A residential mercury spill occurred in January 2026 when a child found a container of mercury in a neighbor’s belongings and brought it back to the residence and began to play with it. The mercury was spilled in a bedroom of the residence. After the residents discovered the spill, the residents collected a portion of the mercury and disposed of it in the municipal garbage.

 

Several weeks later, while moving furniture in the house, mercury beads were observed on the carpet of the room. Residents once again attempted to clean up the spill themselves and later called poison control with concerns or mercury poisoning. The residents went to the hospital for assessment, and the local fire department was called to assess the residence. When they entered the home, mercury was observed on the carpet of the house and EPA was notified of the incident.

 

EPA and START mobilized on March 4, 2026, finding elevated ambient mercury concentrations throughout the house and determined further clean up would be necessary.
