Human Health-Based Water Guidance Table
The Minnesota Department of Health (MDH) develops health-based rules and guidance to evaluate potential human health risks from exposures to chemicals in groundwater. For more information, see: Guidance Values and Standards for Contaminants in Drinking Water or contact the Health Risk Assessment Unit.
Key to table entries
Value Type: HRL = Health Risk Limits; HBV = Health-Based Values; and RAA = Risk Assessment Advice. Subscripts either indicate the last two digits of the year the value was developed or that the HRL is based on a US EPA Maximum Contaminant Level (MCL).
Exposure Duration: Acute = one day exposure; Short-term = greater than one day up to 30 days; Subchronic = greater than 30 days up to 10% of a lifetime; Chronic = greater than 10% of a lifetime; and Cancer = zero to 70 years of age

Other Minnesota Guidance is also available for certain methods and substances, including lead, dioxins, PAHs, Total Petroleum Hydrocarbon (TPH), as well as rapid assessment values for pesticides and pharmaceuticals.
A Comparison of State Water Guidance and Federal Drinking Water Standards is also available.
When multiple substances are present MDH risk assessment methods require evaluation of the potential risk from the combined exposure. Information from the water guidance table below and a calculator for exposures to multiple chemicals is available for download: MDH Water Guidance and Additivity Calculator (Excel).
