Ground water samples were collected from residential, green" industrial, landfill and mining area and analyzed for 23 inorganics from March to October in 2002.<br/> The results are as follows;<br/> 1. The detection frequencies of inorganic materials such as As, Ba, B, Mo, Ca, Mg, AI, Cu,<br/> Fe, Mn, Zn, Na, K were 7.2-77.1% which showed that these inorganics were detected in many ground waters.<br/> 2. The detection frequencies of 7 inorganics (Cd, Cr, Pb, Se, Sb, Be, TJ) were commonly low<br/> at ranging from 0.42 to 2.5%. These inorganics were contained in ground water partially.<br/> 3. Three inorganics such as Hg, Ni, Ag were not detected in any ground-water samples. 4. Compared to the other areas, ground water samples from landfill area contained greater<br/> concentration in many inorgainics and then showed higher levels in industral, residential,<br/> mining and green area in order.<br/> 5. Compared to noted concentrations of bottled water, inorganic minerals including Ca, Mg,<br/> Na, K related to taste were fluent in target samples. The results showed that the average<br/> concentrations of Mg, Na, K were 4.0 mg/ℓ, 14.7 mg/ℓ, 1.5 mg/ℓ respectively.<br/> 6. The concentrations of inorganics such as Sb, Ba, Mo, Be, Tl, K in some ground water<br/> samples exceeded the water quality standards of WHO, the US and UK<br/> Especially, Ba, Mo, K also showed relatively high detection frequencies so these inorganics need to be considered as analytes in Korea Drinking Water Regulation in further study.
