Recently more concern about multiple contaminated sites have been evolved. As most of the abandoned sites are contaminated with both organic and inorganic contaminants which are highly toxic to ecosystem. Different remediation methods (physical, chemical, and biological) have been applied on either organic or inorganic contaminants remediation but not appropiate for multiple contaminant remediation therefore the question arises is what could be the possible methods for multiple contaminated sites remediation?
Dear Beenish,
Phytoremediation is a soil remediation technology based on the natural abilities of plants to purify their substrate of contaminants found there. This approach has several advantages over conventional methods used in contaminated land management. Unlike the latter, it rarely involves excavation and soil transport, which greatly contributes to its low environmental impact and affordability. These economic and environmental benefits add to the aesthetic and ecological character of plant systems used in phytoremediation. In a context of multiple contamination, it makes sense to assemble different species in order to obtain a complementary set of remediation skills that will be adapted to the targeted site.

Well,
It is very difficult to conduct one method for treating different pollutants at once, as the type of pollutants is determined, for the purpose of determining the effective field remediation method.

Bioremediation is also an option. Even though it has it's disadvantages, if it well carried out, it can help in remediating contaminated points
Dear @Beenish Roha,
You have become aware of physical chemical and micro biological contaminants and an idea on how phyto remediation is possible for all of them using trees plants and sub mrged plants too.
There are a different forms of contaminants at project-sites on elements of Environment, Social and Economic growth affected in communities.
These three elements and their associated effects also would have to be remedied.
Well wishes.
The sequential cleanup is performed in full scale (field application) over 20 years. It employs so called "treatment trains" of remediation techniques. Sequential treatment is common practice in Europe and North America at least long time. The results of treatment of "multipollutant" contaminated sites are very good having high pollutant´s removal efficiency. It was proved that sequential treatment using various treatment techniques is an efficient and economic way of remediation of contaminated sites.
Phytoremediation could be applied at sites, where time required for remediation is not an issue.
Best regards
