People are asked to avoid contact with a portion of the Grand River following a sewage spill that's released at least a million gallons of human waste.
A no body contact advisory affects an area about a mile east of the U.S. 31 bridge over the Grand River and downstream to Lake Michigan.
"It's a health hazard, you don't want to swim in polluted water, you don't want to swim in water that has e-coli which is the bacteria we have in sewage....you can get sick," says Jim Hegarty an engineer with Spring Lake.
It's believed a pipe from Spring Lake to Grand Haven is under pressure and has been releasing about 500,000 gallons each day since Friday, Feb. 24, said Dave Krohn, the superintendent of the Grand Haven-Spring Lake Sewer Authority.
Officials aren't sure of the cause of the spill. Divers have been in the water since late Sunday as part of an effort to stop the spill, Krohn said.
Although cold water likely will deter many from jumping in, officials say people should avoid body contact and not submerge themselves into the water until the advisory is lifted.
Crews will be back on the water for Tuesday morning, they plan to have the leak fixed by noon.
Anyone with questions can call the Grand Haven-Spring Lake Sewer Authority at 616-847-3486.
