Ground Water Management Branch

GWMB

The Ground Water Management Branch of the Division of Water Resources provides technical and management support for the development and use of ground water resources in the State of North Carolina. Staff provides both quantity and quality expertise to understand ground water because it is an essential resource in the State. More than 48% of North Carolina's population receives its drinking water supplies from ground water. This includes 13.5% of all drinking water from public water supplies, and 100% of all self-supplied domestic drinking water supplies (as of 2010, about 35% of the State's population -- 3,300,000 North Carolinians -- received domestic water supplies from private wells). In addition to its use for drinking water, ground water is withdrawn extensively for irrigation and livestock, mining, and for self-supplied commercial and industrial uses (those that are not served by public water supplies).
