Environmental Research and Training

The Tuskegee University environmental engineering program offers a broad range of research capabilities, including:

	Research on treatment technologies for soil and wastewater remediation
	Mineral industry environmental technology
	Analytical chemistry oversight
	Site characterization
	Waste treatment/storage/disposal technology development
	Bioremediation of low-level mixed waste
	Training program development for environmental personnel
	Modeling of groundwater contaminant plume transport and application of phosphate grout for contaminant transport limitation
	Advanced oxidation processes for wastewater treatment
	Simulation and laboratory studies on adsoprtion and transport of radionuclides in association with clay-based buffer and backfill materials in repository containers

Research Facilities

The university's multimillion-dollar Carver Research Foundation and George Washington Carver Agricultural Experiment Station have garnered worldwide attention through preeminent research activities in agriculture, the natural sciences and related areas, and other pure and applied sciences. The new Environmental Engineering research laboratory is home to both analytical and process equipment for research in solid waste and wastewater technology development.

Major Equipment

The Environmental Engineering Laboratories at Tuskegee University are equipped and staffed to perform analyses on a variety of sample matrices, such as water, soils, and process gases. Analyses are conducted using state-of-the-art equipment following Environmental Protection Agency protocols and American Society for Testing and Materials procedures. Following are brief descriptions of the primary instruments at the Environmental Engineering Laboratories.

	Hewlett Packard 5890 Gas Chromatograph/Mass Spectrometer: This instrument is a fully automated gas chromatograph and electron impact mass spectrometer and is used for determining the presence/level of pollutants in liquid or solid samples. It provides a broad spectrum of organic analysis and is a valuable tool when sample interference prevents analysis by conventional gas chromatography methods.
	Varian 3400 and Perkin-Elmer 8500 Gas Chromatographs: These instruments are versatile dual-column, temperature-programmable gas chromatographs with several detectors (flame ionization, electron capture and Hot Wire).
	Buck Scientific Model 210 Atomic Absorption Spectrophotometer: This instrument uses a flame mode for the identification and measurement of metals in liquid or solid samples (in parts per million range).
	Hewlett Packard Model 1050 Liquid Chromatograph: This instrument has a high-speed proportioning valve, variable stroke volume, and flow path optimized for mixing blends of up to four solvents. This facilitates mobile-phase preparation, speeds up methods development, and makes flushing the system easy.
	Rosemont Model DC-180 Total Carbon Analyzer: This is an instrument of maximum versatility capable of handling a wide range of concentrations in a variety of water samples. Using UV-promoted persulfate oxidation and nondispersive infrared detection of the CO2 products (which are produced by oxidizing carbonaceous materials), the DC-180 is sensitive from 10 ppb to 30,000 ppm.
	Buck Scientific Model 500 Infrared Spectrophotometer: This instrument uses a high-energy optical design and a sensitive detector for excellent resolution over the full infrared range. Maximum performance is achieved with a fast scanning mechanism that is completely microprocessor driven. The instrument has accessories for solid, liquid, and gas sampling.
