A study of 42 states ranked Wisconsin's tap water as second dirtiest of 42 states, ahead of California, but the city of Eau Claire's utilities administrator says water quality is well within the limits set by the Environmental Protection Agency.
Sam Spanel says there is no benefit to hiding water quality. The city is required to release a yearly report on chemicals detected within the city's water supply.
"If we had a problem with arsenic," says Spanel, "it would show up with this report, or a problem with copper or any other chemical, it would show up in this report that's mailed out to every resident.”
There are chemicals added to help purify drinking water. For example, chlorine prevents bacteria outbreaks, which Spanel calls the water industry's biggest concern.
