The research was conducted on groundwater exploitation and usage in Ward 2, Vinh Chau Town, Soc Trang Province. A total of 405 households were interviewed about enduse water status. Groundwater samples from 9 wells were monitored once for water quality status. The results of the study indicated that there was a total of 520 wells installed at 405 households showing that water is urgently needed for domestic use (88.7%), and agricultural use (69.5%). There were 41.4% of the wells drilled since 2010 up to now and 74.3% of the wells drilled over 100 m. To get more water, particularly in dry seasons, the farmers applied large intake pipes (96.4% of the well’s pipe diameters were 49 and 60 mm) and illegally pumped (syringes pump, air pump, or rocket pump) which led to a decrease in groundwater levels and caused pressure on water source. Groundwater quality is within threshold values of national technical standards. Appropriate pumping technique was a suggestion to the farmers. Local authorities need to pay more attention to groundwater management in this area that help farmers use this resource.
