Simulation of Groundwater Mounding beneath Hypothetical Stormwater Infiltration Basins

The NJ Coastal Plain RASA (Regional Aquifer System Analysis) model (in this document referred to simply as “the RASA model”) is one of the most widely used models by hydrologists in the NJWSC. This model was developed as part of the RASA program, which was started in 1978 after a congressional mandate to develop quantitative appraisals of the major groundwater systems of the United States.

The hydroecological integrity assessment process (HIP) has been fully developed for the State of New Jersey (NJHIP). The New Jersey Department of Environmental Protection is in the process of applying ecologically relevant ecological flow goals (ERHI's) from the NJHIP to current and future regulation of New Jersey streams. It is the goal of NJDEP to evaluate potential impacts of a proposed water...

Gasoline spills from leaking underground storage tanks is the most common mechanism of subsurface point source contamination. The U.S. Geological Survey's Toxic Substances Hydrology Program investigated the fate and transport of hydrocarbons in the unsaturated zone and shallow groundwater at a gasoline-spill site in Galloway Township, New Jersey.
