In 2025, water quality at Long Island Sound beaches in Nassau and Suffolk counties showed improvement, with 81 out of 90 beaches receiving A or B ratings, according to a report by the environmental nonprofit Save the Sound. Notable A+ beaches include Sea Cliff Beach and Hobart Beach Inlet. However, Baiting Hollow Camp received a C-, and several others scored lower, prompting potential restoration considerations for consistently low-rated beaches.
The report, released before the summer swimming season, is based on data from local health departments. Oyster Bay Town Supervisor Joseph Saladino highlighted the importance of these ratings for local economy and quality of life.
Water quality is assessed by analyzing samples for fecal contamination and bacteria levels. Factors contributing to high bacteria levels include failing septic systems, leaking sewer pipes, and wildlife waste. Save the Sound advocates for green infrastructure solutions to mitigate stormwater impact and improve water quality, making data accessible to encourage public engagement in environmental advocacy.
