Streams interact with groundwater in three basic ways: streams gain.In most unconfined aquifers, the specific yield ranges from 10 percent to 30 percent. In other words, of the water held by an aquifer, 10 percent to 30 percent can be given up to pumping or other discharge. A coarse-grained aquifer will have a higher specific yield than a fine-grained one. Specific yield is not to be confused with maximum yield ...

Aquifers can also receive water from surface waters like lakes and rivers. When the aquifer is full, and the water table meets the surface of the ground, water stored in the aquifer can appear at the land surface as a spring or seep. Recharge areas are where aquifers take in water; discharge areas are where groundwater flows to the land surface.

Jan 18, 2023 · TL;DR. Groundwater pollution is a more serious environmental issue than surface water pollution. Groundwater pollution can be harder to detect and clean up due to its underground nature. Surface water pollution is more visible and easier to monitor, but it can still have long-term effects on the environment.
