The U.S. Geological Survey (USGS) Nebraska Water Science Center, in cooperation with the City of Omaha, has conducted a combined sewer overflow (CSO) monitoring project to measure the water-quality impacts of CSOs on receiving streams in Omaha, Nebraska.  Constituents analyzed in the samples include organic wastewater compounds (including many endocrine disrupting compounds), nutrients, metals, E. coli, chloride, and others.  The monitoring network includes 11 CSO-monitoring locations, two stormwater-outfall locations, 11 Papillion Creek Basin stream locations, and three Missouri River locations.  The USGS has collected streamflow data at the stream and river locations and water-quality data at all of these locations.  Two sets of water-quality samples have been collected monthly: once on a scheduled date (at the stream and river locations), and once during storm-induced CSO-overflow events (at all 27 locations).  At all but the three Missouri River locations, automatic samplers were used to collect water-quality samples during storm events.  Flow-weighted composite samples from the Missouri River were collected manually by USGS personnel.  These data will be used to determine the occurrence of selected endocrine disrupting compounds in CSO discharges and receiving streams, and to characterize the effect of CSO discharges on water quality of receiving streams.

Jason R. Vogel, Ph.D., USGS Hydrologist Jason R. Vogel has been with the US Geological Survey for five years. During that time he has been the project chief for numerous studies involving chemical and microbial emerging contaminants. Before coming to the USGS, Jason was a research engineer in the Biosystems Engineering department at Oklahoma State University for five years, where he earned his Ph.D. He has published articles and reports on a wide variety of topics including riverbank filtration, pesticides in rain, microbial source tracking, and geostatistics and stochastic design. Vogel also has degrees from the University of Nebraska and Texas A&M University.
