These tables list the Wisconsin NR 140 public health or welfare related groundwater quality Enforcement Standard (ES), NR 809 drinking water Maximum Contaminant Level (MCL) or Secondary Standard, or lifetime Health Advisory Level (HAL) established by the Wisconsin Dept. of Heath Services (WI DHS) or the United States Environmental Protection Agency (US EPA) for contaminants in groundwater and drinking water.

NR 140 health and welfare based ESs, and NR 809 MCLs are enforceable standards established to protect public health and welfare by limiting the levels of contaminants in groundwater and drinking water. NR 809 Secondary Standards are guidelines established to address cosmetic and aesthetic effects of substances present in drinking water supplies. HALs established by the WI DHS or the US EPA serve as technical guidance to assist regulators with water consumption advisories and groundwater remediation decisions.
