The study was carried out to evaluate the quality of soil at the finished landfill located in Cai Dau town, Chau Phu district, An Giang province, Vietnam. Twelve soil samples were collected including 6 samples in the surface layer (0-20 cm) (namely S1-S6), 6 samples in the subsurface layer (60 - 80 cm) (namely S1-S6) for the analysis of heavy metals such as Fe, Mn, Cu, Pb, Ni, Cr, Zn.  The analytical results showed that all the heavy metals occurred in soil in which Fe was the highest and Ni was the lowest. The concentrations of the heavy metals in the soil surrounding the closed landfill in both layers were in the descending order of Fe> Mn> Zn> Cr> Cu> Pb> Ni. These heavy metals concentrations were within the allowable range of QCVN 03: MT/BTNMT- agricultural land. The occurrence of heavy metals in different layers at the surrounding landfill could potentially result in negative impact on the environments since heavy metals have the capability of accumulation. Therefore, monitoring of the environments around closed landfill should be implemented and the long-term risk of heavy metals should be estimated.
