In June 2006, an abnormal discharge of water was found when renovating facilities at Aisin Seiki's Nishio Plant. When the soil was analyzed and surveyed, it was discovered that levels of hexavalent chromium and cyanide compounds in part of the soil exceeded environmental standards.
Aisin Seiki acted in accordance with guidance from Aichi Prefecture and other relevant authorities to swiftly implement purification measures after a more detailed survey of the site. We also offered briefings and 2,000 liters of drinking water to local residents until safety could be confirmed. After a thorough survey, it was confirmed the well water was not contaminated.
Regarding our facilities, in addition to purification of the contaminated soil, we quickly took preventive measures such as increasing the number of pumping wells in order to reinforce purification treatment capabilities for contaminated groundwater.

To promote the introduction of wastewater treatment facilities, AISIN installed a new circulating system that meets its stringent environmental standards and employs the treated water in the plant's cogeneration system (20% reduction).
