Water quality analysis: Hygiene and water quality management of bathwater.

The inspection items for public bathhouses are established by ordinances in each prefecture, and there is no uniform standard nationwide. Please contact us for the necessary inspection items.

In "public baths" used by an unspecified large number of people, water quality testing items and their frequency are established as indicators of hygiene management. Particularly, due to the high risk of bath water entering the mouth, appropriate hygiene management is required. Among the testing items, "Legionella bacteria," which can cause infectious diseases, is considered the most important. Additionally, regular cleaning and disinfection of the bathtub and plumbing alone make it difficult to determine whether hygienic management is being maintained, so verification through water quality testing is necessary. Given that many of the sources of the rapidly increasing cases of Legionnaires' disease in recent years are from hot springs, public bathing facilities, and 24-hour baths, regular testing is recommended.
