Soil and Groundwater
Surveys and Measures Taken on Soil and Groundwater Contamination
Efforts regarding soil and groundwater contamination
Konica Minolta is striving to manage the state of contamination through regular monitoring, to facilitate cleanup, and to prevent the spread of contamination.
It conducts robust management through periodic observation at sites where soil or groundwater contamination has been identified in order to implement measures to ensure that the contaminants do not affect the surrounding environment.
The Group has organized a special team to manage remediation of polluted sites and to prevent the spread of contamination. Detailed surveys conducted under the team's supervision serve as the basis for developing countermeasures and examining suitable purification technologies.
The Group reports the results of its observations and remediation efforts to local government agencies.
