Conceptual model of flow system of Northern Atlantic Coastal Plain

Block diagram showing conceptual model of the flow system with the Northern Atlantic Coastal Plain aquifer system. The diagram illustrates how water enters the flow system as streamflow across the Fall Line and as recharge from precipitation; this water then leaves the flow system as groundwater is withdrawn by pumping wells or discharges to streams and to the coast. Red arrows indicate inflow from recharge and wastewater return flow, and blue arrows indicate outflow from groundwater discharge to streams and to the coast as well as water removed from private and public-supply wells.
