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.

Kentucky's rich archaeological heritage spans thousands of years, and the Commonwealth remains fertile ground for study of the people who inhabited the midcontinent before, during, and after European settlement. This long-awaited volume brings together the most recent research on Kentucky's prehistory and early history, presenting both an accurate descriptive and an authoritative interpretation of Kentucky's past. The book is arranged chronologically—from the Ice Age to modern times, when issues of preservation and conservation have overtaken questions of identification and classification. For each time slice of Kentucky's past, the contributors describe typical communities and settlement patterns, major changes from previous cultural periods, the nature of the economy and subsistence, artifacts, the general health and characteristics of the people, and regional cultural differences. Sites discussed include the Green River shell mounds, the Central Kentucky Adena mounds and enclosures, Eastern Kentucky rockshelters, the important Wickliffe site at the confluence of the Mississippi and Ohio rivers, Fort Ancient culture villages, and the fortified towns of the Mississippian period in Western Kentucky. The authors draw from a wealth of unpublished material and offer the detailed insights and perspectives of specialists who have focused much of their professional careers on the scientific investigation of Kentucky's prehistory. The book's many graphic elements—maps, artifact drawings, photographs, and village plans—combined with a straightforward and readable text, provide a format that will appeal to the general reader as well as to students and specialists in other fields who wish to learn more about Kentucky's archaeology.
