Article Synopsis
- The study examined ion and fluoride levels in groundwater in the southern Hebei Plain from 2018 to 2020, using 336 samples from 112 locations to assess health risks.
- The groundwater types were primarily classified as HCO-Ca, Cl-Na, and SO-Ca, with significant variations in water quality; 60.41% of the samples were suitable for drinking, while 39.59% required treatment.
- Fluoride concentrations varied widely, with 44% of samples below the safe limit (0.5 mg/L) and 8% exceeding the maximum limit (1.5 mg/L), posing risks of dental issues and fluorosis, particularly impacting children more than adults.
