BURNETT COUNTY, WI (WTAQ) - The state DNR is trying to find out who’s been dumping hazardous wastes in northwest Wisconsin.

Officials said illegal dumping took place the day after Labor Day – when various coatings, paint, and solvent waste was dumped around Siren in Burnett County, and Frederic in Polk County.

The DNR said it also found illegal dumps around Danbury and Webster in Burnett County.

Officials said the dumping took place on both public and private lands – and it poses a health risk to humans, wildlife, and local groundwater supplies. They said the wastes should have been either recycled, or processed for disposal.

Those who run across the illegal dumps – or know who set them up – are being asked to call the DNR’s Tip Line. It’s at 1-800-TIP-WDNR.
