The State University of New York at Stony Brook created the Long Island Groundwater Research Institute (LIGRI) in 1994 to marshal the resources and expertise of the University for the study of groundwater hydrology and chemistry. One of our goals is to bring the results of scientific research to bear on the region's most pressing groundwater problems. Inquiries on all aspects of groundwater hydrology and chemistry are welcome. LIGRI was established in NY State Law (Chapter 654) in 1997.
The resolution of hydrogeological and groundwater pollution problems requires basic and applied research from a broad array of disciplines. The Institute coordinates and expands the existing potential for research by faculty, staff and students in groundwater hydrology. The Institute maintains close communication with ground-water professionals in the government and private sector in Long Island. Through the University's Center for Regional Policy Studies, a distinguished Advisory Council has been established with representation of agencies with management responsibilities. In 1997 the Institute was formally established by legislative act.
The focus of research is Long Island's aquifer system, which is an ideal natural laboratory. It is self-contained and representative of coastal plain aquifers all along the east coast of the U.S. It has a unique diversity ranging from western Long Island with a densely populated urban environment, through a suburban zone, to farmland, and finally to undeveloped pine barrens in eastern Long Island. Superimposed on each of these zones is a north-south gradient from barrier islands and coastal regions to interior uplands of varied topography. Since the primary flow of groundwater is north and south, there tends to be little intermixing of waters associated with different levels of development. The application of results of high-quality research is essential for the effective management of our groundwater resources.
The University has a long history of groundwater research. We are particularly proud of our contributions in:
groundwater modeling,
geochemical studies,
groundwater impacts on coastal environments,
bioremediation and biodegradation of pollutants.
In addition, the Institute's faculty provides a course of graduate study in groundwater hydrology leading to the degree of Master's of Science. The Institute is served by faculty in the School of Marine and Atmospheric Sciences, the Department of Earth and Space Sciences, and the Department of Applied Mathematics and Statistics.

Environmental Community Assistance Consortium
The Institute is a member of ECAC, joining the Maxwell School and College of Engineering and Computer Science at Syracuse University, the New York Water Resources Institute at Cornell University and the Darrin Fresh Water Institute at the Rensselaer Polytechnic Institute to assist local communities access institutional expertise and resources to provide outreach and education and support government agencies through a state-wide effort.
LIGRI is also part of the Institute for Leadership and Sustainable Development, a joint initiative between the State University of New York and the University of the West Indies.
