4 Main Ways of Clean up4 Main Ways of Clean up
Excavation- “Dig it all up and take away”Excavation- “Dig it all up and take away” Incineration- “Dig it up and burn baby Incineration- “Dig it up and burn baby
burn”burn” Containment- “Trap it and remove it”Containment- “Trap it and remove it” Electrification- “Zap it to oblivion” Electrification- “Zap it to oblivion”
