内容記述 |
The survey of the water quality of wells was carried out in Hoa Thuan village in Me Kong Delta of Viet Nam, August 1996. The village is situated beside the mouth of the Me Kong River. The wells are on the sand ridge which extends from north to south. The results are summarized as follows : 1) The electric conductivity, the concentrations of NH_3-N, Fe and Cl^-, the hardness and so on of the water of the deep wells are higher those of shallow wells. Those values of the deep wells on the sand ridge decrease as the well stands apart from the other toward the south. This is considered to occure from increase of the distance between the sand ridge and Co Chien River. 2) The value of NH3-N in the deep well is higher than that of shallow well, and this is caused by the organic matter which is accumulated in the deep layer. 3) Excepting the well in the northern part which have water like sea water with respect to the salinity, the shallow wells have water exhibiting the low level salinity. 4) The deep wells are classified into three groups according to the water quality, that is, the well highly contaminated (located on the north end of the ridge to about 4 km point toward the south), medially contaminated (located to about 7km point) and low contaminated (located to about 10km point). |
