Is groundwater use in Maryland sustainable?
Groundwater supply sustainable yield can be defined as how much water can be withdrawn from an aquifer system, where and for how long, with acceptable physical, economical, environmental, social, cultural, institutional, and legal consequences (Walton and McLane, Groundwater V.51, No. 2, March-April, 2013).
A sustainable supply of clean drinking water is crucial for Maryland's future. Beginning in 2007, studies were initiated to begin to answer the question of acceptable physical (hydraulic) and environmental limits to sustainability. While much has been accomplished, additional research needs to be conducted to protect this vital resource for future generations.
Maryland's groundwater resource (aquifers) are under stress from the cumulative impact of large-scale municipal, irrigation, and industrial wells, in addition to tens of thousands of domestic wells. In some areas of the State current groundwater supplies are inadequate to sustain future water demands.
In 2004, a report by the Governors Advisory Committee on the Management and Protection of the State’s Water Resources ("Wolman" report) recommended a comprehensive study of the sustainability of the aquifer systems in Maryland. In response to this recommendation, the Maryland Geological Survey, in cooperation with the Maryland Department of the Environment, U.S. Geological Survey, and Maryland Department of Natural Resources, initiated comprehensive assessments of the Coastal Plain and fractured rock areas that will provide new scientific information and new data management and analysis tools for the State to use in allocating ground water.
