Preventing Soil and Groundwater Pollution
Fujitsu conducts soil and groundwater contamination surveys, implements countermeasures, and discloses the resulting data.
Our Approach
We review as necessary our internal rules established in FY 2006 in response to soil and groundwater problems, and will handle such problems based on these revised rules for soil and groundwater surveys, policies, and disclosure. In the future, in parallel with performing planned surveys and, if contamination is discovered, implementing cleanup operations and countermeasures appropriate for the conditions at each business site, we will also disclose relevant information in collaboration with administrative agency.
Status of New Soil and Groundwater Pollution Measures Undertaken in FY 2012
A voluntary survey in FY 2012 revealed soil and groundwater contamination at two sites. We reported the state of contamination at this site and explained our countermeasures to administrative agency.
Measures to Clean Up Soil and Groundwater Pollution Due to Past Business Activities
We have dug wells to monitor groundwater contamination near our sites where soil or groundwater pollution has been found. We continuously monitored eight such sites in FY 2012.
The table below lists the largest of the most recent measurements for chemicals with levels recognized to have exceeded regulated levels in FY 2012 stemming from past business activities.
