Sustainable Phytoremediation Strategies for River Water Rejuvenation

Abstract Rapid urban growth and industrial insurgency contaminate aquatic ecosystems severely. River water, the greatest source of drinking water, becomes polluted in India, e.g., due to the discharge of three quarters of the untreated sewage generated, which leads to various water-borne diseases in humans. This chapter gives insight into the sustainable wastewater remediation technology of constructed wetlands to mitigate onsite pollution at ground level. This cost-effective, green technology of waste reclamation makes the rejuvenation of aquatic systems, like rivers, lakes, and streams, etc., possible. In addition, it also provides a habitat for the growth and expansion of the biodiversity of plants and animals.
