Each contaminated site requires different remediation efforts. The remediation technique you use should be based on the type, extent, and concentration of contamination, as well as the risk level. Some examples of remediation techniques are: 

• Pump-and-treat, a process in which contaminated groundwater is brought up from the subsurface for treatment.
• In situ remediation, which involves placing injection wells in the natural path of groundwater for treatment of contaminants.
• Phytoremediation, which involves planting the site with plants that uptake and store contamination within the plant tissue.      
• Haul-away, where the contaminated soil is removed from the site and used as daily cover at the landfill.
