Site Description
Mercury spill at a residence and school.
Location
XXXX Meadowdale Dr, Williamston, MI 48895
Description of Threat
An estimated 1-2 lbs of mercury were spilled by a 12-year old inside his home and in a school parking lot. The child had possession of the mercury starting around May. The boy is under going medical treatment due to mercury exposure. The mercury was brought to the residence after the sale of a family member's home.
Preliminary Removal Assessment/Removal Site Inspection Results
Ingham County Health Department found mercury as high as 25,000 ng/m3 in a duffel bag inside the child's room. Other areas of the house including the bedrooms of two other children showed mercury had been tracked from the child's room to other rooms of the house. The Health Department also found mercury in the school parking lot where the child said the mercury vial had been dropped.
Due to the severity of the medical condition, Michigan Department of Community Health recommended a breathing zone clearance level of 200 ng/m3 (ATSDR guidance is 1,000 ng/m3) for the child.

Anticipated Activities
EPA will complete the removal of carpeting and household items today. The goal is to lower the downstairs of the home to less than 200 ng/m3 so the child can move back into the downstairs while the homeowner continues to heat and vent the upstairs. The current mercury levels in the upstairs range from 500-1000 ng/m3. Over the next couple weeks, the Ingham County Health Department will rescreen the upstairs.
EPA will cleanup the school parking lot this afternoon.
It is anticipated EPA cleanup work will be completed by Sunday. The roll-off box containing the contaminated items will be picked up as soon as the waste profile has been approved (7-10 days).
