    The water quality at all New Jersey beaches is acceptable for swimming on the eve of the long holiday weekend.

    The New Jersey Department of Environmental Protection monitors bacterial levels at 209 bay, river, and ocean beaches at the Jersey Shore and issues advisories one day following an unacceptable bacteria level. 

    Since monitoring began in late May, 99.9% of beach days were open for bathing, according to the state’s njbeaches.org

    But there have been some swimming advisories and beach closures.

    Last week, two beaches in Ocean County and 13 in Monmouth County were under a swimming advisory due to water samples exceeding a quality standard. Two beaches remained under the advisory the following day and one was closed to swimming.

    The standard for the acceptable level of enterococcus, a bacteria found in the intestines of warm-blooded animals that can cause urinary tract infections, bacteremia, bacterial endocarditis, diverticulitis, and meningitis, is 104 colonies per 100 ml of water.

    Some waterways are typically susceptible to higher bacteria levels after rainfall and associated storm runoff. Onshore flow also pushes in offshore water and keeps near-shore water from flowing adequately out to sea.

    Beaches are closed if two consecutive samples collected at a bathing beach exceed the state standard and remain in effect until subsequent sampling indicates bacteria levels are again below the standard, according to the DEP.
