TAILIEUCHUNG - Conditions of the surface water and ground water resources in the rural area of the Mekong Delta, Vietnam
The objective of this paper is the appraisal of the hydrological, hydrogeological, as well as the chemical and microbiological conditions of the surface water and ground water resources of the two study sites. In order to allocate the two study sites into a regional context an intense research on the conditions of the surrounding area was also matter of the survey | Conditions of the surface water and ground water resources in the rural area of the Mekong Delta, Vietnam – exemplary investigations at the study sites An Binh and Hoa An Thomas Nuber1, Harro Stolpe1, Le Anh Tuan2, Vu Van Nam2 1 Environmental Engineering and Ecology, Ruhr-University Bochum, Germany, Univer- sitätsstr. 150, 44780 Bochum, Germany 2College of Technology, University of Can Tho, Can Tho City, Vietnam 1. Introduction As a consequence of a fast-growing economy the Mekong Delta region is facing severe envi- ronmental problems related to industrial and agricultural activities. These environmental problems include soil reclamation (LE QUANG MINH ET AL., 1997), deforestation (MILLER ET AL., 1999) and water quality problems due to pollution of the water resources by pesticides, herbicides and fertilizers (LE QUY AN, 2000). Besides those anthropogenic impacts on the water resources also climatic and geogenic factors play an important role: severe floodings occur during the end of the rainy season (NGUYEN VIET PHO, 2000), surface water bodies are polluted by acid sulphate soils (LE QUANG MINH, 1996), saltwater intrudes into the surface and ground water bodies from the sea (SIWRMP, 1995; NGUYEN HONG TOAN, 2000). Also ground water is often polluted by high chloride or iron concentrations (DO TIEN HUNG ET AL., 2000). In this context a survey was carried out for the rural areas of the Mekong Delta. The goal of the survey was the appraisal of the water resources in terms of quality and availability in or- der to develop a concept for the rural drinking water supply. In the focus of this survey were two exemplary study sites in the rural area of the Mekong Delta. The objective of this paper is the appraisal of the hydrological, hydrogeological, as well as the chemical and microbiological conditions of the surface water and ground water resources of the two study sites. In order to allocate the two study sites into a regional context an in- tense research on the .
