Protecting & Restoring Long Island's Peconic Bays

Peconic Estuary Water Quality Status and Trends (2012)

The Suffolk County Department of Health Services (SCDHS) has been monitoring the Peconic Estuary for over four decades (1966-2010). They collected over 18,000 water samples at 158 marine, stream and point source sites and conducted 600,000 measurements of analytes within these water samples. The data was analyzed to determine if trends could be identified and whether efforts to improve water quality in the Estuary have been successful.
