List of land related to soil pollution

Land that does not conform to the designated standards stipulated in the law or ordinance and is found to be contaminated with soil, it will be designated as one of the areas depending on whether the trigger of the soil survey is the law or ordinance. The following information is listed in a list.

This refers to an area where soil contamination has been recognized, and measures such as removal of contamination are required because there is a route for intake of soil contamination to people and cause health hazards.

This refers to an area where soil contamination has been recognized, and there is no risk of causing health damage, so measures such as removal of contamination are not required because there is no route for intake of soil contamination to humans.

After judging the applicability of the standards for the risk of health hazards, such as the use of surrounding groundwater, it is designated as either the required area (laws and ordinances) or the required notification area at the time of trait change.
