How Simple Plants Can Help With Soil Remediation?

Just as in any soil remediation process, the first step was to sample and analyze the soil to create a contaminant profile. The results showed some areas affected by the flood-borne chemicals, but the soil also showed older traces of lead contamination.

Phytoremediation for natural soil remediation:

The use of plants and plant material to clean up soil is called phytoremediation. This is easily the preferred approach for any environmentally aware landowner. It is also quite surprising to realize how many types of contaminants can be safely removed from your land without disturbing the soil or using harsh chemicals. You can also look for the best soil remediation techniques online.

Going back to New Orleans today, one can see phytoremediation at work in some parts of the city. Led by Common Ground volunteers, these soil remediation efforts are using sunflowers to clean up lead from their soil. These popular plants are adding a dash of color to neighborhoods, all while their roots soak up the harmful lead from the soil.

As the sunflowers grow, they accumulate lead so care is taken that the seeds are not consumed by people. Once the plants are cut down and destroyed, fresh soil readings are taken to measure lead levels. The results so far are very promising; each crop of sunflowers leeches away a little more lead from the soil.
