Ratio of the local population could be accessed the safe drinking water in Trang Bang district which recording of low frequency. The study was conducted the sampling and evaluation of water quality in nine rural water supply stations in Phuoc Chi, Binh Thanh and Phuoc Luu communes, Trang Bang district. Analyzing results of the important water quality parameters at the rural water supply stations in Trang Bang district showed that these parameters met requirements National Technical Regulation on domestic water quality QCVN 022009/BYT and drinking water quality QCVN 012009/BYT. However, some monitoring samples ofE.coli level did not meet the water supply requirements for domestic and drinking purposes. Correlation coefficients among water quality parameters illustrated the strongly relationships at statistically significant (p<
0.05). Results of PCA showed three principal components (PCs) with obtainable eigen values was equal to 1.287 and total cumulative variance within 86.426%. It means the studying results could be used to assessing and interpreting of domestic supply water quality status in Trang bang district, Tay Ninh province.
