Environmental nonprofit Save the Sound has released its annual water quality report card, grading more than 50 bays and four basins of open water in Long Island Sound. Scientists said the results are encouraging, but there’s still work to be done.

Suffolk County voters get to choose this November about whether to fund a water quality improvement plan through a sales tax increase.
