Background information and definitions
Leaking septic systems are a major cause of groundwater pollution. Septic systems installed in karst areas are particularly likely to fail due to thin soils, sloping topography and unstable foundations. Pollution from septic systems can degrade underground habitats (e.g. Graening & Brown 2003), with potential impacts on roosting bats.
