The word "phytoremediation" is from the Greek prefix phyto- meaning "plant" and the Latin root word remidium- meaning "to correct or remove an evil". In soil, the "evil" could be anthropogenic (man-made) contaminants such as organic solvents, heavy metals, pesticides, or radionuclides.

Phytoremediation Advantages:

• Phytoremediation costs are much less than traditional in situ and ex situ processes
• Plants can be easily monitored to ensure proper growth
• It is the least destructive method of remediation because it utilizes natural organisms and solar power via photosynthesis
