发明名称 METHOD OF ESTIMATING CONCENTRATION OF SPECIFIC ION IN UNDERGROUND WATER, METHOD OF PREPARING HEXA-DIAGRAM, AND METHOD AND DEVICE FOR MONITORING SITE TO BE MONITORED FOR DISPLACEMENT OF GROUND
摘要 PROBLEM TO BE SOLVED: To provide a method of estimating the concentration of a specific ion contained in an underground water at a site to be monitored for displacement of ground which can immediately estimate the concentration of the specific ion without actually measuring the concentration of the specific ion when monitoring the site to be monitored for displacement of ground. SOLUTION: In this method of estimating the concentration of the specific ion in the underground water, the electric conductivity of the underground water in the site to be monitored for displacement of ground and the concentration of the specific ion in the underground water are measured before monitoring the site to be monitored. A regression line A indicating the intensity of the correlation between the electric conductivity of the underground water at the site to be monitored and the concentration of the specific ion in the underground water is obtained according to the measurement data. When the site to be monitored is monitored, the electric conductivity of the underground water at the site to be monitored is measured, and the measurement data is collated with the regression line A to estimate the concentration of the specific ion in the underground water.
