Table I Page 1 of 4 Aquifer and Well Characteristics in New Jersey Aquifer Name Aquifer [ Well Characteristics Remarks and Withdrawls 1 Description in 1980 Depth i (Mgal/d)Common Common May Range Range Exceed Coastal Plain Aquifers Ground water occurs generally under water-tcble conditions.

Aquifer Kirkwood-system extends from southern Cohansey Monmouth County aquifer system: to Delaware Bay Sand, quartz, 70 20-350 500- 1,500 and from 12 mi.fine to coarse 1,000 southeast of the grained, pebbly; Delaware River to local clay beds. the Atlantic Ocean.Unconfined.

Aquifer thickness can exceed 350 ft.Brackish and salty water may occur in coastal areas.Atlantic City 800-foot sand: Sand, quartz, medium to coarse grained, gravel, fragmented shell material.Confined.20 450-950 600-800 1,000 Principal confined artesian aquifer supplying water along, the barrier beaches in Cape May, Atlantic, and Ocean Codnties.Aquifer thickness generally ranges between 100 and 150 ft.

Water quality suitable for most purposes.Important source Englishtown of water for Ocean aquifer: Sand, and Monmouth quartz, fine to Counties.

between 60 and 140 ft. Excellent water quality.Highly productive and most used confined aquifer in the Coastal Plain.Aquifer system extends throughout Coastal Plain and Potomac- attains maximum thickness of 4,100 Raritan-Magothyft.

Includes two aquifer system: aquies in Alternating 243 50-1,800 500- 2,000 aquifers in layers of sand, 1,000 northern Coastal grav l, iltandPlain:

aquifers.

Salty water increases with depth and in downdip direction.

Excellent water quality but large iron concentrations in some areas.http://nj.usgs.gov/gw/table_1 .html 6/28/2007 Table I Page 3 of 4 Non-Coastal Plain Aquifers Glacial valley-fill aquifers:

Sand, gravel, interbedded silt and clay.Generally unconfined except where overlain by lake silt and clay or till.10-300 100-1,000 2,000 North of terminal moraine occur principally as channel fill in preglacial stream valleys; south of moraine, as outwash plains and valley trains.Important aquifers in Bergen. Essex and Morris Counties.

Water quality suitable for most uses.Aquifers in the Newark Group: Shale and sandstone:

Shale, sandstone, some conglomerate.

Unconfined to partially confined in upper 200 ft;confined at greater depth.30-1,500 10-500 1,500 Most productive aquifers in Essex, Passaic and Union.Counties.

Water generally hard;may have large concentrations of iron and sulfate.Saltwater has intruded areas of large ground-water withdrawal near bays and estuaries.

Valley and Ridge sedimentary units: Predominantly limestone and shale; some dolomite, calcareous sandstone and siltstone, sandstone, conglomerate and slate.Confined and unconfined.

1,500 150-400 5-500 Highest yields from cavernous limestones and in weathered and fractured zone within 300 ft. of land surface.Locally excessive iron, hardness, and low pH.http://nj.usgs.gov/gw/tablel .html 6/28/2007 Table I Page 4 of 4 Highlands crystalline units: Gneiss, marble, quartzite, pegmatite; some schist, amphibolite and granite. Includes thin belts of conglomerate, sandstone, not significant as aquifers.Confined and unconfined.35-800 5-50 400 Most water obtained from weathered and fractured zone in upper 300 ft; high yields in or near major fault zones.Excellent source of water for domestic use in some areas.Accessibility FOIA Privacy Policies and Notices U.S. Department of the Interior, U.S. Geological Survey URL: http://nj.usgs.gov/gw/table l.html Page Contact Information:
