Phytoremediation of the banks with native plants

Project summary

Edit project overview to modify the project summary.

This phytoremediation project aims to rehabilitate 100 m of the riverbanks in the Matanza-Riachuelo river which was characterized in 2013 by Green Cross Switzerland as one of the ten most polluted sites in the World. Nowadays, the river basin is subjected to different types of contaminants from agricultural and urban runoff, industrial effluents, sewage treatment plants and leaching from domestic garbage dumps. Through the enhancement of native vegetation with high phytoremediation capability the project aims to improve 1) the quality of life of the urban residents through the revitalization of public space; 2) the environmental recovery in all its components (water, air and soil).

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

Up to date metals contents in soil, roots and leaves of the implanted herbs and trees are being monitored to evaluate the remediation capacity.
