Experimental Stream Facility (ESF), Clermont County, OH

The Experimental Stream Facility (ESF) is one of only a handful of research facilities in the U.S. designed to conduct small stream research. The facility has eight stream mesocosms that provide a balance between the benefits of a controlled laboratory study (e.g. controlled flow rates, solar irradiance and streambed type) and the benefits of a field study.  This allows researchers to study how pollutant loads interact with important characteristics of stream habitat that may or may not change as a result of anthropogenic stress.

Changes to the stream ecosystem structure and function can be measured and observed in ways that are not possible in field or laboratory studies.  Well designed and controlled experimental stream mesocosm studies can represent a primary tool providing the process-level understanding necessary to move basic research and development from the laboratory bench-top to field applications. ESF studies are designed to gain information on both watershed management and the impact of contaminants of concern. Learn more about ESF research.

Greening EPA. Our parking lot is an experiment in permeable surfaces! The lot covers about one acre and provides parking for employees and visitors. The lot slopes so water flows across the driving lanes between the porous sections. Partially buried tanks receive water drained from lined sections of the permeable parking lanes, allowing researchers to measure volume and flow rates and also study stormwater quality. Monitoring instruments are installed in and beneath the porous pavement to understand the movement of stormwater through the pavement, underlying layers, and into the native soil. Six rain garden cells will help reduce stormwater runoff from non-porous sections of the parking lot and the roof of the adjacent building. Measurements will enable scientists to determine whether permeable surfaces will help cities: cool more effectively during summer evenings than areas paved with conventional surfaces; reduce stormwater volume flowing to receiving waters; and improve water quality by removing solids and other environmental contaminants. All of the rain falling on the parking lot will infiltrate into the soil with no runoff reducing the environmental footprint of our EPA facility.
