Multiple lines of evidence point to pesticides as stressors affecting invertebrate communities in small streams in five United States regions

Multistressor studies were performed in five regions of the United States to assess the role of pesticides as stressors affecting invertebrate communities in wadable streams. Pesticides and other chemical and physical stressors were measured in 75 to 99 streams per region for 4 weeks, after which invertebrate communities were surveyed (435 total sites). Pesticides were sampled weekly in filtered w

Development of the North Carolina stormwater-treatment decision-support system by using the Stochastic Empirical Loading and Dilution Model (SELDM)

The Federal Highway Administration and State departments of transportation nationwide need an efficient method to assess potential adverse effects of highway stormwater runoff on receiving waters to optimize stormwater-treatment decisions. To this end, the U.S. Geological Survey, in cooperation with the Federal Highway Administration and the North Carolina Department of Transportation (NCDOT), dev

Dead-end hollow fiber ultrafiltration capture of environmental DNA for freshwater mussel (Unionidae) species detection with metabarcoding

Insufficient water sample volumes can be a limiting factor for detecting species with environmental DNA (eDNA) from aquatic habitats. We compared detections of freshwater mussel (Unionidae) communities using large water sample volumes and dead-end hollow fiber ultrafiltration (D-HFUF or DEUF) with traditional eDNA filtration methods that use relatively small water sample volumes. Unionid species w

Monitoring water-quality and geomorphology in the French Broad River during I-26 construction

The North Carolina Department of Transportation (NCDOT) has partnered with the U.S. Geological Survey (USGS) to assess the water-quality and geomorphologic impacts resulting from the I-26 construction projects in western North Carolina. Streamflow, precipitation, and water-quality monitoring data, coupled with periodic assessments of geomorphology, will support the NCDOT construction-site...

Streamflow Measurements Using Salt Dilution Techniques

Salt dilution is a proven method of measuring stream discharge that is widely used around the world but seldom within the U.S. Geological Survey (USGS). This technique is useful at sites where mid-section, ADCP, flume, and volumetric measurement techniques cannot be effectively conducted due to high turbulence, high velocities, and inadequate cross sections. The South Atlantic Water Science Center...
