Groundwater Replenished To Prevent Sea Level Rise

Groundwater in Southeastern coastal Virginia is depleting due to over-drafting without intentional replenishment. This phenomenon makes the Potomac aquifer susceptible to saltwater intrusion as well as land subsidence, or the gradual settling or sudden sinking of the earth’s surface. The Hampton Roads Sanitation District responded to these issues by using groundwater augmentation as a way to recharge the aquifer, prevent saltwater intrusion, and potentially increase ground elevation.
