A warning has been issued in De Pere for a possible chlorine contamination in the city's water system.
A letter was sent to residents stating that the water has recently experienced a problem with the chlorination system in a portion of the city near Lawrence Drive and American Boulevard. Water samples collected from fire hydrants in the areas showed higher levels of chlorine.
Some people could experience irritation to eyes and nose or stomach discomfort. The city says repairs have already been made to the water system.
