Abstract:

Prediction of groundwater quality evolution has always been a difficult issue, with its implications largely limited by the sole dependence of historical data for the evaluation. Taking Shijiazhuang area as the stu-dy area, we put forward a method to revise the water quality evolution trend shown by historical data, and predict the water quality change by using the degree of current human activity influence on groundwater as a correction factor. The four major indices of shallow groundwater at Shijiazhuang (i.e., total hardness, TDS, $NO_3^-$ and Fe) were used as prediction indices for the evolution of representative indices in 2025. The results show that the water quality deterioration areas for TDS and total hardness are mainly in the southeastern part of the Lingshou County, Gaocheng District and Wuji County near the Hutuo River. The deterioration areas for Fe are mainly distributed in the central and southeastern parts of Shijiazhuang City, and those for $NO_3^-$ are near the junction of Luquan District and Lingshou County, northwestern Shijiazhuang City and around the Hutuo River in Gaocheng District. The predicted results are in good agreement with the hydrogeological conditions, the man-made pollution sources and groundwater extraction in the study area.
