Douglas:
When it comes to environmental treatment, there are several
technologies that are out there but because of my professional
occupation, I am not too familiar or aware of what they are. So
to educate me, I will do some research and who knows maybe I
will find one that I am aware of. There are 5 green technologies
that are used for environmental remediation to help remove
pollution, contamination, and exposure to radiation. These
contaminations can be found in groundwater, soil, sediments, or
rocks but can be undone by putting human intervention in place.
· The first green technology used is
Thermal Desorption
which uses a heat process at different melting points of
substance that removed the contaminants from the soil, sludge,
or filter cake and uses it. Do not get this confused with the
incineration process which heats the contaminated material to a
point it destroys it.
· The next one is Surfactant
Enhanced Aquifer Remediation (SEAR)
but better known as solubilization and recovery which injects a
chemical solution across the contaminated areas then pumps out

2. the waste at an extraction point. The primary goal of using this
process is to remove the maximum amount of contamination by
using small amounts of chemical being pumped while
using hydraulic control to help diffuse the waste and chemical.
· The third technology is
In situ Oxidation
which takes the toxins inside the contaminants when turns them
into less harmful or toxic. This process can be used to treat
groundwater and soil contaminates with a pump and treat
method to help clean up the contaminants.
· The fourth technology uses
Soil Vapor Extraction and Air Purging
this is a physical process that takes the unsaturated state of the
contaminate such as vapor from the below groundwater to the
surface by applying a vacuum while air purging pushing the
contaminate below the water table.
· The final technology used for environmental treatment is
Nanoremediation (In situ Oxidation)
which is the future for all technologies which is found in
medical processes, computing, and various other fields. This
process has already been used in groundwater treatments as well
as extensive testing and research for wastewater treatments and
sediment cleanups.
These are all good technologies to treat the environment but I
see some issues with them especially when it comes to funding
them. Now when it comes to environmental remediation they
are usually funded by government or other related authorities.
The biggest issue is groundwater and surface pollution which
cause a major health risk to human populations but these
remediation processes pose an incremental health risk as well.
Thermal Desorption is an excellent engineering way to handle
contaminants in solid masses but when the clean vapors are

3. released, there is still a chance that toxins can enter the
atmosphere so there needs to be some type of monitoring in
place to ensure this does not happen. The only issue I see when
using the chemical oxidation is that there could not be enough
heat to cause the contaminants to evaporate and be left behind
in the soil which will find its way into the groundwater and
cause health issues for the surrounding human population.
Before placing environmental technologies in place, it is
engineers that need to do their homework to ensure that all
bases are covered to protect human health and the environment.
By testing the present and future technologies to ensure they
work as designed in small areas is a sure way to reduce the
likelihood of a failure and lead to an environmental disaster.
