Designated Investigation Agency | Regional Historical Survey to Prevent Secondary Contamination from Land Use Change of Former Factory Sites
Geological and historical survey
Completely eliminate secondary pollution and conflicts with local residents caused by large-scale urban redevelopment! A historical investigation of land use change for factory sites to protect area value.
In an urban redevelopment project that transforms a vast factory site into a residential area, ensuring the overall safety of the community and achieving sustainable area management is an extremely important administrative and social responsibility. Ignoring the presence of harmful substances associated with past operations while carrying out large-scale land alterations and infrastructure development can lead to widespread risks of contamination spreading to surrounding residential areas and groundwater systems, potentially creating serious conflicts with the local community. This catalog comprehensively covers the entire process of "historical land use verification" to completely control such secondary contamination risks from both technical and legal perspectives. It explains advanced geotechnical historical investigation methods that digitally overlay old maps and chronological aerial photographs, tracking the changes in land reclamation and embankment that once existed, as well as the history of surface elevation. Furthermore, it details the practical implementation of official sampling surveys to fully comply with unique municipal environmental standards and soil disposal regulations, along with the establishment procedures for a solid safety certification for residents that can be directly used in community explanations, making it an essential resource for creating clean urban environments.

basic information
This is a soil self-investigation service for large-scale development provided by Geotech, a designated investigation agency, based on the Ministry of the Environment's guidelines and the unique environmental and soil regulations of local governments. In the phase 1 historical investigation related to land use change, in addition to analyzing public notification documents, we digitally analyze historical maps and aerial photographs over time to meticulously track and evaluate past land reclamation and land alteration, as well as large-scale embankment history on a grid basis. Furthermore, in areas with a high likelihood of contamination, we conduct phase 2 sampling investigations and component analysis fully compliant with official methods, precisely quantifying the leaching and content of 26 specific hazardous substances. We prepare neutral and highly reliable measurement reports that can be directly used for notifications to local governments and as disclosure materials for residents.
