Farm Runoff, Precipitation, and Water-Quality Relations
This study identified typical ranges and magnitudes, temporal distributions, and principle factors affecting concentrations and yields of sediment, nutrients, and other constituents in runoff from agricultural fields. The drawing shows water flowing through an agricultural environment.

Streams of the Milwaukee Area
Changes in water quality in urban areas may present themselves in conspicuous ways – such as murky or stinky stream water. They may also present themselves in less conspicuous ways – such as fewer native or pollution sensitive organisms. This drawing is a conglomeration of streams studied in the Milwaukee, WI area.

Nutrients, Mercury, and PCBs
The Lake Michigan Mass Balance Project measured and modeled concentrations of persistent contaminants in air, water sediment, and fish and bird tissues in and around Lake Michigan. This report provided an updated concentration data and load estimates for nutrients, mercury, and PCBs.
