Answer:

1) soil vapor extraction

-------Air is circulated through perforated pipes in the contaminated soil.

2) air sparging--------- Air is bubbled through groundwater to remove volatile organic pollutants.

3) bioventing ----- Air is pumped into or out of soil to supply oxygen to microbes.

4) natural attenuation------ Natural processes break down the pollutants.

Step-by-step explanation:

Soil vapor extraction is a method in which air is circulated through perforated pipes in the contaminated soil for the cleaning of soil from pollutants. Air sparging is a remediation technique in which air is bubbled through groundwater to remove volatile organic pollutants present in water bodies. Bioventing is a process in which air is pumped into or out of soil to supply oxygen to microbes which helps in the decomposition process. Natural attenuation is a natural processes which helps in break down the pollutants present in the soil.
