Impacts de l'utilisation d'eaux usées traitées par lagunage à macrophytes pour l'irrigation sur la qualité des sols et des eaux souterraines; cas du vétiver (Vetiveria zizanoides)

Matadi city inhabitants rely on septic tanks. Human excreta are directly discharged into rivers without pre-treatment. The same water is used to water vegetables, therefore spreading pathogens within the population. We have initiated the biological treatment of these wastewaters with Vetiveria zizanoides prior to their discharge into the natural rivers.
