Designated Investigation Agency | Investigation to Prevent Chemical Substance Leaks from Aging Equipment | Geotech
Soil contamination survey
Early detection of potential soil contamination risks due to aging factory infrastructure! Comprehensive support from usage history investigation to soil gas analysis and accurate determination of contamination extent.
The aging of infrastructure facilities such as underground piping, drainage pits, and chemical storage tanks in long-operating chemical plants, manufacturing factories, or metal processing facilities poses a serious governance risk by causing the underground leakage of invisible harmful substances. This comprehensive investigation service is an environmental defense package designed to inventory potential contamination risks on-site early while maintaining daily operations and to avoid the negative legacy of land assets. First, in Phase 1, the usage history investigation thoroughly examines detailed documents such as past equipment layouts and repair records to accurately pinpoint areas with a high risk of leakage. In the subsequent Phase 2, overview sampling is conducted using methods that do not interfere with operations, employing high-precision soil gas analysis to detect trace amounts of volatile organic compound leaks and scientifically quantify the underground conditions. In the event that infiltration into the underground is detected, a detailed investigation will accurately determine the extent of contamination, assist in the formulation of annual planned purification and diffusion prevention measures, and completely eliminate the risk of future significant loss troubles.

basic information
This comprehensive survey is a specification for designated investigation agencies compliant with the Soil Contamination Countermeasures Act, optimized for infrastructure maintenance and risk management in operating factories. In Phase 1, a historical investigation will be conducted by meticulously examining the factory's equipment renewal ledger and drainage route diagrams, along with a utilization history survey. In Phase 2, a compact sampling device that does not interfere with the operating line will be deployed to conduct high-precision soil gas analysis for rapid detection of leaks from chlorine-based solvents and surface sampling of heavy metals. In Phase 3, additional drilling will be performed to precisely analyze the depth of contamination, and three-dimensional contamination map data indicating the minimum necessary remediation area will be delivered.

Applications/Examples of results
It is utilized for the voluntary inventory of environmental risks associated with the aging of equipment in factories and plants that have been in operation for many years, for contamination prevention audits on-site in preparation for disasters and accidents, and for confirming asset value in anticipation of future inter-family succession of the site or internal reorganization. By gradually advancing steps from historical analysis to soil gas analysis and determining the extent of contamination while maintaining continuous production, it prevents the deterioration into sudden large-scale contamination. It strengthens compliance with environmental regulations and is widely implemented in practice as an objective proof of social credibility to shareholders and neighboring residents, as well as design data for optimal preventive maintenance plans.
