The analytical results of contaminant materials in all the samples were suitable for drinking water stalldard. The mean value of NII,,-N , N03-N , Cl-and KMII01 consumption were ND. 49mg/1‘ 1.08mg / 1 anà 8.14mg / i, respectively. 2. Total bacterial counts were 3/ cc in average and Coliforms was negative in all samples 3. The analytical results of Heavy metals were not detected or detected in a small amount‘ and the contents were different from each company. The CN, Hg, P were not detected in all the samples and the mean value of Cu. Fe. Mn were O.0087mg / 1, O.0303mg / 1. O.018mg / t, respectively 11-nd it’s contents were low‘ 4. The mean value of Pb, Zn, Cr+b , As and Cd were O.016mg / t, O.015mg / /, O.0025mg / I ‘O.OOfi9mg / 1 and O.OO l1 mg / 1 respectively.
