The water being pumped is at atmospheric pressure and comes from an unconfined aquifer.

Explanation: An unconfined aquifer is open to the atmosphere at the water table, so the groundwater there is at atmospheric pressure and is what pumps normally draw from. Water in a confined aquifer is held under pressure between impermeable layers (it can be artesian and rise above the aquifer) rather than being at atmospheric pressure.
