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...

Description of Work U.S. Geological Survey (USGS) scientists are improving the health of the Great Lakes sport and commercial fisheries by documenting sources and the determining the processes that control mercury entering food webs, and helping to evaluate the implications for public health. Our scientists will provide decision-makers with a scientific understanding of mercury-source profiles, the relative importance of the various sources, and the expected environmental responses to Great Lakes wasters and fisheries to altered mercury loading and restoration actions. This information is intended to inform and maximize the benefit of the Great Lakes restoration program. The USGS will develop mercury and methylmercury...
