Under current conditions, the Old Total Gas Station - Caro property poses no public health hazard. There are very high concentrations of benzene, ethylbenzene, lead, manganese, toluene, and xylenes in the groundwater and subsurface soil on the property, probably because of leaks from the underground gasoline storage tanks on the property. Human exposure to these chemicals might pose health hazards, but there is no current exposure to the contaminated soil and water.
The volatile organic chemicals in the groundwater might volatilize and migrate into basements above the contaminant plume. There is no information available on the extent of the plume or on analysis of basement air from the property vicinity.
While excavating on the property, take appropriate precautions to minimize worker and public exposure to the contaminated subsurface soil and groundwater by both direct contact and inhalation.
Do not use the shallow groundwater on the property for any household purpose.
Consider further investigation to establish the extent of the contamination plume in the groundwater.
Consider sampling of air from nearby basements to determine whether volatile contaminants from the groundwater have reached them.
New environmental data or information concerning the future use of this property may require additional health consultations.
