Abstract

Virginia needs a reliable water supply to sustain its growing population and expanding economy. In 1990, the aquifers in the Coastal Plain supplied about 100 million gallons per day (mgd) to the citizens, businesses, and industries of Virginia. It is estimated that by the year 2000, demand will increase by another 10 mgd and likely will continue to increase in future years.

Ground water is the only source of usable water in rural areas of the Coastal Plain and increasingly is being used to support a growing urban population. Current withdrawals have led to declining water levels in most Coastal Plain aquifers. Further declines are likely to occur, posing a threat that saltwater will move into parts of these freshwater aquifers.
