 Eliminate the environmental and safety hazards they pose  Increase property values  Take advantage of underused land  Bring new jobs and more tax revenue into community  Eliminate “eyesores” or “blight”

 Bioremediation  In situ oxidation  Soil vapor extraction  Phytoremediation  Iron-curtain barrier
