Abstract

Ben Tre province is located in the lower delta-plain of the Mekong River Delta, southern Vietnam surrounded by the Tien River system and 65 km long coastline on East Sea. Tropical monsoon climate characterized by high annual rainfall of 1,250 - 1,500 mm and high average annual temperature which are favorable for agricultural cultivation. In the dry season, due to the long coastline and large river mouths, saltwater intrusion appears seriously, greatly affecting cultivation and people's lives in rural areas, especially drought and saltwater intrusion are more serious in the recent years due to the effect of climate change. Research on the use of shallow groundwater for living use and crop irrigation, contributing to agricultural development in drought and salinity conditions. On the base of available research data, 8 geological boreholes and 6 hydrogeological boreholes were carried out in this study. The research results have determined characteristics of sediment from the cores and distributions of shallow groundwater consisting of layers and lenses that interbedded with silty layers. Fresh water is found at the depths of 10 - 14 m belonging to Holocene aquifer and the 40 - 60 m deep in upper Pleistocene aquifer, and brackish- salt water is at 24-35 m deep. Analytical results show low level of chloride, sulphate, Fe total, and As total, concentrations, excepting Fe total is high - very high in many places. Two models of Fe treatment from shallow groundwater were established showing good efficiency in Cho Lach and Chau Thanh districts.
