MADISON (AP) -- Several Great Lakes communities are competing to reduce pollution by controlling the electricity they consume from the power grid.

Wisconsin Public Radio reports that Bayfield is one of five cities working to lower mercury and other emissions through the Water Utility Energy Challenge.

Carol Miller is a professor of civil and environmental engineering at Wayne State University in Michigan. She says the cities have been testing new technology that tracks pollution and can indicate what time to pump water when lower polluting power sources are providing electricity.

Bayfield Office Assistant Sarah Mather says the city reduced mercury emissions by 25 percent last year by pumping water at certain times of the day. The water utility pumps an average of 60,000 gallons per day.

Competition winners will be announced in June.
