Abstract

During 1986, about 1,460 million gallons per day of freshwater was withdrawn from the surface-, and groundwater resources of Maryland. In addition, more than 6,240 million gallons per day of saline surface water was withdrawn and used primarily for cooling purposes in the generation of electricity. Most freshwater withdrawals (84%) were from surface water sources and were withdrawn and used in the Potomac drainage basin, whereas most groundwater was withdrawn and used in the Upper Chesapeake drainage basin. The Potomac Group aquifers provided the most groundwater (56 million gallons per day). Ten water use categories comprise the major demands on the surface and groundwater resources of the State: public supply, domestic, commercial, industrial, mining, thermoelectric power generation, hydroelectric power generation, agricultural (non-irrigation), irrigation, and aquaculture. Public-supply systems withdrew the most water in the State (801 million gallon/day) for use by residents, commercial establishments, and industries. Baltimore City had the largest public-supply use in 1986 (about 151 million gallons/day). (USGS)
