Clean Water

Clean water

Everyone deserves a clean and safe local waterway. Due to polluted stormwater runoff and Combined Sewer Overflows (CSOs), our Estuary’s waters experience high levels of bacteria that make swimming unsafe.

Check out your beach’s water quality at or before you head out. To report suspicious water quality, call us at 732-888-9870.

July 18th: All sites are considered safe to swim in (in fact they were all 20 MPN/100 ml or under, which is great considering the rain) EXCEPT: Rt. 35 Street Bridge in Perth Amboy, which was 63 MPN/100 ml and 2nd Street in Perth Amboy, which was 108 MPN/100ml!
