Quizplus · Accepted Answer

The right septic tank is most likely to spread contaminated groundwater far away from the septic tank because it is in limestone with caverns. Limestone is a highly porous and permeable rock which allows water to flow through it easily, and the presence of caverns can increase this permeability even further. This means that any contamination from the septic tank has a higher likelihood of spreading far and wide through the groundwater system.
