ABSTRACT
Groundwater monitoring and social-economic development data were collected to explore the
effect of rapid urbanization on groundwater environment and quality. The results show that the
groundwater table continuously declined from 13.96 m to 43.25 m between 1972 and 2015. Groundwater
hydrochemistry in the Shijiazhuang area changed from a HCO3-Ca (Mg) to HCO3. SO4-Ca (Mg) type,
becoming more diverse and complex. Groundwater environments have changed, caused by the oxidationreduction
environment changing, the vadose zone thickening, and the proportion of impervious surface
area sincreasing. Groundwater quality has deteriorated significantly and NO3- and hardnes shave
exceeded grade III of the Chinese national groundwater quality standard range. The concentrations of
Cl-, Mg2+, NO3-, salinity and hardness significantly correlate with gross domestic product, permanent
population, and population density. The driving factors causing groundwater quality deterioration are
population growth, social and economic development, and over-exploitation of groundwater. Therefore,
the state and the administration are trying to protect the groundwater environment while pursuing a
rapid socioeconomic development.
