- Sedimentary environment is the key factor to control the As, F, I distribution.
- Four sedimentary zones were divided on the basis of Clay-sand ratio, clay layers and terrain slope.
- High As and I is distributed in paleochannel zone with strong reducing environment.
- High F comes from the fluorine-rich bedrock surrounding the basin.

- The enrichment of arsenic in groundwater is closely related to salt content of aquifer medium.
- Reduction environment caused by high organic matter content is key to arsenic enrichment.
- Alkaline environment has great influences on the enrichment of fluoride and arsenic compounds.
- Dissolution balance between carbonate minerals and fluorite controls the content of fluoride.

• High fluoride groundwater risk map was generated.
• Climate variables are the most important indicators.
• High fluoride risk areas comprise a total of 27.6% of the country.
• About 89 million rural people are at health risk due to fluoride exposure.
• The risk map can be used by authorities to prioritize fluoride mitigation.
