New Jersey State Swimming Pool Regulations

New Jersey law stipulates how public swimming pools may be designed and operated in the state. These rules help to ensure public safety--improper care and maintenance of public pools can create sanitary and health issues for swimmers. These regulations are covered under New Jersey State Sanitary Code Chapter IX: Public Recreational Bathing.

Facilities

• All public swimming pool facilities must include toilets, showers and dressing rooms. In addition, pool entrances and exits must be at the shallow end. Entrances and exits to the facility on the side next to the deep end of the pool must be separated from the water by at least six feet of deck.

Pool Design

• The pool itself must be made of a non-toxic, watertight material that is capable of enduring design stresses. All surfaces must be slip resistant and smooth. The shape of the pool must avoid "protrusions, means of entanglement or other obstructions in the swimming area" that may cause injury. The pool must have ladders and stairs for exit and entry to any area with water deeper than 24 inches.

Sanitation

• Pools must have surface skimming systems as well as water circulation systems consisting of pumps, piping, suction outlets and filters. The circulation system must be able to "turn over" all of the pool water every eight hours. The water must be "continuously disinfected" by a disinfecting agent, such as chlorine. Disinfectant levels must be monitored every two hours during operating hours.

Water

• Swimming pools are required under New Jersey law to have "a potable water supply and sanitary disposal facilities." The water may be either fresh or salt water. Pool water must be sampled weekly or biweekly if the water has had three months of "consecutive satisfactory sample results." The New Jersey Sanitation code states that the sample must be taken 18 inches below the water in a sterile container held near its base at a 45-degree angle. The container must be lowered vertically into the water and must be filled during the first attempt. Samplers must not rinse the container, allow the test to be contaminated or touch the inner surface of the container. The sample must be taken to a certified laboratory within six hours of collection. In addition, the pool's pH level must be checked every two hours.

Closures

• A health authority or his agent may shut down swimming pools if they are considered a threat to public health. According to New Jersey law, the following are grounds for closure: poor maintenance or lack of equipment or structures, lack of personnel, failure to meet water quality standards or any other condition "which poses an immediate health or safety hazard."
