- TABLE 2.4-3 HYDROLOGIC CHARACTERISTICS OF GEOLOGIC FORMATIONS (Youngest to Oldest Formations) Pleistocene Series: Pleistocene deposits occur in this region as thin discontinuous formations and are not a major source of water. Large capacity wells from these deposits are not feasible; however, infiltration galleries have been used in this formation where hydraulically connected to the Delaware River. Shallow wells draw water from these aquifers for domestic suppliers in some area . . Cohansey Sand: The Cohansey Sand outcrops along a line trending northeast-southwest, about 6 miles east of the site. The formation dips to the southeast and therefore is not present at the site. It is composed predominantly of well-sorted sand and gravel, and is potentially the most productive aquifer in the Coastal Plain area. Groundwater in the Cohansey Sand is largely unconfined. There is no significant regional pattern of water movement in the formation. The flow pattern is governed largely by local topography. Kirkwood Formation: The Kirkwood Formation immediately underlies the Pleistocene Soils at the site and dips to the southeast. It is composed of light gray clay with interbedded layers of sand. Domestic and farm water supplies are obtained from wells in the Kirkwood Formation. Yields on the order of 5 to 100 gallons per minute are obtained in the Kirkwood. A few pumping tests have been made in aquifers within the Kirkwood Formation, although none have been documented in the vicinity of the site. The nearest test on record (about 15 1 of 4 SGS-UFSAR Revision 6 February 15, 1987

More often than not, the direction of the hydraulic movement in the Kirkwood Formation does not conform with the direction of dip. The major areas of discharge are probably in the permeable parts of the outcrop area where stream channels, swamps, and marshes provide relatively low-elevation discharge areas. A potentially large natural discharge area occurs where the Kirkwood Formation crops out in the Delaware River. This occurs at the site. Vincetown Formation: This formation is a minor but relatively important source of water in New Jersey. It crops out in the vicinity of the site and is composed of a semi-consolidated sand . In the vicinity of Salem, New Jersey, about 8 miles northeast of the site, wells in the Vincetown Formation have been reported to yield as much as 300 gallons per minute. This is in an area where the granular portion of the aquifer is thicker than normal. At the site the Vincetown Formation contains saline water. Navesink Formation: The Navesink Formation is composed of fine to medium-grained sand with some clay. It is not widely used as a source of water supply in the region. Hornerstown Sand: This formation is composed of sand and clay. It is not used as a source of water supply due to its impermeable nature. However, it is not a tight aquiclude and some vertical leakage may occur into or out of the underlying aquifer, depending upon the hydraulic gradient. Production wells tested at the site in 1970 confirmed that vertical 2 of 4 SGS-UFSAR Revision 6 February 15, 1987 TABLE 2.4-3 (Cont.) occurs in some areas due to in hydraulic Wenonah -Mt. Laurel Sands: These formations function hydrological as a unit; the Wenonah sand is composed mainly of fine to coarse-grained sand and is overlain by the Mt. Laurel sand which is characteristically a medium to coarse-grained sand. This unit is well utilized aquifer, used predominantly for domestic purposes. The aquifer recharges from precipitation and discharges predominantly in low outcrop areas. The aquifer outcrops beneath the Delaware a probable area. Since the is confined and withdrawal volumes are small, it is probably that very little water movement occurs. Operation of onsite wells in the Mount Laurel-Wenonah Formation will induce groundwater flow towards the wells. The Marshalltown Formation is composed of clay, is impermeable, and considered to be an aquiclude. the formation. Its is tapped by wells This sand formation is not utilized as a source of of the site due to a amount of and silt in increases to the north and east, where it up to 200 gallons per minute. Merchantville Clay: This formation is characteristically a clay or sandy clay overlain in many areas by the Woodbury clay, of similar characteristics. In combination with the Woodbury clay, it forms an effective aquiclude. 3 of 4 SGS-UFSAR Revision 25 October 26, 2010 TABLE 2.4-3 {Cont) This formation consists of sand with thin beds of silt and It is a or in much of the area, it is not utilized south and east of the site due to the high chloride content of its water. Aquifer coefficients, based on pump test data, indicate that the Magothy has a permeability value of about 400 gallons per day per square foot. Its porosity is about 45 percent and the specific yield is about 40 percent. The Potomac consists of an upper (Raritan Formation) and a lower fer (Patuxent Formation) by with sand lenses. The movement of groundwater through this generally downdip, or southeast. This aquifer is not formation is used in the vicinity of the site due to its depth and proximity to the salt water-fresh water interface believed to occur about 5000 feet east of the site.

Remainder is obtained from four wells, ranging in depth from 80 to 168 feet, located east of Salem. Four wells ranging in depth from 105 to 240 feet. The wells are probably completed in the Magothy Formation. Two wells, 292 and 360 feet deep. The water probably comes from the Potomac Group. Eight wells; six are about 100 feet deep and the others are about 300 and 350 feet deep. Three wells; two are 80 feet deep and the third is 500 feet deep. The shallow wells probably tap the Mount Laurel-Wenonah Formation

Two wells, 20 feet and 95 feet deep supply the town. The shallower well is used for standby purposes. One well, 272 feet deep, is the source of water supply. Three wells, having depths of 100 feet, 200 feet and 500 feet, supply the town. Two wells, one 26 feet deep in the Wenonah Formation and the other in the Magothy Formation, supply the town. The town obtains water from a shallow infiltration gallery system located in Pleistocene deposits. Revision 6 February 15, 1987 TABLE 2.4-5
