Understanding Great Salt Lake Dust and Air Quality
The Great Salt Lake is the largest saltwater lake in the Western Hemisphere, fed by the Bear, Jordan, and Weber rivers. The lake is a terminal lake, meaning pollutants build up within it rather than flushing downstream. Sediments in the lakebed contain elevated levels of natural and human-caused compounds, such as arsenic. As the lake…
