Why Are aquifers important to our freshwater supply? 5TH GRADE ANSWER c:
ANEK [815]

Explanation:

Aquifers are porous and permeable formations that stores ground water. The ground water system is made up of mostly fresh water.

  • An aquifer acts as a reserve for ground water in the environment.
  • By passing through different formations, water that recharges them are purified.
