Residents who get their water from private wells and live in flood areas are being urged to have their water tested.
There have been several positive tests for coliform bacteria in private wells in recent weeks, Rock Island County Health Department Director Paul Gusse, said.
"It's significant but not surprising," he said.
The Illinois Department of Public Health has waived testing costs for wells in flood areas because of recent flooding.
However, the county charges a $5 shipping fee to send the water samples collected by residents to the state for testing. Special bottles for testing are available from the health department.
Mr. Gusse said he "highly recommends" residents in flood areas who use wells get their water tested.
He said there have been some positive tests on Campbell's Island in recent weeks.
The health department does not send out notices to individual homeowners in surrounding areas if one sample has been unsatisfactory, Mr. Gusse said, adding that neighboring wells can give different results, even after a flood.
For more information on getting your well tested, call the Rock Island County Health Department's environmental office at 309-558-2840.
