Design and methods of the U.S. Geological Survey Northeast Stream Quality Assessment (NESQA), 2016
During 2016, as part of the National Water-Quality Assessment Project (NAWQA), the U.S. Geological Survey conducted the Northeast Stream Quality Assessment (NESQA) to investigate stream quality in the northeastern United States. The goal of the NESQA was to assess the health of wadeable streams in the region by characterizing multiple water-...Coles, James F.; Riva-Murray, Karen; Van Metre, Peter C.; Button, Daniel T.; Bell, Amanda H.; Qi, Sharon L.; Journey, Celeste A.; Sheibley, Richard W.
Effects of urban multi-stressors on three stream biotic assemblages
During 2014, the U.S. Geological Survey (USGS) National Water-Quality Assessment(NAWQA) project assessed stream quality in 75 streams across an urban disturbance gradient within the Piedmont ecoregion of southeastern United States. Our objectives were to identify primary instream stressors affecting algal, macroinvertebrate...Waite, Ian R.; Munn, Mark D.; Moran, Patrick W.; Konrad, Christopher P.; Nowell, Lisa H.; Meador, Michael R.; Van Metre, Peter C.; Carlisle, Daren M.
Linking the agricultural landscape of the Midwest to stream health with structural equation modeling
Multiple physical and chemical stressors can simultaneously affect the biological condition of streams. To better understand the complex interactions of land-use practices, water quality, and ecological integrity of streams, the U.S. Geological Survey National Water Quality Assessment Project is conducting regional-scale assessments of stream...Schmidt, Travis S.; Van Metre, Peter C.; Carlisle, Daren M.
Mixed-chemical exposure and predicted effects potential in wadeable southeastern USA streams
Complex chemical mixtures have been widely reported in larger streams but relatively little work has been done to characterize them and assess their potential effects in headwaterstreams. In 2014, the United States Geological Survey (USGS) sampled 54 Piedmont streams over ten weeks and measured 475 unique organic compounds...Bradley, Paul M.; Journey, Celeste A.; Berninger, Jason P.; Button, Daniel T.; Clark, Jimmy M.; Corsi, Steven R.; DeCicco, Laura A.; Hopkins, Kristina G.; Huffman, Bradley J.; Nakagaki, Naomi; Norman, Julia E.; Nowell, Lisa H.; Qi, Sharon L.; Van Metre, Peter C.; Waite, Ian R.
Nutrient enrichment in wadeable urban streams in the piedmont ecoregion of the southeastern United States
The U.S. Geological Survey (USGS) Southeastern Stream Quality Assessment (SESQA) collected weekly samples for nitrogen and phosphorus in 76 wadeable streams in the urbanized Piedmont ecoregion of the Southeastern United States, during April–June 2014. Total nitrogen (TN) concentrations in excess of EPA guidelines and statistically greater than at...Journey, Celeste A.; Van Metre, Peter C.; Button, Daniel T.; Clark, Jimmy M.; Munn, Mark D.; Nakagaki, Naomi; Qi, Sharon L.; Waite, Ian R.; Bradley, Paul M.
The Midwest Stream Quality Assessment—Influences of human activities on streams
Healthy streams and the fish and other organisms that live in them contribute to our quality of life. Extensive modification of the landscape in the Midwestern United States, however, has profoundly affected the condition of streams. Row crops and pavement have replaced grasslands and woodlands, streams have been straightened, and wetlands and...Van Metre, Peter C.; Mahler, Barbara J.; Carlisle, Daren M.; Coles, James F.
Complex mixtures of dissolved pesticides show potential aquatic toxicity in a synoptic study of Midwestern U.S. streams
Aquatic organisms in streams are exposed to pesticide mixtures that vary in composition over time in response to changes in flow conditions, pesticide inputs to the stream, and pesticide fate and degradation within the stream. To characterize mixtures of dissolved-phase pesticides and degradates in Midwestern streams, a synoptic study was...Nowell, Lisa H.; Moran, Patrick W.; Schmidt, Travis S.; Norman, Julia E.; Nakagaki, Naomi; Shoda, Megan E.; Mahler, Barbara J.; Van Metre, Peter C.; Stone, Wesley W.; Sandstrom, Mark W.; Hladik, Michelle L.
Influence of sediment chemistry and sediment toxicity on macroinvertebrate communities across 99 wadable streams of the Midwestern USA
Simultaneous assessment of sediment chemistry, sediment toxicity, and macroinvertebrate communities can provide multiple lines of evidence when investigating relations between sediment contaminants and ecological degradation. These three measures were evaluated at 99 wadable stream sites across 11 states in the Midwestern United States during the...Moran, Patrick W.; Nowell, Lisa H.; Kemble, Nile E.; Mahler, Barbara J.; Waite, Ian R.; Van Metre, Peter C.
Design and methods of the Midwest Stream Quality Assessment (MSQA), 2013
During 2013, the U.S. Geological Survey (USGS) National Water-Quality Assessment Project (NAWQA), in collaboration with the USGS Columbia Environmental Research Center, the U.S. Environmental Protection Agency (EPA) National Rivers and Streams Assessment (NRSA), and the EPA Office of Pesticide Programs assessed stream quality across the Midwestern...Garrett, Jessica D.; Frey, Jeffrey W.; Van Metre, Peter C.; Journey, Celeste A.; Nakagaki, Naomi; Button, Daniel T.; Nowell, Lisa H.
Multistressor predictive models of invertebrate condition in the Corn Belt, USA
Understanding the complex relations between multiple environmental stressors and ecological conditions in streams can help guide resource-management decisions. During 14 weeks in spring/summer 2013, personnel from the US Geological Survey and the US Environmental Protection Agency sampled 98 wadeable streams across the Midwest Corn Belt region of...Waite, Ian R.; Van Metre, Peter C.
Complex mixtures of Pesticides in Midwest U.S. streams indicated by POCIS time-integrating samplers
The Midwest United States is an intensely agricultural region where pesticides in streams pose risks to aquatic biota, but temporal variability in pesticide concentrations makes characterization of their exposure to organisms challenging. To compensate for the effects of temporal variability, we deployed polar organic chemical integrative samplers...Van Metre, Peter C.; Alvarez, David; Mahler, Barbara J.; Nowell, Lisa H.; Sandstrom, Mark W.; Moran, Patrick W.
Sources and ages of fine-grained sediment to streams using fallout radionuclides in the Midwestern United States
Fallout radionuclides, 7Be and 210Pbex, sampled in bed sediment for 99 watersheds in the Midwestern region of the United States and in 15 samples of suspended sediment from 3 of these watersheds were used to partition upland from channel sources and to estimate the age or the time since the surface-derived portion of sediment was on the...Gellis, Allen; Fuller, Christopher C.; Van Metre, Peter C.
