Studies on the Mineral Water in Seoul Area

서울시 일원 약수의 수질에 관한 조사연구

This study was carried out to investigate water quality and pollution in the mineral water located in Seoul area. 15 sites were pointed out by random sampling and tested monthly for 14 items from July to December in 1986. 1. 14 sites were suitable for the drinking water standards but 1 site was not suitable for its pH (5.4). 2. The range of mineral element and concentration were as follows: $$K\;(1.1\pm0.19\~2.38\pm0.45ppm)$$ $$Na\;(5.14\pm0.32\~11.2\pm0.58ppm)$$ $$Ca\;(4.36\pm0.53\~14.44\pm0.53ppm)$$ $$Mg(1.58\pm0.32\~6.34\pm0.77ppm)$$ 3. Among the heavy metals, Fe, Zn, Mn, Cu, were detected small amount but Pb was not detected in all sample. 4. Fluoride concentrations were the range of $0.13\pm0.03\~0.42\pm0.03ppm$.
