Best Available Data on Long Island Sound
Save the Sound works hard to include the most reliable and comprehensive datasets available for this website. As SHE continues to expand, we will update the existing datasets and add new ones to more fully tell the story of the health of Long Island Sound.
The historical data displayed on this website has been collected from the following sources:
Beach Sampling Data
The Water Quality Exchange (WQX) is the mechanism for data partners to submit water monitoring data to EPA.
Boat Launch Sites
Combined Sewer Overflow Outfalls
Embayments (Bays & Harbors) Sampling Data
Land Use & Land Cover
Center for Land Use Education and Research; University of Connecticut, Middlesex County Extension Center
Open Water Sampling Data
Wastewater Treatment Plants
Watershed and Subwatershed Boundaries
The Watershed Boundary Dataset is being developed under the leadership of the Subcommittee on Spatial Water Data, which is part of the Advisory Committee on Water Information (ACWI) and the Federal Geographic Data Committee (FGDC).
