PROBLEM TO BE SOLVED: To provide a purifying method of ground water easily removing pollutant from ground water polluted with boron at a low cost. SOLUTION: A ground water purifying layer 3 is provided in the ground. The ground water purifying layer 3 contains a boron removing component, and boron in the ground water is removed by contact with the removing component. The pollutant removing component is boron selectively adsorbing resin particles having alkali agent particles and an N-methylglucamine group as a functional group. Magnesium oxide or iron powder is used for the alkali agent particles. COPYRIGHT: (C)2008,JPO&INPIT |
