Test Your Well Annually for Bacteria
Bacteria are common contaminants in Wisconsin wells. Bacteria testing looks for signs that the water can make people sick.
- Total coliform bacteria show the well is vulnerable to germs.
- E. coli bacteria show the well is affected by human or animal waste.
If your well has bacteria present, there are steps you can do to protect yourself and your family. For more information contact Marathon County Health Department at 715-261-1908 or visit our website at http://marathoncounty.gov/watertesting.
