Surveys of soil contamination completed at all sites
(Ricoh Group/Global)

If soil or underground water contamination goes unnoticed, it could affect the health of people in the neighborhood. Because of this, the Ricoh Group has worked hard to survey and purify major production sites since the 1990s, from the two viewpoints of corporate social responsibility and environmental risk management. The Ricoh Group has established Basic Policies Concerning Soil and Underground Water Contamination in the Standards for the Management of Risks Related to Soil and Underground Water Contamination. According to the policies, the Group started surveying the history of all Group business sites—including both the production and non-production sites of subsidiaries of Ricoh's subsidiaries— in fiscal 2004, and this was completed in fiscal 2006. At present, efforts are being made for the maintenance and improvement of management of soil and underground water contamination risks while surveys of new business sectors acquired by Ricoh through M&A, etc. are being promoted.

Ricoh Group's Basic Policies Concerning Soil and Underground Water Contamination
(1)	Top priority is given to controlling impact on the living environment in the neighborhood.
(2)	Efforts will be made to carry out surveys and measures to cope with contamination caused by the Ricoh Group's business activities.
(3)	Laws, regulations, and ordinances set by national and local governments shall be observed.
(4)	Efforts will be made to establish risk communication with local governments and residents.
(5)	Soil is checked for contamination when land is purchased/transferred or rented/returned.

Detection of contamination of underground water
(Ena Plant of Ricoh Elemex Corporation/Japan)

A new well for pumping water was installed in the process of purifying contaminated soil and underground water at the Ena Plant of Ricoh Elemex Corporation in July 2007, and analyses were carried out. As a result of the analyses, carbon tetrachloride, a toxic substance, of up to 0.051 mg/l (25.5 times higher than the environmental standard value of 0.002 mg/l) was detected in the underground water near the borderline of the site, although the Ena Plant has never used carbon tetrachloride. We carried out a close resurvey of underground water and soil gas at the business site during the period from the detection of contamination to March 2008, but could not specify the source of contamination. We will continue to check for contamination by analyzing the quality of the water in the well, as well as purification work.
