Public Pool Water Testing per the Ministry of Health
Which parameters are tested in a pool, how often sampling is done and the requirements for opening the bathing season.
Read MoreA public mikveh combines a halachic requirement for a reservoir of rainwater with a health requirement for water that is safe for immersion. Periodic water testing makes sure the mikveh meets the Ministry of Health's guidelines and protects the health of those who immerse, without compromising the mikveh's kashrut.
Why Mikveh Testing Is Required
Because of how it is used - a large volume of water, many bathers and a temperature that suits bacteria - a mikveh is an environment that demands ongoing monitoring. Testing the water confirms that the filtration and disinfection system is working and that water quality is maintained over time.
What Is Tested
- Total bacteria count to assess water quality.
- Coliform and E. coli bacteria as an indicator of contamination.
- Pseudomonas aeruginosa, common in hot-water systems.
- Operational values such as disinfectant level and acidity (pH).
Balancing Halacha and Health
Mikveh testing calls for an understanding of how the mikveh operates in order to sample correctly and preserve its kashrut. We coordinate the sampling with the mikveh operator so that the health test is carried out without compromising the halachic requirements.
Frequency and Documentation
Sampling frequency is set according to the Ministry of Health's guidelines and how heavily the mikveh is used. Orderly documentation of test results makes it possible to track water quality and to demonstrate compliance during an inspection. The Kesar Digum team samples the mikveh water and delivers the samples for testing at an accredited laboratory, nationwide.
