Answer:

During the recharge process, the water infiltrates at the land's surface and flows through the unsaturated zone. It then crosses the water table and enters the groundwater system. Chloride (NaCl) is important and necessary because the sodium ions are held loosely and exchanged easily with calcium and magnesium ions.
