1. An aquifer in which the water table is at atmospheric pressure and where the water is unconfined, allowing direct recharge from precipitation
The phreatic aquifer is more vulnerable to contamination due to its direct contact with the surface.
O aquífero freático é mais vulnerável à contaminação devido ao seu contato direto com a superfície.
2. A groundwater reservoir where the upper surface is exposed to atmospheric pressure through the vadose zone
Farmers rely heavily on water from the phreatic aquifer for irrigation.
Os agricultores dependem muito da água do aquífero freático para irrigação.
