Solid waste landfills in Wisconsin are professionally designed, constructed and operated to minimize the risk of pollution. The DNR regulates landfills to prevent negative impacts to people and the environment. Landfills must collect and treat liquids and gases they generate before releasing them to the environment. Landfill operators must monitor their facilities to detect any contamination, report monitoring data to the DNR and respond quickly to any problems. Money is set aside during landfill operation to ensure that monitoring and maintenance continue after the landfill closes. DNR staff inspect landfills regularly.
