The aim of this paper is to assess the environmental risks associated with the wastewater reuse with respect to six metals; cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) in the city of Dubai. Treated Sewage Effluent (TSE) is used for landscape irrigation. Samples of soil and control soil as baseline measurement were collected to calculate the contamination factor (CF), pollution load index (PLI), metal pollution index (MPI), degree of contamination (CD) and modified degree of contamination (mCD) of heavy metals in soil. The results revealed that the values of the CF were very high, the PLI and MPI were high, the CD was very high, the mCD was ultra-high.
