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)....

The U.S. Geological Survey, National Park Service, St. Cloud State University, and the University of St. Thomas conducted a cooperative study to investigate the occurrence of chemicals of emerging concern (CECs) and potential effects to aquatic biota in select tributaries of the St. Croix River in Minnesota and Wisconsin. In 2011, treated wastewater effluent samples were collected from 22 sites in the St. Croix River Basin to determine total estrogenic activity. In 2012, wastewater effluent was collected at five select locations based on total estrogenicity and analyzed for CECs. In addition, surface water, bottom sediment, resident fish, and resident crayfish were collected upstream and downstream from effluent...
This data set is a compilation of data from two sampling efforts (2010 and 2014), focused on determining the presence and distribution of organic contaminants throughout the United States portion of the Great Lakes watershed. Water-borne contaminants were monitored in 69 tributaries of the Great Lakes using semipermeable membrane devices (SPMDs), and polar organic chemical integrative samplers (POCIS). Analyses included 185 chemicals (143 detected) including polycyclic aromatic hydrocarbons (PAHs), legacy and current-use pesticides, polychlorinated biphenyls (PCBs), polybrominated diphenyl ether (PBDE) and organophosphate fire retardants, pharmaceuticals, fragrances, industrial chemicals, surfactants, and others.

Background Discharges from non-point sources, municipal and industrial point sources, and combined sewage overflows over the last century resulted in elevated levels of heavy metals, conventional pollutants, phosphorus, and toxic organic contaminants in water and sediments of the Lower Genesee River and Rochester Embayment. As a result, the zooplankton and phytoplankton or “plankton” communities were designated as one of fourteen Beneficial Use Impairments (BUI); i.e., the resource was either impaired or in need of assessment in the Rochester Embayment Area of Concern (AOC). The Rochester Embayment Remedial Action Committee (RAC) was formed by the New York State Department of Environmental Conservation (NYSDEC)...

Onsite wastewater disposal systems (OWDS) in coastal regions of Long Island, New York, contribute bacteria, nutrients, and organic wastewater-associated compounds (including pharmaceuticals, personal care and domestic use products referred to here as contaminants of emerging concern (CECs)) to downgradient shallow groundwater in nearshore settings. Many of the densely populated areas along the East Coast (i.e. Long Island, New York) are served by OWDS. Approximately 75 percent of Suffolk County, New York, residents rely on simple OWDS such as a series of cesspools (ground pits lined with cement blocks or rings without a sealed bottom) and septic systems. Cesspools provide minimal wastewater treatment, typically...
Legacy and emerging contaminants were measured in streams and rivers in the District of Columbia and the states of Maryland, Pennsylvania, Virginia, and West Virginia of the Chesapeake Bay watershed between 2005 and 2013. Passive sampling devices, SPMDs and POCIS, were used to sample these waterbodies, providing a time-integrated concentration of contaminants that are potentially bioavailable to native fishes. This data set is a compilation of data from eight separate studies, all focused on determining the potential exposure of organic chemicals to fish which may be responsible for instances of fish kills and intersex that were observed in these waterbodies.
