HOLMEN, Wis. -

Fluoride will be back in the water in the village of Holmen.

Five years ago, voters approved a referendum to add fluoride to the water. It happened for about a week, but then stopped because village board memebers wanted to change to newly approved guidelines.

The board's decision Thursday night was never whether or not to add the chemical to the water, just how to do it.

With a four to three vote, the board members opted to pay a company to engineer and design new equipment for wells to handle sodium fluoride.

If the designs are approved, the equipment is estimated to cost up to $72,000.
