The New Jersey State Department of Health has set bacterial and chemical standards for public recreational bathing waters (N.J.A.C. 8:26-1 et seq). These regulations govern construction, safety, operations and water quality.
New Chlorine Stabilizer (Cyanuric Acid) Recommendations
The Centers for Disease Control has published in June 2015, a scientific article on the effect of chlorine stabilizer (Cyanuric Acid - CYA) on the inactivation by chlorine of the microorganism, Cryptosporidium. Based upon this article Garden State Labs, Inc. is recommending that if CYA is utilized, CYA be used at 10 parts per million (mg/l) and not exceed 20 ppm. If used, we recommend that CYA be tested weekly.

New Rapid Pool Testing Methods
Garden State Labs is using new bacteriological testing methods.
The New Jersey regulations require weekly testing for bacteria by a State Certified Laboratory and testing every two hours for pH and disinfectants (such as free chlorine or bromine) in swimming pools, whirlpools, spas and hot tubs. Lakes and beaches have to test for bacteria weekly. The bacterial tests are the standard plate count and total coliform in swimming pools, the standard plate count and Pseudomonas aeruginosa in whirlpools, spas and hot tubs, and fecal coliform in lakes and beaches.
The NJDEP is now requiring enterococci testing for ocean
beaches. The enterococci result shall not exceed 104 enterococci per 100
ml. In the future, E. coli may be used to replace fecal coliform in
some natural waters.
The State Regs also require that a Trained Pool Operator (TPO) be hired by all recreational bathing facilities to be responsible for maintenance and mechanical operations.
Federal OSHA regulations also require that lifeguards be trained to deal with potential exposures to blood and bloodborne pathogens.
With over 67 years of water testing experience we can help you with many types of water quality problems.
We are often asked about bacteria in water, what type of disinfectant to use and what are acceptable levels. You may email us with your questions and we will try to help. Please be as detailed as possible.
