under the tutelage of local woodsmen and mechanics, wielded axes, mattocks and shovels to transform the Catskills in subtle and significant ways, planting millions of trees (more than 3 1⁄2 million in Delaware County in 1934 alone), fighting stream and soil erosion, and building roads, fire towers, hiking trails, ski trails, and the campsites at North Lake, Woodland Valley, Devil¿s Tombstone and Beaverkill. This new history, illustrated with more than 100 photographs and maps, tells their story--who they were, where they came from, what they did, and the legacy they left behind.
