Soil
contamination is a problem that has many possible solutions. The issue being that it is difficult to jump
start these solutions in order to help gain control over the pollution and
contamination of soil across the planet.
So, what are some possible solutions to this issue?
According
to the United States Environmental Protection Agency, there are three general
ways to go about cleaning up soil that is contaminated and/or polluted. The first is that soil can be excavated from
the ground and be treated or disposed. The
second approach is that soil can be left in the ground and treated in
place. The third approach is that soil
can be left in the ground and contained to prevent the contamination from
becoming more widespread and reaching plants, animals, or humans.
How
do you go about containing this soil?
Generally, containment of soil (in place) is done by placing a large
plastic cover over the soil to prevent direct contact and keep rain water from
seeping into the soil and spreading the contamination. How can we work on treating the contaminated
and polluted soil? One option is by
flushing contaminants out of the soil using water, chemical solvents, or
air. Another possibility would be to
destroy the contaminants by incinerations.
We could also encourage natural organisms in the soil to break them down
or add material to the soil to encapsulate the contaminants and prevent them
from spreading.
As
you can see, there are many different routes that can be taken when dealing
with the prevention and/or treatment of contaminated and polluted soil. In my eyes, the main issue with these is that
it is costly and time consuming. With so
much soil across the planet being contaminated over time, it is becoming
increasingly difficult to contain the problem.
It’s important that we begin to implement and carry out these measures
to restore healthy soil.
