The analysis of water quality properties in domestic acid mine drainage (coal mine and metal mine) was conducted by using mine drainage database based on the data of existing water quality. The purpose of analysis is to find the relationship between pH and variable cation and anion. Collected data were expressed in terms of mg/L, mole/L and eq/L unit, and carried out a statistical analysis. In comparison of water contamination level of coal mine and metal mine, Fe, Al, Pb, and Cd exceeded two standards ('clean' region and 'Ka/Na' region) of water quality. Mn, As exceeded 'Clean' region and only F⁻ was under the range of two standards. Using pC-pH diagram, pH of drainage was distributed over the strong acid range (pH 2.47-4.52) at both coal mine and metal mine. Also, Fe, Al, Mn, Ca, Mg, SO₄²⁻ were representative ions in the coal mine, and Fe, Al, Mn, SO₄²⁻ were in the metal mine. In the analysis using a charge balance of ions, the effect of Mn ion was relatively less significant than the effect of Fe and Al in the coal mine and the metal mine, but coal mine was influenced substantially by Ca and Mg. The governing degree of each cation arranged Ca>Mg>Al>Fe>H>Mn in the coal mine and Fe>Al>H>Mn in the metal mine. The total ion concentration of the coal mine was much higher than that of the metal mine, and the rate of (total cation)/(total anion) in the coal mine and the metal mine was 94% and 75%, respectively.
