Are there health risks presented by the contaminated groundwater?

There are no known health risks from the groundwater. The groundwater is located approximately 180 to 190 feet below ground surface (ft bgs) and there is no known exposure pathway to this water.

Existing water supply wells identified within two miles of the QCLF are generally not of concern as they are completed in a deeper aquifer unit and are not located directly downgradient of the landfill, based on the current groundwater flow direction.
