In this paper, the soil pollution condition of a typical chromium-containing slag heap in the North China plain were analyzed on the basis of previous data and the test during the field investigation. The hexavalent chromium content contour map was drawn. The regional soil chrome pollution level was evaluated by using single factor index method and potential ecological harm index method. The results of the single factor index method show that soil surrounding chromium-containing slag heap was seriously polluted. However, the results of the potential ecological harm index method evaluation show a slight pollution, which indicates that the area of chromium slag is not significantly harmful to ecology of the surrounding soil.
