EXPLANATION

U.S. Geological Survey 7.5-minute quadrangle and name

Outcrop of the Kirkwood Formation

Potentiometric contour—Shows altitude at which water 

 would have stood in a tightly cased well. Dashed where

 approximate. Contour interval is variable

Estimated location of 250-milligram-per-liter line of equal 

 chloride concentration. (Modified from Lacombe and 

 Rosman, 2001)

Approximate updip limit of the Atlantic City 800-foot sand

Surface-water freshwater-saltwater interface (Adapted from

 U.S. Fish and Wildlife Service digital wetland data, 1990)

10,000-milligram-per-liter line of equal chloride concentration 

(Simulated freshwater-saltwater interface, from Pope and Gordon, 1999)

Production well—Upper number is well number; lower number

 is water-level altitude, in feet

Observation well—Upper number is well number; lower number

 is water-level altitude, in feet

Observation well with hydrograph—Upper number is well number;

 lower number is water-level altitude, in feet
