The Budget Rental Car Site was a former retail gasoline and diesel service station existing on approximately 3 acres located in Louisville Kentucky, USA. The investigation and corrective action work conducted at the facility was under the oversight of the Kentucky (KY) Department for Environmental Protection (KDEP), Division of Waste Management (DWM), Underground Storage Tank Branch (USTB).
Investigations and remediation of petroleum releases to the subsurface had been conducted at the terminal since the underground storage tank systems were removed from a common tank pit in 1997. Subsurface impacts have historically included accumulations of petroleum hydrocarbons in soils, accumulation of light non-aqueous phase liquids (LNAPL) in monitoring wells MW-3, MW-5 and MW-6, and aqueous phase (dissolved) benzene in groundwater as high as 11 milligrams per liter (mg/L).
The impacted area immediately surrounding the former tank pit, occupies approximately 7,000 square feet (ft) and had both soil and groundwater impacts.
