Health Risk Limits Rules for Groundwater
2014/2015 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 (Minnesota Statutes chapter 103H, section 201, chapter 144, section 12 subdivision 1(5), and Minnesota Session Law 2013, article 2, chapter 137, section 8(a).)
MDH is proposing amendments to the current Health Risk Limit rules (Minnesota Rules,4717.7860 and 4717.7500).
There are currently 12 chemicals with guidance values under consideration for rulemaking (See 2014/2015 Amendments - Contaminants).
