Abstract

It is indicated from the research results that the middle-upper Pleistocene aquifer (qp2-3) in Ca Mau peninsula region has the groundwater source which is formed including static reserves, marginal penetration reserves, and other aquifer penetration reserves, in which the static reserves ranges greatly. The unreasonable exploitation of groundwater with a great number of wells in the qp2-3 aquifer exceeded the limit reserve, as a result, the annual lowering of the groundwater level is very high, and other sustainable values of this aquifer exceeded the limits many times. From the research, it is very necessary to collaborate between the local governments in managing and exploiting the groundwater resource. And the urgent solution is to select the exploitation areas, to balance the reasonable number of wells, and to manage the exploitation volume. Another solution is to research the exploitation capacities of deeper aquifers, and to have an effective plan of using rainwater and surface water resources in parallel.
