The present study was conducted to evaluate the breakthrough curve for nickel adsorption in fine‐grained soil from a nearby ash pond site of a thermal power plant. Nickel was found to be the major polluting solute in the ash sluicing wastewater. The adsorption of nickel by vertical soil column batch test and horizontal migration test was carried out in the laboratory. Field investigation was conducted also, by installing test wells around the ash pond site. Experimental results showed a good adsorptive capacity of soil for nickel ions. The breakthrough curves showed a reasonable fitting with a one‐dimensional mathematical model. The breakthrough curves yielded from field test results showed good agreement with a two‐dimensional mathematical model.
