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 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.
| Operation Site | Substances | Progress in Fiscal 2019 |
|---|---|---|
| Tokyo Site Hino (Hino, Tokyo) |
Fluorine, Boron, Mercury, Benzene, Lead | The company has continued to periodically monitor groundwater at the site boundary and has confirmed that amounts of these substances do not exceed standards. |
| Tokyo Site Hachioji (Hachioji, Tokyo) |
Hexavalent chromium | The company has continued to purify groundwater and prevent dispersion by pumping water at the site. It has periodically monitored the groundwater and confirmed that there is no runoff of these substances from the site. |
| Kofu Site (Chuo, Yamanashi Prefecture) |
Fluorine | The company has continued to periodically monitor groundwater at the site boundary and has confirmed that amounts of fluorine do not exceed standards. |
| Mikawa Site, Western Zone (Toyokawa, Aichi Prefecture) |
TCE*1, Fluorine | With the construction of a new plant, the company purified soil that exceeded standards for lead. It also carried out purification work for fluorine in fiscal 2018, and is periodically monitoring groundwater for a period of two years to confirm the effects. It has continued to periodically monitor groundwater for TCE, and has confirmed that amounts of this substance do not exceed standards. |
| Itami Site (Itami, Hyogo Prefecture) |
Lead, Arsenic, Cadmium, Fluorine, Boron | The company has confirmed that amounts of lead and cadmium do not exceed standards at periodically monitored wells. It continues to purify and prevent dispersion of other substances by pumping up water at the site. |
| Sakai Site (Sakai, Osaka) |
TCE, PCE*2, c-DCE*3, Boron, Lead, Arsenic, Cadmium | The company has found that amounts of lead, arsenic, and cadmium do not exceed standards at periodically monitored wells. It continues to purify and prevent dispersion of other substances by pumping up water at the site. |
| Osaka Sayama Site (Osaka Sayama, Osaka) |
TCE, PCE, c-DCE | A survey of the demolition plan for old buildings found soil and groundwater exceeding the standards. The company will continue to take additional measures besides pumping up water at the site to purify and prevent dispersion. |
| Konica Minolta Mechatronics Co., Ltd. Ueta Plant (Toyohashi, Aichi Prefecture) |
TCE, c-DCE, Hexavalent Chromium | The company has continued to purify and prevent dispersion of groundwater by pumping water at the site. |
