Minnesota National Lakes Assessment Project: Water Mercury Concentrations in Minnesota Lakes

The U.S. Environmental Protection Agency (EPA) has a responsibility to assess the health of the nation's water resources. One of the methods for assessment is a statistically based survey. The Survey of the Nation's Lakes, conducted in 2007, is one of a series of water surveys being conducted by states, tribes, EPA, and other partners. In addition to lakes, partners will also study coastal waters, wadable streams, rivers, and wetlands in a revolving sequence. The purpose of these surveys is to generate statistically valid and environmentally relevant reports on the condition of the nation's streams, lakes, wetlands, and estuaries at nation-wide and regional scales.
