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 ...

This Phase I project will investigate using scrap tires to form a protective system for mitigating local scour around bridge piers. Local scour is the erosion of the riverbed around bridge piers, which is induced by the recirculating juncture flow at the intersection of the pier and the riverbed. Bridge failure caused by this phenomenon has long been an important issue with respect to both publi ...

The Clean Air Act of 1990 has raised the concern over trace concentrations of metals in flue gas from electrical generation plants, municipal waste incinerators, and heavy industrial plants. Monitoring will be required to determine the environmental impact and offers an opportunity to empirically minimize it. In flue gas, metals are found in both the vapor state and condensed on fly ash. For sp ...

In this Phase I research project, Material Innovation, Inc., will develop a biodegradable and environmentally benign hydraulic fluid that minimizes hazardous pollution caused by accidental fluid spillage, lowers disposal costs of the used fluid, and helps the user industry to comply with environmental safety regulations. The operating temperature range for this hydraulic fluid will be from -54?C ...

This Phase I project will test the feasibility of converting paper mill sludge or filter-cake (FC), which is typically landfilled or incinerated and is a major environmental concern, into pelletized, composite sorbent of activated carbon and highly porous clay. There are currently more than 500 paper mills in the United States, each generating from 10 to more than 100 dry-tons of FC each day. Th ...

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 ...

The Clean Air Act of 1990 has raised the concern over low trance concentrationsof metals in flue gas from electrical generation plants, municipal wasteincinerators, and heavy industry plants. Monitoring will be required todetermine the extent of the environmental impact and offers an opportunity toempirically minimize it. Here EEI proposes the development of an ultra sensitivecontinuous monitor ...

Developments in on-site spent solvent recovery have implications for reducedenvironmental pollution in the dry cleaning, furniture and paint manufacturingindustries as well as in a range of commercial services. Effluents from solventrecovery operations include fugitive emissions, vent stack gases and water/solvent mixtures. At present, the scale of solvent-recovery operations incertain industrie ...
