How do wetlands help replenish underground water supplies?

Wetlands play a crucial role in replenishing underground water supplies by allowing rainwater and surface water to infiltrate into the ground. As water percolates through the soil and sediment layers in wetlands, it recharges aquifers, which are underground layers of water-bearing rock. Additionally, the slow movement of water through wetlands helps to filter pollutants, improving the quality of the water that ultimately reaches groundwater systems. This natural process contributes to maintaining regional water balance and supporting ecosystems.
