Health Risk Limits Rules for Groundwater
2014/2015 Adopted Amendments - Overview and Links


Health-based guidance for water is a concentration of a chemical (or a mixture of chemicals) in drinking water that is likely to pose little or no health risk to humans. Health Risk Limits (HRLs), a type of health-based guidance, are adopted through a formal rulemaking process authorized in statute

During 2014-2015, MDH proposed amendments to the current Health Risk LImit Rules. The amendments were adopted in November 2015 and became effective December 29, 2015. These updates are now reflected in the Human Health-Based Water Guidance table.
