On 7/1/2010, SCDHEC investigated a home in Lexington, SC where it was reported that mercury had been spilled one year prior. The source of the spill may have been an outdated blood pressure monitor. Pooled mercury was found under a carpet in the sagging depression of the floor. Air monitoring found mercury levels above 50 ug/m3 at the front door, above 220 ug/m3 within the living area, and above 25 ug/m3 in the crawl space beneath the home. One of the residents living in the home is several months pregnant. EPA TEL dispatched R1 OSC Negrón to respond to the spill.
