The Influence of Long Xuyen City on the Water Quality of the Hau River (Mekong Delta, Vietnam)

This thesis has been produced as part of the first exploratory study of the water quality of the watercourses in the Mekong Delta, Vietnam, carried out by the “Centre of Environmental Engineering & Renewable Energy, College of Technology, Can Tho University”.
In his research, Pieter Jan Haest has devoted great attention to the measuring of diverse water quality variables: temperature, conductivity, pH, dissolved oxygen, solids, nitrogen, phosphorus, BOD5, COD and the number of coliforms. The aim is on one the hand to estimate water pollution caused by household waste, and on the other to formulate proposals for solving this problem. Haest’s thesis is more than merely a description of measurements. A water quality model is used to study specific situations and draw relevant conclusions.
The developmental relevance of this work is extremely high. It charts the problems of water pollution caused by the city of Long Xuyen in the Mekong Delta, describes the various hydraulic factors that are at the root of the low quality of the water, and puts forwards a number of possible solutions. The feasibility of each of these solutions is examined, not so much on a technical level but rather in social terms, as they indicate a need for changes in mentality on the part of the local population. It would appear from this thesis that with relatively small-scale solutions a great improvement can be achieved, providing the inhabitants of the city can be made sufficiently aware of the problem.
