On Dec. 2, OSC Smith responded to a report of a mercury spill at Grayson Middle School in Leitchfield, KY, (NRC #743052). The source of the release occurring originally on Nov. 23 involved a vial of mercury that was being used as a demonstration in a class. The school conducted a minor cleanup themselves. OSC Smith mobilized to the incident at the request of KYDEP to assist in air monitoring using the EPA-owned Lumex mercury analyzer. The class room was checked with the Lumex and results indicated that while a source of mercury was still present, mercury vapor concentrations were well below EPA's removal action level of 2 ug/m3. The school district indicated their intention was to complete the cleanup using a commercially available mercury spill kit. No further EPA action is necessary.
