Abstract

The report documents groundwater withdrawal and level data for the major aquifers of the New Jersey Coastal Plain. These data have been used in the Regional Aquifer System Analysis flow model of 10 major aquifers in the New Jersey Coastal Plain. Groundwater withdrawal data from more than 1,400 wells are tabulated by year for 1956 through 1980. Total yearly withdrawals for 171 public supply and industrial purveyors for 1918 through 1955 are documented. Best estimates are given for percentages of total withdrawals by aquifer for the 1918 through 1955 data. Groundwater withdrawal data is also tabulated yearly from 1918 through 1980 by county for each aquifer. Long-term hydrographs for 89 Coastal Plain wells provide information on water level fluctuations over time. Potentiometric maps showing earliest recorded water levels in Coastal Plain aquifers delineate prepumping conditions. Groundwater withdrawals from the Coastal Plain have increased from less than 50 million gal/day in 1918 to more than 350 million gal/day in 1980. In response to these increased withdrawals, groundwater levels have been steadily declining. In some areas where wells once flowed freely, water levels are now 100 to 200 ft below land surface.
