Recovery of ecosystems pollution by contaminants of potential concern using phytoremediation techniques
AbstractPhytoremediation is a technology that uses plants to break down, remove, and immobilize contaminants in surface water, shallow groundwater, and sediment to achieve cost savings compared with conventional treatments. This study describes a marshy land on an explosives manufacturing site in India that consistently reported elevated concentrations of nitrates, nitrites, ammonia, perchlorate, and lead (contaminants of potential concern—CoPC). The study also illustrates the potential for addressing the human health and environmental risks associated with the explosives manufacturing industrsy in India using innovative, sustainable, and carbon‐neutral techniques. This work focuses on reconstructed marshy lands, desedimentation, microwatershed management, and phytoremediation using Phragmites and Vetiveria species (also known as vetiver) to reduce contaminants in surface water and groundwater, improve stormwater management and carbon capture, and increase natural capital like biodiversity. The results obtained during the trial indicate that the selected indigenous species are effective and can be used to remediate sediment and shallow groundwater for many CoPC in tropical climates.

KEY POINTS The results obtained during the trial indicate that the selected indigenous species are effective and can be used to remediate sediment and shallow groundwater for many CoPC in tropical climates. If we drew a life cycle based on this study, it would be as follows: contaminants deposited to nature (soil) are extracted by plants (natural, no chemical intervention), and as the plants uptake the contaminants, they are harvested and turned into compost, which can again return to the soil (nature). This approach can reduce contaminants in both sediment and water, and is a low‐cost and environmentally friendly remediation alternative to more traditional methods.
