Health Risk Limits Rules for Groundwater
2016/2017 Amendments - Contaminants
MDH proposes amendments to the Health Risk Limits (HRLs) Rules approximately every two years. This allows new and updated human health-based water guidance values to be considered for adoption into rule.
Information about contaminants under consideration for the next amendments proposal is available below. As MDH continues to work on the chemicals under review, additional chemicals could be added to this list if the resulting water guidance is eligible for rule. Further, chemicals could be removed from the list if there is need to re-evaluate the existing guidance.
