The macrophyte plants such us Eichhornia crassipes y Pistia stratiotes, as heavy metal purifier in domestic wastewater of Shilcayo River. Among the important problems that the receiving bodies are exposed to today is contamination by heavy metals, which leads to a decrease in their environmental quality, added to the populations that are located in areas, and consequently an incorrect discharging of wastewater to the rivers; for this reason, the objective of this research was to evaluate the efficiency of the use of the mocrophyte plants such as Eichhornia crassipes y Pistia stratiotes to purify heavy metals in domestic wastewater of Shilcayo River. The study scope was La Banda de Shilcayo district, having 120 L of wastewater representative sample from the river and 72 macrophyte plants. The completion period was 6 months. Three treatments were considered, 5, 10 and 15 days for each of the macrophytes used in the study, and a control sample. The applied design was experimental. The results found in the control sample were 0.010 mg/L for lead, 0.00046 mg/L for cadmium and 0.030 mg/L for arsenic, in which only the As comply with what is established by the ECA-Agua, 15 days after the treatment, the highest efficiency of contaminants removal was achieved, for Pistia stratiotes with 96.33% removal for arsenic and with 96% removal efficiency of the same pollutant for Eichhornia crassipes, which do not exceed what is established in category 4: conservation of aquatic environments, E2: Rivers of the jungle, from the ECA, getting a significant statistical difference level of 95% for lead and arsenic removal, in treatments that were carried out. The research concludes that the highest removal efficiency of contaminants occurs when treating T3, with 0.002 mg/L for lead in 15 days of experimentation and 0.00025 mg/L for cadmium, both of them with the Eichhornia crassipes, getting that both results fulfil what is established in the ECA-agua.
