Under the Ground Water Management Act of 1992, Virginia manages groundwater through a program regulating the withdrawals of groundwater in certain areas called Groundwater Management Areas (GWMA). Currently, there are two Groundwater Management Areas in the state. The Eastern Virginia Groundwater Management Area comprises all areas east of Interstate 95. The Eastern Shore Groundwater Management Area includes Accomack and Northampton counties. Any person or entity located within a declared GWMA must obtain a permit to withdraw 300,000 gallons or more of groundwater in any one month.
