To understand the effects of projected increased demands on ground water to supply water, a finite-difference, steady-state, nine-layer, groundwater flow model was used to simulate groundwater flow in the Coastal Plain sediments of southern New Castle County, Delaware.

Results are published in DGS RI   The Delaware Geological Survey (DGS) is installing 7, feet of wells at eight sites in southern New Castle and northern Kent counties to improve groundwater-monitoring efforts, supported by a $, grant from the Delaware Department of Natural Resources and Environmental Control (DNREC).

Department of Natural Resources and Environmental Control.; Geological Survey (U.S.)]. Flow in three aquifers of the Potomac Formation in New Castle County, Delaware, was simulated.

Results of the calibrated flow model show the maximum transmissivity of the lower aquifer is between 1, and 1, square feet per day; the middle aquifer, between 3, and 3, square feet per day; and the upper aquifer, between 5, and 6, square feet per day.

To understand the effects of projected increased demands on groundwater for water supply, a finite-difference, steady-state, groundwater flow model was used to simulate groundwater flow in the Coastal Plain sediments of southern New Castle County, Delaware.

The model simulated flow in the Columbia (water table), Rancocas, Mt. Laurel, combined Magothy/Potomac A, Potomac B, and Potomac. Control reported that ground-water use for public supply in was billion gallons of a total ground-water withdrawal of billion gallons.

The largest development of ground water is for public and industrial supply in intensely populated areas of New Castle County (fig. M), where the Potomac aquifer is the primary by: 1.

Vogel and Andrew G. Reif U.S. GEOLOGICAL SURVEY Water-Resources Investigations Report Prepared in cooperation with the CHESTER Cited by: 4.

The square-mile Red Clay Creek Basin, located in the lower Delaware River Basin, is underlain primarily by metamorphic rocks that range from Precambrian to Lower Paleozoic in age. Ground water flows through secondary openings in fractured crystalline rock and through primary openings below the water table in the overlying saprolite.

This has mainly occurred in coastal New Castle and coastal Sussex counties. Water Quality and Quantity.

Ground-water flow was simulated in 10 aquifers and 9 intervening confining units of the New Jersey Coastal Plain, which consists of unconsolidated gravel, sand, silt, Author: Daryll Pope. Confined Aquifer Wells. Confined aquifers are aquifers that are overlain by a low permeability, confining layer, often made up of clay.

The confining layer may offer some protection from surface contamination. The groundwater below the confining layer is under pressure greater than atmospheric and if penetrated with a well, the water level can rise above the top of the aquifer.

While some drinking water in Delaware comes from groundwater sources (after it has been treated), other drinking water comes from surface sources like rivers (again, treated before it is sent to homes and businesses).

Ground water may exist near to the land surface (less than 10 feet down) or it may occur at depths of up to to several hundred feet.

The underground rock units in which the ground water occurs are called "aquifers". These aquifers are large and deep expanses of rock that lie below the land surface.

The Artesian Water Company public water system is supplied with water from 50 wells located throughout northern New Castle County. These wells are in the Columbia, Potomac, Cockeysville Marble and Mount Laurel formations.
