Comprehensive analysis of groundwater hydrochemistry and nitrate health risks in the Baiquan basin, Northern China.

ABSTRACT: Groundwater is a crucial water source and strategic resource, essential for sustaining both urban and rural livelihoods, supporting economic and social development, and maintaining ecological balance. This study investigates the hydrochemical properties and controlling factors of groundwater in the Baiquan basin (BQB) by analyzing water quality data collected during both dry and wet periods. Additionally, the suitability of groundwater for drinking and agricultural irrigation was evaluated. The findings reveal that groundwater in BQB is generally weakly alkaline and primarily consists of hard-fresh water. Although there are seasonal variations in the main ion concentrations, HCO₃ ^- and Ca²⁺ are the predominant anions and cations, respectively. Consequently,
