Groundwater is essential to human life and human activities, but susceptible
to damage through pollution and overuse. Because it is "hidden from
view," its damage may go undetected until it affects human health or
the environment. Cleanup of groundwater can be costly and protracted.
The best way to guarantee continued supplies of clean ground water is
to prevent contamination. Federal and state groundwater programs protect
public water supplies from contaminants that could be harmful to human
health. Other programs direct the cleanup of contaminated sites that
may be polluting the groundwater. For more information about protection
of groundwater, in Michigan contact Michigan
Department of Environmental Quality.
