Abstract

The appearance of some metals such as Fe, Al, As and other compounds with artificial origin as Zn, Cu, Pb in groundwater has become issues and being interested to many researchers. In the area of water supply, the problem of metal pollution from some water supply companies and households not only appears in surface water but also in groundwater, which reflected in the metal contamination over permissible standards and seasonal oscillations. In this study, a survey of current pollution was carried out to elucidate the distribution of some metal ions such as total iron, Al3+, As5+, Cu2+, Pb2+ and Zn2+ in groundwater in Go Vap District. The results showed that these metals are distributed mainly at mid-upper Pleistocene aquifer (qp2-3) from 8 meters to over 40 meters and in strongly to moderately acidic environment, which have pH from 4.2 to 5.0. As results, this study shows that these metals in groundwater related to the origin and sediments composition of permeable and impermeable aquifers. In addition, the metal pollution such as Cu2+, Pb2+ and Zn2+ in recent years may be due to the artificial origin.
