A harmful bacteria that contaminated some wells in Winnebago County is showing up once again. The health department had reported an E. Coli problem on Rice Avenue and Vinton Avenue was fixed in February. But many residents’ wells still test positive for E. Coli and coliform bacteria. The problems started in January when a sewer overflowed near the neighborhood. Many residents haven't been able to use their water since.
The levels of E. Coli and coliform in the groundwater have dropped since January according to the Winnebago County Health Department. But for the 20 wells on Rice Avenue and Vinton Avenue, there are still low levels the bacteria. Health department employees say the cause could be anything from septic tanks to animal feces. They're recommending that residents in the effected neighborhood pay for city water.
