remediation

The process of cleaning up environmentally contaminated sites. It may be active, which requires some human intervention,or it may be passive and accomplished through the normal processes of nature. It may be ex situ, in which contaminated material is removed, or in situ, which relies on cleaning mechanisms in place on the property. Processes can include mechanical, chemical, thermal, magnetic separation, manual separation, use of biologic agents, or flushing, to name a few.
