Soil and Groundwater purification technology

Purification technology of soil and groundwater：
We offer total support from investigation analysis to construction and monitoring.

Business Development

In recent years, the number of cases in which the ground is polluted by various toxic substances has been increasing. The contamination beyond the self-purification capacity of the earth will be passed to the future as a negative legacy.

We regard contamination of soil and groundwater as an important problem. As the total engineering service provider, we approach this problem from the customer’s perspective, proposing a consistent system service from investigation and analysis to purification and monitoring.
