quality is a reflection of its watershed. This is true whether
talking about surface water (rivers, streams, lakes, and wetlands)
or groundwater. A watershed is the area that drains to a waterbody.
Almost all watersheds deliver a variety of pollution to their downstream
waterbodies. It is rare for any surface waters to be impacted by
only one source of pollution. With few exceptions, every land-use
activity is a potential source of water pollution. The Illinois
EPA is using watershed management to reduce water pollution.
Watershed management involves all aspects of the
Bureau of Water's activities, including permitting, compliance,
inspections, surveys, and stream investigations of water pollution
as well as public water supply facilities and nontraditional activities
such as watershed resource inventories, watershed management planning
and implementation of watershed management plans.
While the Illinois EPA continues to focus on traditional
programs, the Agency has become more involved with local watershed
management planning committees in an effort to involve citizens
of a watershed in the protection of their local water resources.
