Abstract
<p> Groundwater pollution with nitrate is a serious environmental challenge. The nitrate levels in the study area have been exceeding the acceptance levels in Japan. In the most cases, a batch test is applied to determine the pollutant content in the soil. In this study, the elution amount of nitrate was evaluated with the breakthrough curve obtained from the column experiment, and the validity of the batch test was examined. As a result, it was found that the solid-liquid ratio of 1:3 could be sufficiently eluted for nitrate in the column experiment. The results of the three elution tests; the column test, the batch test, and the stirring test, showed that almost same amount of nitrate eluted.</p>
