METHOD FOR DETERMINING FRESHWATER UTILIZATION OF GROUNDWATER, DETERMINATION DEVICE, AND WATER PUMPING DEVICE FOR FRESHWATER UTILIZATION OF GROUNDWATER
To provide a method for determining the freshwater utilization of groundwater, that can perform determination assuming multiple well depths in one well.SOLUTION: The method for determining the freshwater utilization of groundwater includes: determining the freshwater utilization on an aquifer having salt concentrations of the groundwater different depending on the depth by using a well 10 equipped with a strainer capable of pumping up water from different depths; installing gap filling means 1 at a specific depth of the well 10 to block an underground water flow in a vertical direction of the well 10; pumping up the groundwater from the well 10 above the gap filling means 1 to measure a salt concentration; changing a setting depth of the gap filling means 1 to measure the salt concentration of the groundwater; and thereby determining a utilization depth where freshwater can be used.SELECTED DRAWING: Figure 1
【課題】１つの井戸で複数の深度の井戸を想定した判定を行うことができる地下水の淡水利用判定方法を提供すること。【解決手段】本発明の地下水の淡水利用判定方法は、異なる深度から揚水できるストレーナーを備えた井戸１０を用い、深度によって地下水の塩分濃度が異なる帯水層での淡水の利用を判定し、井戸１０の特定の深度に填隙手段１を設置して井戸１０の上下方向の地下水流を遮断し、填隙手段１より上部の井戸１０から地下水を揚水して塩分濃度を計測し、填隙手段１の設置深度を変更して地下水の塩分濃度を計測することで、淡水を利用できる利用深度を判定することを特徴とする。【選択図】図１
