Groundwater Quality Assessment and Its Suitability for Domestic and Agriculture Uses in Coastal Zone of Mekong Delta, Vietnam
1st Aug., 2013 – 19th Aug., 2013
The field training activities were conducted at College of The Environment and Natural Resources, CanTho University, CanTho city and Vinh Chau district, Soc Trang province. The study area is Vinh Chau, part of the SocTrang province, which is located; downstream part of Mekong Delta, coastal zone and borders to East Sea of Vietnam. In the area, the groundwater resources are developed for water supply and irrigation purposes. Through the discussions, samplings and laboratory works, hydro-chemical evaluation of groundwater was conducted. In order to evaluate the quality of groundwater in study area, 31 groundwater samples included 21 samples at domestic wells and 10 samples at irrigation wells, were measured on site and analyzed in laboratory for various parameters. As a result, groundwater chemistry was assessed for domestic and agriculture uses and by consideration of water quality index factors from World Health Organization and United States Salinity Laboratory. In addition, the investigation and sampling experiences were shared by lecturers and staffs from Cantho University and local government at study site and discussions. Due to coastal zones in Mekong Delta is facing climate change and natural disaster, which are increasingly serious, studies relevant to environment and water have been concerned by local government. The results of the field study will be contributed to annual environment report of VinhChau district and considered as the first step to develop studies of groundwater which is an important resource in the future.
