Ground water samples of 275 were collected from Gapyeong county which it contained six-eup and myeon and analyzed for 12 mineral inorganics extending from March to October in 2004.<br/> Among the inorganics, Calcium, Magnesium, Sodium, Potassium, Copper and Zinc had more than 70% of detection frequencies, which coincided with essential inorganics required by the human body. The average values of inorganic contents by sampling sites were insignificant. Fluorine contents of 8 samples, 2.9% of 275 samples, exceeded KDWR, and it was considered to be affected by a base rock being made up granite and gneiss because there were not polluting sources around. It is necessary to find out relation between geological characteristics and mineral inorganics in ground water through the further investigation.<br/> Compared to noted concentrations of bottled water, inorganic minerals including Calcium, magnesium, Sodium and Potassium related to taste were fluent double in target samples and those average concentrations were 14.80, 3.80, 7.60, and 2.31 ㎎/L respectively.

Objectives: The purpose of this study was the investigation of bromide and bromate in drinking water of water supply plants, mineral springs and small water supply system located in northern area of Gyeonggi province. Methods: Analytical method was based on EPA 326.0 to use Postcolumn reaction (PCR). The instrument was 887 professional UV/VIS detector IC manufactured in Metrohm. Results: Bromate was detected at 0.5~2.4 µg/L in tap water from 5 water supply plants. These plants were used as disinfection method for sodium hypochlorite and on-site chlorine that causes generate bromate as a by products even if not used ozone. Conclusions: The bromate was detected up to 2.5 µg/Lin drinking water in northern Gyeonggi area that showed within 10 µg/L for standard of tap water. However, the continuous monitoring of bromate is necessary in drinking water.
