-Ca type, with a weakly alkaline pH. The chemical composition was primarily controlled by weathering and dissolution of carbonate rocks (e.g., calcite and dolomite), cation exchange, and human activities. The APCS-MLR model results revealed that the main controlling factors were water-rock interaction (43.6%), industrial and agricultural (3.9%), agricultural and domestic sewage (10.5%), and unknown source (42%). These findings provide a scientific basis for the sustainable development and effective management of regional groundwater resources.
