4-19 Soil Washing FRTR

2020-7-30  Soil washing is a water-based process for scrubbing soils ex situ to remove contaminants. The process removes contaminants from soils in one of the followingtwo ways: By dissolving or suspending them in the wash solution (which can be sustained by chemical manipulation of pH for a period of time); or.

Ingesting soil. Though it might seem odd to eat soil, contaminants can be ingested in a variety of ways. If they come from contaminated soil, it’s important to wash them well, too. Breathing in contaminated dust may cause physical or chemical damage to humans. For example, asbestos fibers can puncture the lungs. Chemicals such as lead
