Withdrawals of ground water and surface water in New Jersey, 1991-92

Abstract

Withdrawals of ground water and surface water in New Jersey were compiled from monthly withdrawal data provided to the New Jersey Department of Environmental Protection by water users with pumping equipment capable of producing 100,000 gallons per day or more. In 1991, withdrawals in New Jersey totaled about 2,110 Mgal/d (million gallons per day)-576 Mgal/d of ground water and 1,534 Mgal/d of surface water. In 1992, withdrawals totaled about 2,090 Mgal/d 571 Mgal/d of ground water and 1,519 Mgal/d of surface water. During 1991-92, withdrawals for public supply averaged 1,099 Mgal/d and supplied 6.8 million residents of the State. Domestic water use averaged 639 Mgal/d, including groundwater withdrawals of 79 Mgal/d and water deliveries from public suppliers of 560 Mgal/d. Commercial water use averaged 227 Mgal/d, including withdrawals of 17 Mgal/d of ground water, 1 Mgal/d of surface water, and water deliveries from public suppliers of 209 Mgal/d. Withdrawals for irrigation averaged 123 Mgal/d, including 22 Mgal/d of ground water and 101 Mgal/d of surface water. Industrial water use in New Jersey averaged 342 Mgal/d during 1991-92, including groundwater withdrawals of 50 Mgal/d, surface-water withdrawals of 193 Mgal/d, and water deliveries from public suppliers of 99 Mgal/d. During 1991-92, average withdrawals for mining use in New Jersey were 33 Mgal/d, including 4 Mgal/d of ground water and 29 Mgal/d of surface water. Withdrawals for thermoelectric-power use averaged 532 Mgal/d, including groundwater withdrawals of 2 Mgal/d, surface-water withdrawals of 508 Mgal/d, and water deliveries from public suppliers of 22 Mgal/d.

Hydrologic and Morphologic Variability of Streams With Different Cranberry Agriculture Histories, Southern New Jersey, United States1

“…Water usage in the cranberry industry, as a whole, is considered nonconsumptive because most of the water used throughout the year is returned within the same drainage from which it was redirected (Clawges and Titus, 1993; Nawyn, 1998; Hoffman and Leiberman, 2000). Data on agricultural water withdrawals in New Jersey are available for the period 1990‐1999 at the hydrologic unit code (HUC) 14 (generally small watersheds of 5‐50 km 2 ) level (Hoffman, 2001) and reveal that the majority of withdrawals in watersheds with extensive cranberry agriculture is derived from diversions of surface water, rather than groundwater resources.…”
