Abstract

This survey was performed to investigate contamination degree and significance in each item of 406 samples of ground water, which was collected in Seoul area from Jan. to Dec. 1988. The results of this study were as follows 1. The unsuitable rate of ground water investigated was 69.7%(32.4% in only bacteria, 23.6% in both bacteria and physico-chemistry and 13.6% in only physico-chemical contamination). 2. The unsuitable rate in each item was the highest(54.2%) in standard plate countland 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 lower 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 correlationship (P < 0.01) with other items, and both S.P.C. and coliform showed very highly significant (P < 0.01) with NH$_3$-N.
