Water Supply Critical Areasby Richard Kropp, NJ Dep of Environmental Protection, United States,

Abstract: Due to the serious overuse of groundwater resources which has led to the continued decline of the potentiometric surface of certain aquifers below sea level, and to real and potential salt water intrusion, the State of New Jersey has declared two Water Supply Critical Areas. Within each Critical Area there is a depleted and threatened portion for each critical aquifer. The boundaries for the depleted portion were developed based upon 1983 aquifer water level data for the minus thirty foot (mean sea level) potentiometric contour. As a result of studies performed with the United States Geological Survey, it has been determined that water users withdrawing from the depleted portion of the aquifer must achieve the following reductions in their 1983 pumpage.
