Rosemount Woods — A Minnesota example of Mercury Exposure

During the late afternoon of September 6 two quart jars of elemental mercury were removed from a nearby shed by two juveniles and taken to a manufactured home community, Rosemount Woods, in Rosemount, Minnesota. During the next 1-2 hours, the mercury was handled and spilled, and children in the community were contaminated with mercury. An outdoor area within the community was also contaminated, as were a few cars. The mercury was tracked into homes, and 13 homes were contaminated above a clearance level considered to be safe for a house (500 nanograms/cubic meter) by the Minnesota Department of Health (MDH).

The mercury spill was reported to the police within 2 hours. The Rosemount Police, Dakota County Special Operations Team and the Minnesota Pollution Control Agency (MPCA) responded and decontaminated and evacuated people to a hotel in Apple Valley. The MPCA, MDH, Rosemount Police and Dakota County Public Health continued with the investigation, decontamination and cleanup of the site, and caring for the evacuated families.

It was found that the decontamination of several children on Monday evening was incomplete, resulting in the contamination of several rooms at the hotel, which was later successfully decontaminated and made safe for occupancy. The decontamination of the children was also completed on Tuesday and Wednesday, and children were evaluated at Regions Hospital by blood and urine and environmentally by mercury vapor meters. Only temporary, minor symptoms of mercury exposure were found in any of the exposed children. Blood and urine monitoring confirmed that mercury levels were decreasing over time.
