![]() The effects of the potential increased withdrawals from the Aquia aquifer could be reduced by shifting pumpage to the deeper Magothy aquifer in areas of greatest drawdown.ĮVALUATION OF AQUIA AQUIFER WATER QUALITY.Where potential drawdown is greatest, the brackish-water/freshwater interface could rise by approximately 55 feet to more than 65 feetĪnd pose a risk for existing wells near the shoreline.Potential drawdown from new development on the peninsula is greatest near Glebe Bay, where drawdown could reach approximately 2 feet.Additional withdrawal from the Aquia aquifer resulting from new development will likely result in drawdown (lowering of the water table) of less than 0.25 feet for most of the peninsula.Household water-use rates of 147 and 250 gallons per day, respectively. On water levels in the Aquia aquifer and on the brackish-water/freshwater interface. On the Mayo Peninsula was evaluated using a one-layer numerical groundwater-flow model (MODFLOW) to estimate the effects The potential increase of between 0.093 and 0.158 million gallons per day resulting from the possible new development EFFECTS OF INCREASED WITHDRAWALS FROM THE AQUIA AQUIFER In addition, water quality of the Aquia aquifer, both natural and affectedīy anthropogenic contaminants, that might constrain the use of the aquifer for domestic potable supply was also evaluated. Interface in the Aquia aquifer were evaluated. The potentialĮffects of increased domestic water withdrawals to support the possible growth on water levels and on the brackish-water On the peninsula associated with increased capacity for treating sewage effluent may result in the construction of up toĪpproximately 630 homes (an approximate 20 percent increase over the number of housing units in 2010). The lifting of a building moratorium in 2017 The deeper Magothy aquifer is also utilized but to a much lesser extent. The Mayo Peninsula in east-central Anne Arundel County, Maryland relies primarily on the Aquia aquifer for drinking-water Reports Effects of increased withdrawals from the Aquia aquifer on the Mayo Peninsula, Anne Arundel County, Maryland with an evaluation of water qualityĢ018, Gemperline, J.M., VanDerwerker, T.J., and Andreasen, D.C.
