CONTAMINATION OF GROUNDWATER BY TRICHLOROETHYLENE AND OTHER VOLATILE HALOGENATED SOLVENTS REPRESENTS A SERIOUS THREAT TO THE NATION'S DRINKING WATER. CURRENT TREATMENT TECHNIQUES FOR CONTROLLING SUCH CONTAMINATION ARE LIMITED TO AERATION, ADSORPTION, AND LINKING. A PROMISING ALTERNATIVE IS PHOTOCHEMICAL OXIDATION, BUT THIS PROCESS IS AS YET UNOPTIMIZED, POORLY UNDERSTOOD, AND LARGELY LIMITED. PHOT ...

STABILIZATION OF HAZARDOUS WASTE SITES AND RADIOACTIVE URANIUM MILL TAILINGS REQUIRES THAT METHODS BE DEVELOPED TO PREVENT EROSION OF THE PROTECTIVE COVERING APPLIED AT EACH SITE TO CONTAIN THE WASTES. IN THE CASE OF URANIUM MILL TAILINGS A CLAY CAP UP TO SIX FEET THICK IS APPLIED TO PREVENT ESCAPE OF RADIOACTIVE RADON GAS. IN ARID AREAS WHERE VEGETATION IS DIFFICULT TO ESTABLISH, A ROCK MULCH OR ...

"Given the exigency to rein in our nation’s energy consumption and carbon emissions, a nationwide deployment of Geothermal Heat Pumps (GHPs) would help mitigate our demands on the earth’s resources by reducing energy requirements for heating and cooling. Geothermal Heat Pump systems are a proven renewable energy resource that provides significant energy savings as compared to typical heating ...

"Since March 2006, Boulder, Colorado based Cool Energy, Inc. (CEI) has prototyped three generations of a novel low-temperature Stirling engine to generate electricity for low-to-medium temperature (100°C to 250°C) heat sources including solar thermal, geothermal and waste heat. With a marketing name for the SolarHeart® Engine, in its most recent operation in April, 2010, over 1800 watts of out ...

"The large-scale production of nanoparticles of the highest purity will be accomplished by the Eltron Solvent-free Powder Synthesis (ESPS) system described in this proposal. Since conventional particle size reduction methods are unable to reduce particles to the nano-scale and tend to reduce the purity of the powders, the ESPS system has been designed for direct yield of high purity and nano-size ...

"As part of its mission to protect human health and the environment, the U.S. Environmental Protection Agency is dedicated to developing and promoting innovative cleanup strategies that restore contaminated sites to productive use, reduce associated costs, and promote environmental stewardship. However, in adopting this strategy there will be an increasing need to implement a more cost effective, ...

"The oil refining industry is one of the most significant sources of greenhouse gas emissions, with considerable contribution from downstream activities. CO2 emissions from refineries rank third among the stationary producers (after power and cement industries), accounting for about 4% of the global CO2 emissions, approaching 1 billion tons per year. In addition, the oil refineries also emit sig ...

"The environmental Protection Agency is soliciting innovations for the development of small unit drinking water systems that will inactivate contaminants including pesticides, organic pollutants, pharmaceuticals, personal care products, and pathogens. In the US, 85% of all public water systems serve fewer than 3,300 people, thus these water systems are considered small. For providing these small ...

"This SBIR Phase I project will develop an affordable, sensitive, fast-response solution to real-time monitoring of Elemental Carbon (EC). EcoChem will employ a proven sensor technology, the photoemission aerosol sensor (PAS) to detect EC. The PAS photoionizes carbonaceous aerosols with a unique excimer lamp [Burtscher, 1992] whose wavelength is chosen to selectively ionize EX and polycyclic aro ...
