This paper is the result of hydrogeological survey engineering.

Objective In hydrogeological contexts, biological growth and human health are closely linked to the concentrations of elements present in the surrounding environment, including water and soil. Investigating the formation and evolutionary conditions of both macro and trace elements associated with health in groundwater, as well as establishing regional health geology, is beneficial for advancing the implementation of the Healthy China strategy.

Methods Xiong'an New Area was chosen as the primary research site. The hydrogeochemical characteristics and sources of mineral composition in shallow groundwater were analyzed using multivariate statistical analysis, as well as the Piper and Chadha diagrams. This study restored the water quality by identifying the material element sources of shallow groundwater along a typical profile, delineated hydrochemical types, and classified the differentiation areas of macro and trace elements based on biological necessity, environmental factors, and element abundance or deficiency. Furthermore, it established a health geology regionalization for Xiong'an New Area.

Results The parameters of groundwater exhibited significant variability. The water−rock interactions indicate that the dissolution of albite contributes sodium ions (Na⁺), while the dissolution of fluorite and gypsum contributes fluoride ions (F⁻) and sulfate ions (SO₄²⁻), consuming calcium ions (Ca²⁺), magnesium ions (Mg²⁺), and bicarbonate ions (HCO₃⁻), alongside the precipitation of calcite and dolomite, with reverse ion exchange also occurring. In the northern part of the study area, the predominant hydrochemical types were HCO₃–Ca and HCO₃–Ca·Mg. This composition transitioned to HCO₃·SO₄–Na·Mg·Ca, HCO₃·Cl–Na·Ca·Mg, and HCO₃·SO₄·Cl–Na·Mg in the middle section, ultimately evolving into SO₄·HCO₃–Na·Mg in Baiyangdian and downstream of the Daqing River. Xiong'an New Area can be categorized into three regions: a health geology regionalization characterized by a deficiency of elements in the northern alluvial−proluvial plain; a health geology regionalization with moderate element levels in the interaction zone between the alluvial−proluvial plain and the alluvial−lacustrine plain; and a health geology regionalization with an excess of elements in the alluvial−lacustrine plain. Prolonged consumption of groundwater from both the deficient and excess areas may lead to health issues.

Conclusions It is essential to examine the endemic diseases associated with the local surplus and deficiency of fluoride (F⁻), sulfate (SO₄²⁻), total hardness, and iodide (I⁻) in Xiong'an New Area. Additionally, identifying alternative water sources or supplementing the necessary elements for human health is crucial to support the Healthy China strategy.
