Interest in phytoremediation as a solution for contaminants in groundwater and soil has exploded. The project documented in Phytoremediation of Hydrocarbon Contaminated Soils presents innovative technology for environmental clean up using in situ treatment. It describes the results of a field study focusing on hydrocarbon contamination, especially polynuclear aromatic hydrocarbons, in surface and near surface soils.
The field demonstration used soils contaminated with aged diesel fuels. The random block design enabled the investigators to test the statistical difference in the effects of...

One of the most widely used techniques for treating soils contaminated with volatile organic compounds, soil vapor extraction (SVE) can also be applied to semi-volatile organic compounds (SVOCs) if the soil is heated, by applying electromagnetic energy in the radio frequency (FR) range, to increase the vapor pressure of the contaminants. Although R F-SVE systems used in previous field demonstrations have had varying d egrees of success, questions remain concerning its viability and cost- effectiveness. Soil Vapor Extraction Using Radio Frequency Heating: R esource Manual and Technology...

Complete and quantitative, NAPL Removal: Surfactants, Foams, and Micro emulsions, belongs to a ten-monograph series that records the results of the Department of Defense/Advanced Applied Technology Demonstration Facility environmental technology demonstrations. It presents the out come of field demonstrations of innovative in situ remediation technol ogies. In situ surfactant and cosolvent flushing for nonaqueous phase liquids constitutes a technique with the potential to reduce the mass of NAPL - a continuing source of groundwater contamination. This monog raph details two technologies -...

While innovative technologies in remediation need to be developed, so do innovative ways of site assessment. This monograph describes the development, testing, and performance of a new laser-induced fluorescence soil probe. A screening tool for site characterization, this probe has the potential to provide an economical, rapid assessment of contaminated sites.
Cone Penetrometer testing equipment advances the probe into the subsurface. The probe identifies hydrocarbon classes using a multi-channel excitation-emission matrix. This technique facilitates the collection of significant amounts...

A part of the continuing effort to provide innovative in situ remediation techniques, Remediation of Firing-Range Impact Berms presents the results of a soil washing and leaching project. The demonstration set as its primary objective providing reliable, detailed performance data to evaluate the feasibility and cost of implementing a full-scale system. Its secondary objective was to demonstrate the effectiveness of the technology in producing a 'clean' soil based on analytical results.
The project included the following steps:

Bench scale treatability studies of prospective...

Demographers predict that the world population will double during the first half of the 21st century before it will begin to level off. In this volume, a group of prominent authors examine what societal changes must occur to meet this challenge to the natural environment and the transformational changes that we must experience to achieve sustainability. Frances Cairncross, Herman E. Daly, Stephen H. Schneider and others provide a broad discussion of sustainable development. They detail economic and environmental, as well as spiritual and religious, corporate and social, scientific and...

Volume three of the Childrens Treasure Book contains The Arabian Nights. Tales include: Sinbad the Sailor, The Story of Aladdin and his Wonderful Lamp, The Story of Ali Baba and the Forty Thieves, The Enchanted House, Prince Ahmed and the Fairy Perie Banou, and Prince Camaralzaman and Princess Badoura. The book is profusely illustrated by various different illustrators including Robert Pimlott, C. H. Ward and others. Pook Press celebrates the great Golden Age of Illustration in childrens literature. Many of the earliest childrens books, particularly those dating back to the 1850s and before,...
