WATER SUPPLY IN NORTH CAROLINA COASTAL PLAIN
BY WILLARD BERRY
In the last several years increased drilling for water in the Coastal Plain has permitted a better understanding of the subsurface geology. Some areas where more intensive operations have been undertaken show abundant water at the depths of 250 and 500 feet. In the areas south of the Neuse River the Trent limestone is an important water horizon. Below the Trent water may be found in older beds, but in the few wells deeper than about 500 feet the water has been salt or otherwise unusable. North of the Neuse River the Miocene seems to be one of the chief horizons. Water is produced from the Patuxent (Cretaceous) but its quality is not so good as that from the younger rocks.
Throughout the eastern portion of the Coastal Plain wells more than about 500 feet may reach salt waters, apparently . . .
