EESS Research Facilities

The Environmental Engineering, Sustainability and Science research group addresses the ability of societies to maintain and improve quality of life while preserving both the quality and availability of its natural resources.

Water Chemistry Laboratory

EESS students testing samples in Wather Chemistry LaboratoryThis facility is equipped for a wide range of studies related to water, waste, sediment, and soil chemistry. It is used for bench- and pilot-scale studies on new treatment processes, and for investigations of physical, chemical, and biological processes that affect the fate and transport of contaminants in aqueous systems. The laboratory meets all requirements for chemical safety.

Microbiology Laboratory

Experimental work pertaining to aquatic microbiology and environmental biotechnology is conducted in this laboratory. The facility is equipped for culture-based and non-culture-based (molecular) microbiology research, measurement, and experimentation. It includes several autoclaves for sterilization, automatic media and culture plate making equipment, three anaerobic glove boxes, a biosafety cabinet for pathogen work, a Zeiss inverted epifluorescence microscope, constant-temperature incubators, a -80C fridge for culture and sample  reservation, several gradient thermocyclers for PCR, an Applied Biosystems 7500 real-time PCR thermocycler, a gel-doc system for digital gel imaging, a DGGE system, and other instruments the isolation, purification, measurement, and manipulation of DNA and RNA. The laboratory is a biosafety level 2 (BSL 2).

Organic Analysis Laboratory

Instrumentation for analysis of organic constituents in water, soil, and air samples is located in this facility. Equipment includes an liquid chromatography MS/MS, a new gas chromatography MS, high-pressure liquid chromatography unit (HPLC) with ultraviolet and fluorescence detectors and an autosampler, a gas chromatography unit (GC) with electron capture and flame ionization detectors (ECD and FID) and an autosampler, a mass spectrometer, a UV-visible spectrophotometer, a total organic carbon (TOC) analyzer, and capillary electrophoresis (CE) unit with autosampler. Other analytical instrumentation in the laboratory includes a BET surface area analyzer; and an Alpkem FS300 flow injection analyzer.

Elemental Analysis Laboratory

This laboratory is used for the analysis of metals and radionuclides and radioactive materials experimentation. The laboratory includes a new inductively coupled plasma mass spectrometer (ICP-MS) for the measurement of a variety of metals and elements. There is also a kinetic phosphorescence analyzer (KPA) for the measurement of uranium, thorium, and americium. Hoods provide class 100 clean spaces for handling samples. 

Ion Chromatography Laboratory

Analyses for low concentrations of specific ionic chemical species in water samples are performed in this facility, which houses a Dionex ion chromatography unit with conductivity and UV detectors. Samples are prepared in an outer room and analyzed via ion chromatography in the inner room.

Environmental Nanotechnology Laboratory

This laboratory is equipped for measurement and study of the properties and behavior of nanomaterials in environmental systems. It supports research on the fate and transport of nanomaterials in water, soil, and sediment.
