MILWAUKEE -- Records show there are eight sites in Wisconsin where potentially dangerous cables that were once used to power U.S. Coast Guard lights could be buried underground.
Such a cable caused an explosion at a crowded Rhode Island beach last summer and injured a woman. Coast Guard records provided to The Associated Press show similar cables are buried under beaches, harbors and waterways at 48 sites in 12 states.
The cables powered lighthouses, buoys and other beacons that have since been converted to solar power. Scientists say the explosion in Narragansett, Rhode Island, was probably caused by hydrogen that built up around a corroded underground cable.
The Wisconsin sites include: Bayfield Harbor South Breakwater Light, Superior Entry South Breakwater Light, Kenosha Light, Milwaukee Breakwater Light, Milwaukee Pierhead Light, Sheboygan North Pierhead Light, Manitowoc Breakwater Light and Two Rivers North Pierhead Light.
