Where does groundwater come from and where does it go?
How do aquifers receive recharge?
Groundwater stored in aquifers comes mainly from rainfall. Depending on the type of aquifers this could be rainfall that occurred recently or up to thousands of years ago. Water can also seep through the ground surface and down to the
How does groundwater discharge from aquifers?
Groundwater flows through an aquifer until it reaches a discharge point such as a stream, river, wetland, spring or even the ocean. It can also flow into another
Water balances are used to describe the relative importance in the major inflows (recharge) and outflows (discharge) of an aquifer.
