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.

In swimming pools and school pools, water quality testing is required to ensure that swimmers can use the pool comfortably and hygienically. Since many people use the pool at once, it is important to maintain the water conditions specified by water quality standards, and this needs to be confirmed through water quality testing. Additionally, to suppress the growth of bacteria, chlorine is commonly used as a disinfectant, which means that disinfection by-products (total trihalomethanes) are also subject to testing. For more details, please contact us or refer to the catalog.

Tap water is essential to our lives. The materials that supply tap water can be broadly classified into two categories: materials (equipment) used in the water purification process and transportation process at water facilities, and materials (water supply tools) that branch off from the distribution pipes installed by water service providers. "Leaching tests" are conducted to confirm whether harmful substances leach out from these materials when they come into contact with water. At Naito Environmental Management Co., Ltd., we prepare leachate from water supply materials and tools, and test whether this leachate meets the standard values for leaching criteria set by law. The analysis items and frequency may vary depending on the material differences, but please feel free to contact us if you have any questions. For more details, please inquire or refer to the catalog.

On June 13, 2018, a law amending part of the Food Sanitation Act and others was promulgated, institutionalizing hygiene management in accordance with HACCP. The "hygiene management based on HACCP" and "hygiene management incorporating the principles of HACCP" conducted by each food business operator include "management of water used" as part of general hygiene management. The use of water that does not meet water quality standards may lead to contamination by foreign substances or food poisoning. Food business operators implementing "hygiene management incorporating the principles of HACCP" will conduct hygiene management based on guidelines created by various industry organizations. This time, we have created an introduction to a set of inspection items for used water based on the guidelines prepared for supermarkets. ◎ Please download and view from the "PDF Download" link below.

Legionella bacteria, when they infect humans, cause an infectious disease known as Legionnaires' disease. In nature, they are found in small amounts in soil and freshwater, but the likelihood of direct infection from these sources is almost nonexistent. However, conditions in places like baths and cooling towers are conducive to the proliferation of Legionella bacteria, so even a small aerosol (water spray) can contain a large number of Legionella bacteria, which can lead to infection when inhaled. Legionnaires' disease is an infection that occurs when aerosols contaminated with Legionella bacteria are inhaled into the body. Its symptoms can be broadly categorized into Legionella pneumonia and Pontiac fever, which is a febrile illness similar to influenza. Additionally, there have been reports of rare symptoms such as inflammation due to skin contact. Special caution is needed for the elderly, patients, and infants who have inherently low immunity. Legionnaires' disease is classified as a Category IV infectious disease under the Infectious Disease Control Law, and physicians who diagnose it are required to report it immediately to the health department.

The safety of tap water is gaining attention. Water supply is an essential part of human life. The Water Supply Act establishes water quality standards to ensure "clean water" and maintain safety. Our company has obtained ISO 17025 certification and has set up a system to conduct inspections of the water quality standards specified in the Water Supply Act (51 items) with a short turnaround time (3 to 5 days). Additionally, when results exceed the standard values, we will notify you via email, and you can also check the progress of inspections on our website. *For more details, please contact us. *Various materials can be checked via PDF download.

PFOS and PFOA, which are subject to regulations both domestically and internationally, have also been detected in domestic drinking water, groundwater, and river water. Therefore, in 2020, they were established as items for setting water quality management targets under the Water Supply Act and as environmental standards related to the protection of human health from water pollution (items to be monitored). Our company is equipped to handle both testing methods and product analysis.

The international standard for the management of dialysis water (ISO 13959) specifies 22 items related to chemical contaminants as management items. In Japan, the Japan Society for Dialysis Therapy and the Japan Association of Clinical Engineers have presented the "Dialysate Water Quality Standards" as criteria for the management of dialysis water. According to the Dialysate Water Quality Standards, 12 out of the 22 chemical contaminants are designated as management targets, and they must be maintained below the management standard values (maximum concentrations) under the supervision of the Dialysis Equipment Safety Management Committee.

Legionella bacteria, when they infect humans, cause an infectious disease known as Legionnaires' disease. In nature, they are found in small amounts in soil and freshwater, but the likelihood of direct infection from these sources is almost nonexistent. However, conditions in bathtubs and cooling towers are conducive to the proliferation of Legionella bacteria, so even a small aerosol (water spray) can contain a large number of Legionella bacteria, which can lead to infection when inhaled. Legionnaires' disease is an infection caused by inhaling aerosols contaminated with Legionella bacteria. Its symptoms can be broadly categorized into Legionella pneumonia and febrile illnesses resembling influenza. Individuals with weakened immune systems, such as the elderly, the sick, and infants, are at higher risk of developing the disease, so facilities used by these populations require higher hygiene management compared to other buildings. Additionally, measures against Legionella are important due to their growth characteristics, making the removal and prevention of biofilm formation crucial.

PCBs were mainly used in insulating oils for electrical equipment, but it was found to be toxic, leading to a ban on its manufacture and use. According to the PCB Special Measures Law, businesses that own insulating oils, electrical equipment, and products containing PCBs are obligated to responsibly dispose of them or commission their disposal. The disposal deadline for low concentrations is until March 31, 2027, while the deadline for high concentrations is shorter and varies by region and product use. As the disposal deadline approaches, we encourage you to consider PCB analysis as soon as possible. Our company offers various PCB analysis services. Please feel free to consult with us.
