DIFFUSION PREVENTION METHOD OF POLLUTED GROUND WATER
PROBLEM TO BE SOLVED: To provide a diffusion prevention method of polluted ground water capable of grasping earlier that diffusion prevention effect of the polluted ground water is likely to be weakening.SOLUTION: There is provided a diffusion prevention method of polluted ground water using a plurality of wells 3 arranged in a soil through which ground water polluted by heavy metals passes and having a water filtration material 9 with dividing inside into an upper part area 31 and a lower part area 32 in a depth direction, ground water in the upper part area 31 is sent to the lower part area 32 in the well 3b of the plurality of the wells, and ground water in the lower part area 32 is sent to the upper part area 31 in the well 3a neighboring the well 3b. The method has a measurement process for measuring concentration of predetermined ion (excluding the heavy metals) in the ground water, a first addition process for adding an immediate active first anaerobic bio agent to the ground water in the well 3 and a second addition process for a long lasting second anaerobic bio agent, timing for conducting the first addition process or the second addition process is determined based on results of the measurement process.SELECTED DRAWING: Figure 1
【課題】汚染地下水の拡散防止効果が低下しつつあることを早期に把握することができる、汚染地下水の拡散防止方法の提供。【解決手段】重金属類で汚染された地下水が通過する土壌に配置され、内部を深さ方向に上部領域３１と下部領域３２とに区分するように遮水材９が設けられた井戸３を複数用いる汚染地下水の拡散防止方法であって、複数の井戸のうちの井戸３ｂでは、上部領域３１内の地下水を下部領域３２内へ送水し、井戸３ｂに隣接する井戸３ａでは、下部領域３２内の地下水を上部領域３１内へ送水する。この方法は、地下水中の所定のイオン（前記重金属類を除く。）の濃度を測定する測定工程と、即効性の第１の嫌気バイオ剤を井戸３内の地下水に添加する第１の添加工程と、持続性の第２の嫌気バイオ剤を添加する第２の添加工程と、を有し、測定工程の結果に基づいて、第１の添加工程又は第２の添加工程を行う時機を判断する。【選択図】図１
