In this paper, two leaching tests(batch test & column test) were carried out to estimate the detrimental effects of coal ash leachates. The variation of constituents and concentration of coal ash leachate with the lapse of leachins time was analysed through the column tests. From the test results, it was found coal tach can be classified as a general waste, and all other items except pH of coal ash leachate are satisfied the concentration requirements for the drinking water. It was also found the concentration of coal ash rapidly decrease with the lapse of the leaching time and become the insignificant value after an elapsed time.
