About the Sound Health Explorer

Understanding the Health of Long Island Sound

Save the Sound launched the Sound Health Explorer in 2015 as a tool to increase our understanding of water quality conditions in Long Island Sound and to activate local and regional solutions to improve those conditions. We are striving to make the available water quality data accessible to and understandable by members of the public. Without access to reliable data, water pollution will remain a mystery subject to speculation, or worse, inaction.

Empowered with data, we urge everyone who loves Long Island Sound to educate themselves on their local water quality conditions and local sources of water pollution, and focus on the important task of eliminating those sources and preserving the health of our beloved Sound.

The first iteration of the Sound Health Explorer focuses on the health of our coastal beaches and the bacterial pollution that leads to beach closures and water quality degradation. We have paired the bacterial data with other datasets that further characterize our waterfronts and may assist in identifying contributors to local pollution problems.

Rainfall is also featured on the site, allowing us to see which locations suffer from bacterial contamination as a result of wet weather overflows and runoff, and which locations suffer bacterial contamination in dry weather too. Dry weather contamination points to a very local source of fecal pollution. Wet weather contamination is typically associated with fecal pollution delivered by contaminated stormwater, a local tributary, and/or overflowing sanitary systems in the immediate area (i.e. failing septic systems and cesspools or leaking municipal sewer lines).

Findings and Solutions  shares findings from the Explorer and strategies for reducing water pollution.

This website is intended to share the best and most recent available data from around the Sound with the public. We will be adding more features to showcase data from more groups, including groups that focus on smaller regions within the Sound.
