why might the ground subside after groundwater is pumped to the surface? why might the ground subside after groundwater is pumped to the surface? as water is withdrawn, some sediment is lost with it, and the remaining sediment is left to support the weight on top of it. as a result, the sediment packs more closely together, causing the ground to subside. as water is recharged, the water pressure drops, and the sediment is left to support the weight on top of it. as a result, the sediment packs more closely together, causing the ground to subside. as water is withdrawn, the water pressure drops, and the underground caverns it had created in the limestone bedrock collapse, causing the ground to subside. as water is withdrawn, the water increases, and the sediment is left to support the weight on top of it. as a result, the sediment packs more closely together, causing the ground to subside. as water is withdrawn, the water pressure drops, and the sediment is left to support the weight on top of it. as a result, the sediment packs more closely together, causing the ground to subside.
