Total Pollution Investigation of Soils
and Underground Water

Phase 1

Phase 2and Detailed(Conditions)
Investigation

Phase 3(Puriﬁcation)

Condition of pollutionof the land is investigated.

Based on the investigations
in Phase 1 and 2, contaminants are removed from thesoil and underground waterin the best suitable way.

・Investigation of theland usage in the past
①Old maps and aerial
photos②Acquisition of theland register③Interviews
・Investigation of theperipheral area
①Condition of underground water contamination②Geographical investigation, etc.

・Soil gas investigation
・Surface investigation
for heavy metals, etc.
・Surface investigation
for agricultural agent,etc.
・Boring investigation
・Underground water

・Reactive water retaining wall・Removal of soil bydigging, etc.

Investigation of Hazardous Chemical
Substances for Green Procurement
In order to manufacture an eco-friendly product, it is essential tomeasure the content of hazardous chemical substances containedin the parts and materials.
Based on the EU Directives of WEEE and RoHS, Fuji Denka provides analysis of hazardous chemical substances contained in anelectric and electronic apparatus and compliance to ELV.
Subject hazardous substances
・Cadmium ・Mercury ・Lead ・Hexavalent chromium
・PBB
・PBDE

Measures for Global
Warming Prevention

Possibility of pollutionof the land is investigated by examining
how it has been used.

Subject substances
・VOC (volatile organic compounds) ・Formaldehyde ・Toluene・Xylene ・Styrene ・Others

Investigation and Countermeasures against Soiland Underground Water Contaminations

Many buildings recently built such as houses and school buildings
are highly air-tight and heat-insulated to enhance living comfort
and energy-saving performances. However, this is partly a causeof sick house syndrome, which allegedly occur due to a certain
chemical substances emitted from building materials, interiormaterials and furniture.
Fuji Denka has long provided measurement of sick house inducing substances in rooms of newly built houses, flats and offices.
In order to respond to the needs of measuring those substances
emitted from office equipment and materials, Fuji Denka introduced in June 2005 a chamber-type VOC emission measuring andanalyzing equipment. This equipment has a chamber of 20ℓ and
1,000ℓ that can be applied to the size of the subject for measurement and VOCs emitted from IT equipment such as a personal
computer and home electrical appliances to furniture and officeautomation equipment can be measured using the measuringequipment.

Promotion of Environmental
Management

Fuji Denka was appointed as a designated research and investigation institute from the Minister of Environment in February 2003,
based on the Soil Contamination Measures Law under the license
number 2003-1-184. It provides an integrated research and investigation service from investigating the quality of soil and underground water including the concentration of volatile organiccompounds, heavy metals and agricultural agents to advisingassessments and measures against them, based on its abundant
experiences in this field. The assessment items covered include
Phase 1 to Phase 3 as shown in the table below.
