Contamination with potentially toxic elements (PTEs) frequently occurs in surface water coal mining areas. This study analyzed 34 samples collected from the Yunnan–Guizhou Plateau for their hydrochemical characteristics, spatial distribution, source apportionment, and human health risks. Our statistical analysis showed that average concentrations of PTEs ranked as follows: Fe > Al Zn Mn Ba B> Ni Li Cd Mo Cu Co Hg Se As Pb Sb. The revealed high Fe, Al, were predominantly distributed main stream, Xichong River, Yangchang River. Positive matrix factorization (PMF) identified four sources water. Hg, As, originated wastewater discharged by preparation plants mines. Mo, Li, B dissolution clay minerals seams. Elevated Cu, Mn, Co, attributed to kaolinite, illite, chalcopyrite, pyrite, associated Cd, Zn, derived melting traffic release. deterministic risks assessment 94.12% presented non-carcinogenic below limit 1. Meanwhile, 73.56% elevated posed level III carcinogenic risk local populations. Special attention drinking safety children is warranted due lower metabolic capacity detoxifying PTEs. provides insight PTE management sustainable environments.
