The Kirkwood-Cohansey aquifer system underlies most of the New Jersey Pinelands. The interaction between groundwater and surface waters associated with this aquifer is among the most important factors influencing the structure and function of the Pinelands ecosystem. An important feature of the region is the trillions of gallons of freshwater stored within the area's streams and aquifer systems (Rhodehamel, 1970). Demand for water from the Kirkwood-Cohansey aquifer system is increasing as growth and development occur within the Pinelands and nearby metropolitan areas. The potential effects of these increased water demands are a concern for many State and municipal agencies.
