The Grades are in!

The new 2018 Long Island Sound Report Card has been released.


  • For the first time the Report Card includes 10 years of data and an assessment of how water quality is trending in each region of the Sound.
  • This report gives a welcome stamp of approval for more than a decade’s worth of federal and state investment in improvements to sewage treatment facilities in both Connecticut and New York, conducted with the leadership of EPA.
  • Overall there have been improvements to water quality in the Sound over the past decade, despite increasing population and pressures from a warming climate.
  • The Eastern Narrows, off the coast of Westchester and Nassau Counties, showed the most dramatic improvement going from a D+ in 2008 to a B- in 2017.
  • The most positive results were found in the measurement of dissolved oxygen in the open Sound waters, a crucial barometer for the health of the waterway.

There’s more work to be done:

  • The Western Narrows, home to New York City, remained stalled at an “F” grade (45%) since 2008.
  • Grades only apply to “open water” conditions – individual bays and harbors face continued challenges.
