Many people think that water pollution is caused by big business or large government facilities - places with pipes leading into the river. These are known as "point source" polluters. However, in recent years these sources have greatly reduced their negative impact on water quality. As a result, storm water runoff is now one of the leading causes of surface water pollution, according to the Illinois Environmental Protection Agency. The Storm Drain Stenciling program has been active since 1992, but stencils wear off and have to be re-stenciled regularly.
