<h2>Answer:</h2>
An Aquifer
<h2>Explanation:</h2>
An aquifer is an underground layer of water-bearing permeable rock or unconsolidated materials like gravel, sand, or silt. The most common aquifers are unconsolidated sands and gravels, permeable sedimentary rocks such as sandstones or limestones and heavily fractured volcanic and crystalline rocks. All of these aquifers can be used for the purification of groundwater contaminated by sewage from a ruptured septic tank.
A solution that has a high amount of solute/concentration in the solvent is concentrated because if there is a lot of solute compared to the solvent, then the ratio of solute to solvent is higher, and thus the concentration is higher too.
