      다국어 초록 (Multilingual Abstract)

      This study was carried out to investigate of physico-chemical status of drinking ground water near by the Gum-ho river basin, from February, 20 to March, 20, 1986.
      The ground water for testing was sampled 26 sites which are eleven wells, twelve electric pumps, and three simple piped water.
      Out of 23 kinds of phsico-chemical factors investigated, hydrogen ion, alkalinity, nitrate nitrogen, sulfate, copper, zinc, hexavalent chromium, arsenic, mercury, and lead were within allowable values for drinking. However, total hardness (sites Ⅴ-1 and Ⅵ-1), turbidity(site Ⅴ-2), ammonia nitrogen(site Ⅲ-2), chlorine(sites Ⅲ-2, Ⅲ-4, Ⅳ-1, Ⅴ-1 and Ⅵ-6) iron (site Ⅳ-2), manganese(sites Ⅱ-1 and Ⅲ-2) cadmium(sites Ⅰ-1 and Ⅲ-2), were higher than allowable value.
      The shorter straight distance from Gum-ho river side to sampling points, the higher concentration of alkalinity, carbon dioxide and sulfate(p<0.05).
      The concentration of sulfate, arsenic, and lead were negatively correlated with depth of ground water (p<0.05).
      In comparision of water supplying style and chemical contents; ammonia nitrogen, sulfate, lead, arsenic and mercury were higher in the well water than in the simple piped water(p<0.05).
      The pollution of ground water was high negative correlation with the distance of contamination sources such as toilet, cattle shed, rice field, etc.
