We analyze and evaluate soil contamination by conducting various types of soil surveys.

• Land history surveys
• Soil contamination surveys
  (topsoil surveys and soil gas/boring surveys)
• Groundwater surveys

We provide optimal proposals based on conditions and survey data including treatability testing. We also perform administrative procedures and provide resident education.

• Risk assessments
• Treatability testing (determination of treatment methods)
• Administrative procedures
• Risk-related communication

Soil is washed using slurry agitation.
This system utilizes the concentration (screening) and wastewater treatment techniques developed by JFE Mineral.

This technique regulates the dissolution of heavy metals over extended periods of time using mineral additives.

Heavy machinery is used to excavate contaminated soil and then transport the soil for off-site treatment. This method enables complete removal of contaminated soil quickly.

Specialized iron powder is used to quickly decompose highly concentrated VOCs.
Because foam is used instead of water, this technique produces less sludge than traditional techniques.

Bio-nutrients are injected into the ground to decompose VOCs via microorganisms.

This material can adsorb heavy metals when added to sludge and contaminated soil.
Iron powder that has adsorbed heavy metals can be recovered via separation and centrifugation, and so this material is used to treat contaminated soil. Recovered iron powder can be reused repeatedly.

This material can insolubilize heavy metals when added to contaminated soil.
This material can keep the pH of treated soil from exceeding 10.5 to prevent soil from becoming highly alkaline.

This construction material used for heavy metal adsorption is a non-woven sheet that contains heavy metal adsorbing material.
When used as provisional material for contaminated soil, this product can help prevent the spread of contamination by efficiently adsorbing heavy metals from exuded water.
Because this product is mass-produced, the performance of the adsorption layer performance is consistently reliable.

This material can quickly decompose highly concentrated VOCs to environmental standards.
This material can be used in various methods such as soil mixing, purification walls, and the iron powder and foam method. It is also effective in purifying groundwater.

This bio-nutrient promotes activity of microorganisms that decompose VOCs in soil and groundwater.
This product is less expensive than conventional products such as polylactic acid, higher fatty acids, and amino acids.
This material is also harmless to humans, animals, and plants.
