Brown land restoration
What are the misunderstandings?
Myth 1: Contaminated site refers to contaminated soil.
Contaminated site refers to the site where soil and groundwater are polluted due to certain behaviors and activities, and the migration of pollutants will also pollute the soil and groundwater outside the site. Therefore, the remediation of most contaminated sites includes groundwater remediation.
Myth 2: The contaminated site is a brown field.
If the site is abandoned and its development and utilization are negatively affected by pollution, then this polluted site is also called brown land. Brown land is only a part of the polluted site, and its concept is imported, which has its specific meaning in foreign laws. In China, there are historical reasons for equating contaminated sites with brown fields. But now we should distinguish these two concepts from the perspective of development.
Myth 3: Contaminated sites refer to industrial contaminated sites, and closure and relocation will "produce" contaminated sites.
Industrial pollution is one of the reasons for polluting the site. Mining, commerce, military bases, recycling industry and waste management have also caused a large number of polluted sites. As the most polluted site, gas stations are not strictly industrial. The site is polluted because there are harmful substances, and the act of shutting down and moving itself cannot "produce" or "cause" the site to be polluted.
