The present investigation entitled "Eficiencia de fitorremediación de Pistia stratiotes y Eichornia crassipes en lixiviados generados en el botadero de Cuñumbuqui, San Martín 2020." It has as a general objective is to evaluate the efficiency of the phytoremediation of the selected species that are the Pistia stratiotes and Eichornia crassipes, this research is of an applied type since in the treatment, phytoremediation techniques were applied using macrophyte species under ex situ conditions; with a quasi - experimental design; The population corresponded to the leachate generated in the Cuñumbuqui dump, from which a sample of 130L was obtained, where 20L was distributed for each of the 6 ponds that were used in the treatment, which was carried out in a period After 15 days, the field parameters (pH, temperature, EC and DO) were monitored every 3 days during that time; Likewise, techniques and instruments were used to collect data, respectively, such as: the field record sheet, daily record, and chains of custody; The procedure was developed in stages both in the office for the systematization of information and data, and in the field to carry out the project. In conclusion, the application of macrophyte species in leachates formed in landfills is a treatment alternative, it was found that Eichhornia crassipes is more efficient than Pistia stratiotes, since it has a greater removal of pollutants to improve the quality of these waters, which that would allow giving it a different final disposition.
