Selected papers from the Second National Low Impact Development Conference, held in Wilmington, North Carolina, March 12-14, 2007.

Low impact development (LID) began as an environmentally friendly method to conserve natural water sources, manage stormwater runoff, and preserve water quality. Today, LID encompasses methods of construction and engineering that preserve the ecosystem as a whole. This report contains 32 selected papers that specifically highlight new and continuing low impact practices, including research, recent developments, and community adoption and acceptance....

Prepared by the Task Committee on Contaminated Ground Water Modeling of the Committee on Ground Water Quality of the Environmental Engineering Division of ASCE.

Quality of Ground Water assesses widely used models of contaminated ground water. Based on a survey of the professional community to determine which models are in frequent use, the models were classified according to a unified set of criteria. The Manual presents guidelines for the application of the models that include the capabilities and limitations of each model.

Prepared by the Environmental Technology Evaluation Center (EvTEC), a service center of CERF/IIEC.

This Technology Verification report describes the nature and scope of the environmental evaluation of the performance of the Plasma Enhanced Melter(TM) (PEM(TM)) system for waste treatment. The evaluation was conducted through a cooperative program established in 1998 between the Washington State Department of Ecology, Integrated Environmental Technology Inc., Allied Technology Group, and the Civil Engineering Research Foundation. The goal of this report is to provide potential users...

Cement-based concrete has excellent properties as a construction material, and the raw materials of cement-rocks, and limestone and clay-are bountiful. Yet its production generates high quantities of CO₂, making it a potentially unsustainable material. However, there are no alternatives to concrete and steel as basic methods for development of socioeconomic infrastructure at this time. Highlighting sustainability issues in the construction industry, The Sustainable Use of Concrete presents guidelines on how to move toward sustainable concrete construction.

Natural resources management has two principal dimensions:

• Science-illuminated (earth, space, hydrological, pedological, information, etc. sciences) management of local resources (waters, soils, bioresources, minerals, rocks, sediments, etc.) in an ecologically-sustainable manner, and
• Value-addition through processing of natural products, through the application of technology is most marked in the case of some mineral products.

The wellness of a community is dependent upon the security of food, water, environment and...

A comprehensive guide to sludge management, reuse, and disposal

When wastewater is treated, reducing organic material to carbon dioxide, water, and bacterial cells--the cells are disposed of, producing a semisolid and nutrient-rich byproduct called sludge. The expansion in global population and industrial activity has turned the production of excess sludge into an international environmental challenge, with the ultimate disposal of excess sludge now one of the most expensive problems faced by wastewater facilities.

Written by two leading environmental engineers,...

This book presents the results of the latest research regarding water balance covers for containing solid waste sites. Water balance covers (also known as store-and-release, evapotranspiration, or ET covers) are an effective and efficient alternative to conventional clay liner or geosynthetic covers, especially in arid regions. By cycling water from the soil to the atmosphere during growing seasons, water balance covers minimize the percolation of rainwater through the soil and thus the production of leachate from landfill contents.

This book introduces water balance covers and...

Now ubiquitous in modern life, spatial data present great opportunities to transform many of the processes on which we base our everyday lives. However, not only do these data depend on the scale of measurement, but also handling these data (e.g., to make suitable maps) requires that we account for the scale of measurement explicitly. Scale in Spatial Information and Analysis describes the scales of measurement and scales of spatial variation that exist in the measured data. It provides you with a series of tools for handling spatial data while accounting for scale.
