Destination and period: Mekong Delta and Hue city, Vietnam, from 3rd Sep to 10th Oct, 2012
The overseas field training in Vietnam from 03/09/2012 to 16/09/2012 has provided me mamy knowledge about environmental issues in the Mekong Delta and Hue city in Vietnam. During the training has studied the character of surface water in the Mekong River wastewater, I found that the water quality in mainstream of the Mekong River in Vietnam (Hau and Tien River) indicated by some chemical parameters such as COD, EC, and ions concentration was within the standard for surface water in Vietnam, while those characters of water in sub-stream of the river were at higher concentration, especially sub-streams in the city area and in drainages from aquaculture farming area. Besides, a visit to Water Supply Company in Can Tho city has provided us understanding of the surface water environment was in high pressure of pollution by impact of urbanization and understanding of technology of treating domestic water from surface river water. Additionally, we also learned about the integrated farming system which including generating biogas for family consuming from husbandry waste, and visit O Mon landfill to learn about the impact of solid waste management. Finally, visiting Bach Ma National Park was great chance to learn about how the charcoal project staff have set up activities for improving livelihood of local people in buffer zone by charcoal-applied environmental friendly farming models.
Key words: Water quality, environmental issues, Mekong River Delta, Bach Ma national Park, Vietnam
