Abstract

The Brunswick Formation of Triassic age is the most important aquifer in the southeastern one-third of Passaic County, N. J. Yields of public supply and industrial wells range from 50 to 510 gal/min and the median yield is 130 gal/min. Most of these wells are 200 to 400 feet deep. The median yield of all public supply and industrial wells over 300 feet deep and 8 inches or larger in diameter is 230 gal/min. Crystalline rocks of Precambrian age are the major source of ground water for domestic use in the northwestern two-thirds of Passaic County. Well yields range from 1 to 200 gal/min. The median yield of domestic wells is 5 gal/min and that of public supply wells is 30 gal/min. Unconsolidated stratified deposits of Quaternary age are potentially an important source of ground water for future development. Yields of wells tapping the stratified deposits range from 4 to 920 gal/min. The median reported yield of domestic wells is 16 gal/min and that of public supply and industrial wells is 130 gal/min. The quality of ground water in Passaic County varies from one aquifer to another. Water from the Precambrian rocks is soft to moderately hard (34 to 104 mg/liter) and is low in dissolved solids (66 to 159 mg/liter). Water from the Brunswick Formation is moderately hard to very hard (89 to 540 mg/liter). The dissolved solids content ranges from 129 to 563 mg/liter. Ground-water pumpage by the major public supply companies in the county has increased from 2.1 million gallons per day in 1951 to 4.39 million gallons per day in 1968. (Woodard-USGS)
