This summer, the Wisconsin DNR required the Picnic and Group area wells and drinking fountains be closed to the public; they cannot be re-opened until steps are taken to resolve the coliform bacteria problems.

The Homestead Park well has had nitrate levels above safe drinking water standards for six years. During this timeframe, the well/drinking fountains have been closed to the public and bottled drinking water has been purchased for full-time and seasonal park staff. The Homestead well was constructed in 2002. At the time every precaution was taken to avoid nitrate contamination, the well is 325 feet deep, is 10-inches wide with a 6-inch casing going down 313 feet, the cavity between the well and casing is grouted to 303 feet.
