A Model of Residential Carrying Capacity for New Jersey, Based on Water Quality

This technical guidance document from the New Jersey Geological Survey presents a methodology that enables the user to estimate the carrying capacity of land in New Jersey for on-site subsurface wastewater disposal systems.

Carrying capacity is defined as the area required per disposal system to generate enough ground-water recharge to dilute that system's effluent to acceptable levels. The carrying-capacity model is a synthesis of two independent models: the Trela-Douglas nitrate-dilution model and the New Jersey Geological Survey's (NJGS) ground-water-recharge model.
