Long Island Sound Study

Long Island Sound is among the northeast region’s most important and valuable estuaries.

An estuary is an areas where freshwater delivered by rivers and streams flows into the ocean, mixing with salt water.

Long Island Sound provides crucial habitat for a diverse range of plant and animal life, and tourism associated with the Sound contributes an estimated $5.5 billion per year in revenue to the regional economy.

The watershed extends north beyond Connecticut to include parts of Massachusetts, New Hampshire, and Vermont. More than 8 million people live in the Long Island Sound watershed, and the associated development has resulted in an increase in some types of pollution, altered land surfaces, reduced open spaces, and restricted access to the water.

The Long Island Sound Study (LISS) is one of 28 National Estuary Programs funded by EPA under Section 320 of the Clean Water Act. Protecting and restoring the water quality of the Sound is an important goal for NEIWPCC.

The LISS Management Committee

The LISS Management Conference is a partnership of stakeholders representing citizen and environmental groups, businesses and industries, academic institutions, and local, state, and federal governments working to implement the 1994 Comprehensive Conservation and Management Plan (CCMP). As a LISS partner, NEIWPCC is focusing mainly on two components of the CCMP:

  • Involving and educating the public in the restoration
  • Protection of the Sound and assisting as a scientific resource

Sound Health Report

The Sound Health is a report to the public on the environmental issues affecting Long Island Sound that is developed on a biennial bases. It provides information on water quality, the abundance of animal and plant life in the Sound, efforts to restore natural areas, and efforts to increase public access to the waterfront. Each report also highlights special projects or topics.

The report is distributed as an insert in newspapers local to Long Island Sound, as well as through the mail by request and on the LISS website. In addition to educating the general public, Sound Health has become a valuable tool for classroom education.

To view the Sound Health reports electronically, please visit the Long Island Sound Study’s Sound Health webpage.

Printed copies of the report are available upon request from the LISS office, by using the LISS information contact form.
