Contaminated Soil Remediation
Common soil contaminants can be of biological nature (bacteria, viruses), heavy metals, organic industrial pollutants (such as petroleum products, herbicides, insecticides), acids, bases, volatile organic compounds, radio-nuclides or solvents.
Soil treatment technologies include:
1. Chemical neutralization - using chemicals such as CaOH2 or Sodium Bi Sulphate to adjust the pH of the soil
2. Using oxidizing agents to oxidize POP's (persistant organic pollutants)
4. Bioremediation - using bacterial cultures to break down the pollutants
6. Heating of soil
7. Pump and treat systems
9. Soil washing
