Ground water records for St. Croix, U.S. Virgin Islands, 1969-1973

Ground-water levels at selected wells in St. Croix, the largest of three U.S. Virgin Islands, were monitored from 1969-73. Continuous recording instruments were installed at Mahogany, Castle Coakley, Airport, and Adventure wells, in central St. Croix. Monthly observations of instantaneous ground-mater levels were also made at two wells near Barren Spot and River Gut. Precipitation data from National Weather Service stations near the Mahogany, Airport, and Castle Coakley wells are shown with the water-level data.

Ground water for public supply in St. Croix, Virgin Islands

The ground-water resources of St. Croix, V.I., if properly developed should be adequate to supply the present and near-future demand for water for public supply. Ground water is obtained from weathered volcanic and intrusive rocks (bedrocks), from limestone, and from alluvium. The water obtained from weathered bedrocks and from alluvium in the valleys of the North Side Range is generally of better quality than that obtained elsewhere on the island. The greatest yields are obtained from the limestone and alluvium of the south-central coastal plain, but the water there is generally of poor to only fair quality. In the East End area no water, or salty water, is obtained from wells.
