This study aims to determine the characteristics of acidic water derived from void coal mine by taking samples from voids located in South Kalimantan. Method used in this research was field work and laboratory work. The result of measurement of acid characterization of coal mine acid was analyzed to have the highest pH value of 4.01, the highest temperature was 33.9 oC, the highest Color was 3.01 NTU, the highest COD was 56.50 ppm, the highest BOD was 20,34 ppm , The highest DHL of 1 us, the highest TSS of 652.67 ppm, the highest Fe of 9.46 ppm, the highest Mn of 1.72 ppm and the Cd content is still below the defined standard of less than 0.01 ppm. Decree of the State Minister of Environment No. 113 of 2003 on Liquid Waste Quality Standards for Coal Mining.
Key words: Acidic water / Characterization,Coal
