The number of water samples tested by the Marathon County Health Department Laboratory with unsafe bacteria levels.
Why is this important?
It’s estimated that 20-25% of Wisconsin wells have bacterial contamination, so Marathon County Health Department advises all private well owners to have their well water tested for coliform bacteria and nitrates. If there are infants under six months of age or women of childbearing age drinking the water, it should also be tested for fluoride.
