Because areawide lead soil contamination poses significant risks to large populations in the United States, reducing lead levels in these soils is an important environmental health priority. Current methods that address localized, small-scale lead contamination, such as excavation and replacement of soil, are too expensive for large-scale application. This Phase I SBIR project seeks to develop a ...

Passage in 1996 of the Food Quality Protection Act and amendments to the Safe Drinking Water Act reflected concerns regarding food and drinking water safety and required the U.S. Environmental Protection Agency (EPA) to develop a screening program, using appropriate validated test systems and other scientifically relevant information to determine whether certain substances may have an endocrine ef ...

In this proposed Phase I project, we will develop a fiber optic scintillator system with radionuclide-selective cladding for use in the detection of radionuclide contamination in water supplies or wastewater streams. The current terrorist threat requires that vigilance be maintained on all avenues of attack to the United States, including the potential for attack on the country’s food or water ...

The use of enzyme-linked immunosorbent assay (ELISA) to detect contaminants such as solvents, fuels, and pesticides in soil and water samples is now well established. Although ELISA and related methods can facilitate analysis of samples, several washing and separation steps are involved that require 30 to 120 minutes per sample to reach equilibrium. Recently, near infrared fluorescence immunoassa ...

Passage in 1996 of the Food Quality Protection Act (FQPA) and Amendments to the Safe Drinking Water Act (SDW) reflected these concerns and required EPA to develop a screening program, using appropriate validation test systems and other scientifically relevant information, to determine whether certain substances may have an endocrine effect in wildlife and humans. The proposed work will result in ...

A number of industrial processes generate wastewater with mercury contamination. Existing cleanup processes have difficulties in achieving low mercury discharge limits, especially in the presence of competing metal ions already below their discharge limits. Commercial ion exchange media are not selective for mercury, so other metal ions compete with mercury for binding sites. Consequently, excess ...
