This survey was performed to investigate contamination degree and signíficance in each item of 406 samp1es of ground water, which was collected in Seou1 area from J an. to Dec. 1988. The resu1ts of this study were as follows; 1. The unsuitab1e rate of ground water investigated was 69.7%(32.4% in on1y bacteria, 23.6% in both bacteria and physico-chemistry and 13.6% in only physico-chemical contamination). 2. The unsuitab1e rate in each item was the highest(54.2%) in standard p1ate countand 29.8% in coliform, 12.8% in turbidity, 11.3% in Zn, and 10.8% in Mn. 3. The total mean concentrations in each item were 10wer than standard except standard plate count, coliform, and Fe. 4. In the analysis of corelation ,among items, both total hardness and residual solids were showed very high correlatioIl ship (P < 0.01) with other items, and both S.P.C. and coliform showed very high1y significant (P < 0.0 1) with NH3 -N.
