The GEPC accurately investigates, analyzes, and evaluates the state of contaminated sites and their impact on surrounding areas, and conducts studies on countermeasure techniques, control methods, and re-use of treated soil in order to offer the most efficient and economical measures.

The GEPC cooperates with a number of research institutes both in Japan and overseas, and participates in international conferences, and uses the information, findings, and materials obtained from these activities to form appropriate systems and site investigation and remediation techniques in Japan.

The GEPC holds study meetings, seminars, and lecture meetings for the purpose of disseminating knowledge and techniques on soil and groundwater contamination. The GEPC also publishes reports that introduce the above activities and their outcomes, as well as a mail magazine.

The GEPC carries out the following work of granting qualifications to engineers and managers to help improve the reliability of soil and groundwater contamination investigations and remediation work.

This qualification is granted to reliable senior engineers who have appropriate knowledge and judgment ability with respect to performing investigation and remediation of soil and groundwater contamination.

This qualification is granted to reliable engineers who have the required skills for (1) Work safety, (2) Consideration for the environment (e.g., preventing dispersion of contamination), and (3) Quality control (ensuring the quality of field work).

This qualification is granted to land managers who have basic knowledge for determining the state of contamination around a factory site in order to prevent soil and groundwater contamination and maintain and improve the asset value of land.

At the request of the Japan Environment Association, which is the designated support corporation in the Soil Contamination Countermeasures Act, the GEPC provides a Control Manifest of contaminated soil for transport or processing to which contributions are added.
