Description of Work U.S. Geological Survey (USGS) is identifying the types and locations of emerging and legacy toxic contaminants in the water and sediments at 59 major tributaries to the Great Lakes (including many Area of Concern sites). This information is needed to help prioritize watersheds for restoration, develop strategies to reduce contaminants, and measure the success of those efforts in meeting restoration goals. The USGS contaminant and virus tributary monitoring network follows the National Monitoring Network for Coastal Waters design. The monitoring effort includes collecting emerging contaminant samples at 17 sites, a subset of the 30 nutrient monitoring sites; and for human viruses and other waterborne...

Description of Work In 2014-15 the U.S. Geological Survey and State University of New York at Fredonia characterized the quantity and morphology of floating microplastics in 29 Great Lakes tributaries in 6 states under different hydrologic conditions, wastewater effluent contributions, land uses, and seasons. Tributaries were sampled four times each, during high-flow and low-flow conditions. Samples were collected from the upper 20-30cm of the stream using a 0.33mm mesh neuston net. Microplastic particles were sorted by size, counted, and categorized as fibers/lines, pellets/beads, foams, films, and fragments. References 1. R. C. Thompson et al., Lost at Sea: Where Is All the Plastic? Science. 304, 838 (2004)....

Description of Work USGS scientists will develop support to State partners for the removal of Beneficial Use Impairments (BUIs) such as fish consumption advisories, fish tumor presence, Eutrophication and unwanted algae, drinking water problems, beach health, and concentrations of PCBs in lake trout and walleyes. Areas of Concern (AOC) principles and guidelines were developed as an initial reference point from which appropriate restoration criteria could be developed. Stage 2 Remedial Action Plans (RAPs) were developed for each of these AOCs to address impairments to any one of 14 beneficial uses associated with these areas. Specific remediation actions are completed in order to restore the beneficial use. When...
