The Minnesota Department of Health (MDH) has finished re-evaluating the available data and existing health-based values for acetone and ethylene glycol. The reevaluation was conducted as part of the MDH ongoing Contaminants of Emerging Concern program.
The reevaluation of acetone has resulted in an updated health-based guidance value (HBV) of 3,000 ppb in drinking water, including groundwater. There is an existing Health Risk Limit (HRL) for acetone of 4,000 ppb.
The reevaluation of ethylene glycol has resulted in no change to the Department’s lowest guidance value (2,000 ppb). There is also an existing HRL for ethylene glycol.
