Abstract

Pampa river is the third longest and one of the most stressed rivers in Kerala. Hence, many researches have been
done highlighting the pollution status of Pampa river. In this study, phytoremediation, the cost-effective and eco-
friendly technique was employed for the removal of contaminants from this river. By planting Vetiver zizanioides
for 6 months by hydroponic technique, the amount of lead, mercury, and most probable number of coliform was
found to be decreased by 100%. A large decrease of dye content was also noticed by this technique.
