What term refers to underground layers storing groundwater for drinking?

Explanation:
Underground layers that store and transmit groundwater for drinking are called aquifers. They are permeable formations—like sandstone or gravel—that hold water in connected pore spaces and can yield it to wells. Some aquifers are unconfined with a water table that rises and falls with rainfall; others are confined between impermeable layers. Fracking relates to extracting oil or gas, groundwater pollution refers to contamination, and decomposing bacteria are microorganisms, not storage terms. So the term that fits is aquifers—the natural underground reservoirs that supply drinking water.
