Laboratory Facilities

Graduate students in Environmental Health Sciences have the opportunity to participate closely with faculty on research projects in state-of-the-art laboratory facilities, as well as in field practice settings.

The Industrial Hygiene Laboratory, shared by the IH core faculty, occupies 2,500 sq. ft. and is equipped with the latest instrumentation for measurement of gases, vapors, particulate matter, biological aerosols, noise, radiation, and hazardous materials.

The lab consists of a large room occupied by a wind tunnel, a filter tester, and two biological safety cabinets; a smaller room with a walk-in exposure chamber and two laboratory hoods; a wet-chemistry laboratory with work benches and another lab hood; and several smaller work, storage, and office spaces.

For aerosol research and measurements, the IH Lab has condensation particle counters for measuring nanoparticle concentrations, nephelometers for measuring aerosol mass concentrations, diffusion chargers capable of measuring surface area concentrations, instruments for measuring particle size distributions, samplers for collecting biological aerosols, and numerous gravimetric samplers and cascade impactors. To analyze filter samples, microbalances and microscopes are present.

The IH Lab owns equipment for gas and vapor sampling, including direct reading instruments for measuring ammonia and hydrogen sulfide concentrations and concentrations of organic vapors. The lab also has typical industrial hygiene devices such as flow calibrators, sampling and vacuum pumps, Dräger pumps and tubes, noise dosimeters, velometers, manometers, pressure gauges, pitot tubes, and centrifugal fans. Equipment is available for generating different kinds of gases, vapors, and aerosols for experiments.

The Toxicology Laboratory is equipped with state-of-the-art tissue culture facilities, high-speed centrifuge, rotors, microfuges, speed vac, environmental shaker, visible and UV spectrophotometer, fluorimeter, luminometer polymerase chain reaction (PCR), liquid scintillation counter, dark room, electrophoresis and electroblotting equipment for protein and nucleic acid purification, BioRad Econo System, and chromatography cabinet for doing work at four degrees Centigrade.

The Environmental Chemistry Laboratory is equipped with extraction and processing equipment for trace analysis of environmental samples. The lab includes three GC/MS, one LC/MS, a GC/ECD, and a scintillation counter.

Current laboratory research focuses on understanding the processes that govern organic toxicant behavior in the aquatic environment. Fundamental research in the laboratory is also conducted to develop and test hypotheses of chemical behavior in the “real world.”

The Environmental Chemistry Laboratory participates in a large multiagency effort that is developing a model for use in the Great Lakes that describes toxic chemical behavior. Additional projects concentrate on the relative roles of atmospheric versus nonatmospheric sources of chemicals to the Great Lakes and the state of Minnesota, to aid in the management and regulation of the ecosystem.

Driving Wastewater Treatment Energy Efficiency through a Cohort Training and Implementation Plan
Funding Source: MN Department of Commerce
02/14/2018 – 06/30/2019
The target outcome of this project will be a regional wastewater treatment operations staff cohort training model to achieve energy efficiency. This project seeks to overcome the identified barriers to energy efficiency work through development of a training guide for a facilitated cohort based energy efficiency program at a scale and level appropriate for small to mid-size WWTPs across Minnesota. A key output to this effort will be vetting the training model with key industry stakeholders such as operations management and staff, industry associations and utility providers to address the varied perspectives on the topic. This work will outline program details needed to deliver energy training and activities that motivate site engagement, enable identification of energy efficiency opportunities, and empower implementation of these opportunities to reduce energy intensity of wastewater facilities. In addition, the project seeks to streamline the oversight and cost structure for service delivery to encourage program replication.

Benchmarking activities identify opportunity areas at each facility. Technical assistance uncovers opportunities for reducing waste generated, optimizing water use and wastewater effluent compliance and improving energy efficiency. Implementation support brings needed resources to facilitate implementation of process improvements.Information from this project will be shared broadly through the industry.

LCCMR 2018 Wastewater Treatment Plant Optimization Project
Funding Source: Minnesota Pollution Control Agency / LCCMR prime
10/29/2018 – 12/31/2020
Effective wastewater treatment systems are critical infrastructure to manage waste effluent within hundreds of communities throughout Minnesota. Optimization, in general, means getting better results through existing infrastructure. This project will determine how both mechanical and pond wastewater treatment systems can be optimized, and the new effluent limits met, without adding substantial new infrastructure. Infrastructure improvements should be the last resort when new, or more restrictive effluent limitations are required to meet water quality standards. The goal is to optimize existing wastewater treatment processes to improve nutrient (phosphorus and nitrogen) removal.
