Health Risk Limits Rules for Groundwater
Rules Amendments - Contaminants

February 2021

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.

The water guidance values for the contaminants listed below are under consideration for the next Health Risk Limits Rules amendment process. MDH is interested in comments on the proposed values for these contaminants. MDH will publish a Request for Comments later in the year, but welcomes comments or concerns at any time by contacting MDH at health.risk@state.mn.us or 651-201-4899.

This list is subject to change.
