An oil truck rollover caused a spill in Monroe on Monday morning and clean up efforts are underway. Firefighters were called to a report of a gas truck rollover at the intersection of Hattertown Road and Guinea Road around 5:30 a.m. Investigators said the oil truck was full at 3,300 gallons. Environmental clean up teams were called to the area and helped remove the fuel truck. DEEP is now bringing in a contractor to test the well water in the Hattertown Road area.
