For the construction of "Innovation & Communication Center" at Kawasaki Head Office, which was completed in June 2019, we conducted a soil survey based on the Soil Contamination Countermeasure Act and the Ordinance related to Conservation of Living Environment such as Kawasaki City Pollution Prevention. As a result of collecting and analyzing the soil of 136 blocks with area of 10m x 10m as one block, we found noncompliance in 50 blocks and the Class 1 Designated Hazardous Substances exceeding the groundwater environment standard at 14 spots as for the groundwater. We reported the result of the soil investigation of Class 1, Class 2 and Class 3 Designated Hazardous Substances and the groundwater investigation to Kawasaki City.

In addition, for one block where the Class 1 Specified Hazardous Substance exceeds the wastewater standard, we cleared the standard value by purifying by the biotechnological method and completed the report to the local government. Monitoring is conducted four times a year starting in November 2019.

We will continue to implement the observation and monitor at the observation well.

To prevent pollution by chemical substance, the procedure to prevent the diffusion at the time of leakage is checked periodically. Also, the equipment using polychlorinated biphenyl which was used in the factory premises in the past and the parts containing polychlorinated biphenyl used for the collected products are stored properly in the special storage warehouse of the head office until destruction treatment is carried out.
