Firefighting training facilities are of particular hydrogeologic interest due to potential impacts of firefighting foams and fuel sources. Electrical signatures from these impacts should provide resistive targets as both fluids are strongly electrically resistive. Weathering of hydrocarbons is known to produce conductive signatures. Electrical resistivity data were collected one meter down gradient from the secondary containment of a firefighting training area. The data were collected with a 56 electrode array at a one-meter spacing. The results are largely consistent with native geology when compared against the background area. The method did provide precise targets for additional investigation.
