Abstract | Bangkok has a serious problem of groundwater contamination by saltwater encroachment. If the present rate of contamination continues, the city is going to face an acute shortage of potable groundwater which is a major source of its water supply. The cause is mainly due to heavy withdrawal of groundwater for public water supply and also by private enterprizes such as industries, hotels( educational institutes, housing estates etc. Out of the eight aquifers which underlie Bangkok area, the present study concentrates on Phrapradaeng aquifer, It appears that a saline water body which occupies the western side of the Chao Phraya River is the source of contamination. The present study formulates the t wo-dimensional numerical model and then analyses the problem with the available one-dimensional and two-dimensional models separately. This study concludes that, apart from the movement of salt water from the Gulf of Thailand, the connate water body acts as a predominant source of contamination of freshwater in Bangkok. This al so delineates approximately the saline water body. Furthermore, possibilities of vertical leakage of saline water from upper aquifers are also shown. |
