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 www.njbeaches.org or www.theswimguide.org before you head out. To report suspicious water quality, call us at 732-888-9870.
