Groundwater vulnerability (FL) |
To predict the vulnerability of Florida’s major aquifer systems to contamination the Florida Geological Survey is developing the Florida Aquifer Vulnerability Assessment (FAVA) model. FAVA differs from the EPA’s DRASTIC model in that the newer technique accounts for karst terrain. |
