Serious global problems could arise from excessive levels of heavy metals released into the environment as a result of sewage, chemical fertilizers, human activities, and non-biodegradable industrial wastes. With an emphasis on evaluating the sources of pollution and the possibility of phytoremediation using three perennial aquatic macrophytes (Eichhorniacrassipes L., Ludwigia stolonifera L., and Pistia stratiotes L.), this study examined the levels of heavy metal contamination in three drainage systems along Egypt's Nile Delta: Faraskour, El-Serw, and Hadous. Heavy metal concentrations such as iron (Fe), copper (Cu), lead (Pb), cadmium (Cd), cobalt (Co), manganese (Mn), nickel (Ni), and zinc (Zn) were measured in sediment, water, and plant samples. Additionally, two phytoremediation factors—bioaccumulation factor (BF) and translocation factor (TF)—were estimated for every plant. The findings showed that the three drains' sediment heavy-metal concentrations happened in the following order: El-serw > Faraskour > Hadous. The sediment heavy-metal concentrations in the three drains were roughly arranged as follows: Fe (0.86-0.89 mg kg-1) > Mn (0.7-0.65 mg kg-1) > Cu (0.4519-0.4522 mg kg-1) > Pb (0.21-0.22 mg kg-1) > Cd (28.39-59.21 mg kg-1) > Ni (25.6-32.67 mg kg-1) > Co (2.53-3.16 mg kg-1) > Zn (2.28-2.35 mg kg-1). For heavy metal phytoremediation, E. crassipes showed the most promise, particularly for Fe, Mn, Pb, Zn, Cu, Ni, and Co. For Cd, L. stolonifera was the most successful. The results highlight how phytoremediation may be used as a long-term way to reduce heavy metal pollution in drainage systems. It is advised that immediate action be taken to save Egypt's Nile Delta ecology, which includes building water treatment facilities and improving wastewater management techniques.
