Groundwater contaminated by sewage from a ruptured septic tank can sometimes be naturally purified by flowing for a relatively short distance through a

sandstone aquifer

spring intersecting the water table

fractured limestone aquifer

The correct option is A) sandstone aquifer

Explanation:

Groundwater can simply be described as water which is present inside the Earth's surface in structures called aquifers. Aquifers are materials which have an ideal porosity and permeability which allow water to flow through them. Aquifers  are materials like sand, silt or rocks.

Sandstone aquifers can trap waste particles like bacteria while allowing the water to easily flow. Hence, they can be used for sewage from a ruptures septic tank.
