Economic Analysis of the Implementation of Permeable Reactive Barriers for Remediation of Contaminated Ground Water
This report presents an analysis of the cost of using permeable reactive barriers to remediate contaminated ground water. When possible, these costs are compared with the cost of pump-and-treat technology for similar situations. Permeable reactive barriers are no longer perceived as an innovative remediation technology but are rapidly maturing and may be considered as a standard remediation technology, similar to pump-and-treat. PRB cost information was obtained from a variety of sources, including reports, surveys, and interviews. Costs were broken out into four general categories: site characterization, design, construction, and operation and maintenance. Subcategories within these four further detailed the costs.
Resting Places
In its third edition, this massive reference work lists the final resting places of more than 14,000 people from a wide range of fields, including politics, the military, the arts, crime, sports and popular culture. Many entries are new to this edition. Each listing provides birth and death dates, a brief summary of the subject's claim to fame and their burial site location or as much as is known. Grave location within a cemetery is provided in many cases, as well as places of cremation and sites where ashes were scattered. Source information is provided.
National Register of Historic Places, 1966-1994
Lists buildings, structures, sites, objects, and districts that possess historical significance as defined by the National Register Criteria for Evaluation, in every state.
Site Formation Processes of Submerged Shipwrecks
Many factors influence the formation of shipwreck sites: the materials from which the ship was built, the underwater environment, and subsequent events such as human activity, storms, and chemical reactions. In this first volume to comprehensively catalogue the physical and cultural processes affecting submerged ships, Matthew Keith brings together experts in diverse fields such as geology, soil and wood chemistry, micro- and marine biology, and sediment dynamics. The case studies identify and examine the natural and anthropogenic processes--corrosion and degradation on one hand, fishing and trawling on the other--that contribute to the present condition of shipwreck sites. The contributors also discuss how these varied and often overlapping events influence the archaeological record. Offering an in-depth analysis of emerging technologies and methods—acoustic positioning, computer modeling, and site reconstruction--this is an essential study for the research and preservation of submerged heritage sites.
The Site
Poetry or potsherds? That’s the surprising dilemma one of Canada’s well-known nature writers confronts in The Site: A Personal Odyssey, a highly personalized account of a lifetime’s involvement as an avocational archaeologist. With deft descriptive powers, Robert Nero leads us gently into this new facet of his amazing spectrum of interests. Not unexpectedly, there even is poetry in his approach to studying prehistoric remains! From childhood through adolescence, to wartime service with the U.S. Army in the Southwest Pacific, from exploring the vast sand dunes of Lake Athabasca to excavating a 3,000-year-old site he discovered west of Winnipeg, Nero allows us to share his enthusiasm and excitement in outdoor adventures. There is always a wonderful immediacy in his narrative, the mark of a gifted writer, whether expressed in prose or poetry.
Calculating Risks?
"By matching agency decision data to detailed census information using geographic information systems (GIS) technology, the authors show that most hazardous waste sites do not pose sufficient risk to merit the most stringent cleanup options. Those sites that do pose considerable risk to exposed populations often receive inadequate attention, because government decisions to target cleanups are based more on political factors than on actual risks. The authors propose policy reforms that could significantly reduce cleanup costs without sacrificing the protection of human health."--BOOK JACKET.
