The installer of a simple dedicated water supply is required to undergo a regular inspection once a year to confirm the management status of the simple dedicated water supply, based on the Water Supply Act, by a registered organization of the Minister of Health, Labour and Welfare. It is registered as a "Water Supply Act Article 34 Simple Dedicated Water Supply Management Inspection Organization" and conducts inspections ranging from external appearance checks of the facility to water quality tests at the water supply taps and document inspections.

In response to the revision of JIS S 3201 (Testing Methods for Household Water Purifiers) in 2010, we conduct filtration flow rate tests, removal performance tests, and filtration capacity tests. Additionally, we carry out RO water purifier tests and water shower tests based on the standards of the Water Purifier Association (JWPAS) and the Japan Water Works Association (JWWA), from planning to analysis. We use RO membrane permeate water for the test water, allowing us to conduct tests with stable water quality.

In September 2006, the Industrial Safety and Health Act was amended, reducing the asbestos content threshold from 1% to 0.1%. Additionally, in February 2008, a notification from the Ministry of Health, Labour and Welfare expanded the types of asbestos to six (chrysotile, amosite, crocidolite, tremolite, actinolite, and anthophyllite). We are quickly responding to the changing regulations and the latest analytical methods to conduct qualitative and quantitative analysis of asbestos.

We will conduct soil contamination surveys and analyses based on the Soil Contamination Countermeasures Act. In April 2010, the Soil Contamination Countermeasures Act was amended, requiring notification to the prefectural governor when changing the land characteristics of 3,000 square meters or more, thereby expanding the scope of regulation. We will assist in understanding the risks of soil contamination in environmental management systems (ISO 14001) at business sites and during real estate transactions.

Based on the Soil Contamination Countermeasures Act, we will classify whether there is a possibility of soil contamination through an investigation of the land use history and other factors. We will assess the potential for soil contamination based on the collection of materials such as property registration certificates and aerial photographs, and evaluate it in the report.

Groundwater quality standards have been established based on the provisions of Article 16 of the Basic Environmental Law, concerning the pollution of groundwater. Analyses of vinyl chloride monomer, 1,4-dioxane, and 1,2-dichloroethylene, which were added to the environmental standards in November 2009, are also being conducted. Additionally, we are conducting total petroleum hydrocarbons (TPH) analysis using GC-FID based on the "Oil Pollution Countermeasures Guidelines" published by the Ministry of the Environment in March 2006.
