In the 2002 Small Business Innovation Research Solicitation, the U.S. Environmental Protection Agency explicitly expressed interest in instruments that can accurately and reliably measure particulate emissions from vehicles. The availability of suitable instruments for measuring particulate emissions from engines and vehicles will benefit two broad categories of users: (1) it will directly help ...

Contaminated groundwater containing trichloroethylene and similar halogenated hydrocarbons poses a large-scale environmental challenge. Existing treatment methods are imperfect in that they are slow, expensive, fail to treat the full spectrum of groundwater contaminants, and sometimes produce even more toxic partially chlorinated chemical intermediaries. In the past decade, techniques have emerg ...

One of the program areas of interest to the U.S. Environmental Protection Agency (EPA) is the development of rapid, non-invasive monitors to detect exposure to toxic air pollutants at trace (ppt) levels. Of the 356 chemicals listed on the Chemical Emergency Preparedness and Prevention Office¿s List of Extremely Hazardous Substances (Section 302 of the Emergency Planning and Community Right-To-Kn ...

Finishes Unlimited, Inc., produces baking enamels for general purpose original equipment manufacturers who make sundry metal products such as lockers, tool boxes, compressors, folding chairs, storage racks, etc. Although it is a small company, Finishes Unlimited, Inc., has been among the leaders in one type of environmentally friendly coatings (i.e., waterborne bake enamels). In 1993, it became ...

An important approach to limiting the pollution of our Nation¿s natural waters and drinking water supply is the development of field-deployable monitors to detect the presence of pollutants in ground and surface waters. Monitors can alert regulators to the presence of dangerous contaminants before they spread more widely through the ecosystem, thus protecting human health and the environment. I ...

Treatment of water contaminated with volatile organic compounds (VOCs) is a major problem for the U.S. chemical industry. Currently, VOCs are removed from moderately contaminated wastewater streams by processes such as steam stripping, and wastewaters containing low levels of VOCs are treated by air stripping combined with a carbon adsorption off-gas treatment system. Membrane Technology and Res ...

With the maximum contaminant level for arsenic in drinking water decreasing from 50 ppb to 10 ppb in 2006, a heavy financial burden will be placed on small water-treatment facilities serving less than 10,000 people. At present, adsorption on activated alumina is preferred for removing arsenic in these small facilities because this process has relatively low capital costs and low operating expense ...

The problem addressed by this Phase I research project is high emissions from small reciprocating internal combustion engines, particularly in terms of frequent operation at non-ideal revolutions per minute (RPM) and torque loading as well as under cold-start conditions. There is an opportunity to substantially reduce emissions through the use of digitally controlled electric variable valve timin ...

Cryptosporidium parvum, a waterborne pathogen, is a serious threat to the Nation¿s water supply. It does not respond to common antibiotics and resists water purification treatments. It is of interest to not only monitor C. parvum oocysts in drinking water, but also to study their fate in the environment from various sources (e.g., cattle) in lakes and streams. This is especially important to ...
