Book Description
Prepared by the Task Committee on Land Application of Sludge of the Committee on Water Pollution Management of the Environmental Engineering Division of ASCE. This report presents research on the land application of wastewater sludge, especially quantitative and qualitative aspects of soil-sludge interaction. Each year, approximately 6.2 million dry metric tons of wastewater sludge are produced by municipal wastewater treatment facilities in the United States. The annual sludge production is expected to reach 12 million dry metric tons by the year 2000. Sludge use and disposal options include incineration, ocean disposal, marketing of processed sludge, landfilling, and land application. Land application of sludge is achieved by spreading the sludge over the ground surface or incorporating it within the topsoil by injection, disking, or plowing. Sludge is applied to agricultural and forest lands for its nutrient value and to disturbed areas for soil amendment and reclamation purposes. At present, land application is the logical alternative because of its environmental and economic advantages over the other methods. Topics include: mechanisms for the removal of nitrogen and phosphorus, the role of trace elements, hydrologic effects of soil-sludge interaction, use of municipal sludge to reclaim mined land, and health effects. The report concludes with recommendations for future research.

Book Description
Calling for ecologically and economically sound wastewater treatment systems, the authors of Natural Wastewater Treatment Systems explore the use of wetlands, sprinkler or deep irrigation, groundwater recharge, and other natural systems as sustainable methods for the treatment and management of wastewater. Based on work by prominent experts in natu

Book Description
Soil degradation is clearly one of the most pressing problems facing man kind. A continuation of soil degradation will eventually lead to a loss in crop productivity even though fertilizers and other inputs often result in increased yields in the short term. Soil degradation also leads to environ mental pollution. A decrease in soil quality invariably leads to a decrease in water quality, and often in air quality. While there is a clear consensus that soil degradation is a major problem, the literature on this subject leaves numerous baffling questions. If statis tics on land degradation are correct, there is a definite cause for concern, and present a mammoth challenge for agricultural scientists. There are those that say the scientific community has over dramatized this issue, and created a credibility problem. Consequently; Volume 11 of Advances in Soil Science was organized by Dr. Rattan Lal who is recognized as a lead ing authority on the subject. The objective of Volume 11 was to assess the types and processes of soil degradation and establish some of the major cause-effect relationships. Volume II documented the seriousness of soil degradation in many parts of the world. Therefore, it seemed immediately important to devote a volume to the principles and technologies for restor ing degraded soils to a productive status. While the land resources are limited, world population is rapidly increasing, particularly in developing countries. Dr.

Book Description
The border region lies 100 kilometers/60 miles on each side of the U.S.-Mexican border and encompasses parts of four states in the United States and the six Mexican states of Baja California. Approximately 12 million people live in the U.S. counties and Mexican municipalities on the border. The high density of people and increased industrialization since the passage of NAFTA has placed an even greater burden on the inadequate infrastructure and environnmental resources of the region. Exacerbating the problem is the fact that many U.S. counties along the border are categorized as "economically distressed." and few communities possess the resources needed to address environmental concerns. This volume examines many of the environmental issues that pertain to this rapid urbanization in this region.
