Heat Map: Arsenic Risk in China’s Groundwater

Researchers have developed a new statistical model to estimate the risk of arsenic contamination in China’s groundwater, and a heat map has been created based on the research result.


Based on geological, soil, and topological data, a statistical risk model was created by researchers from China and Switzerland to identify high risk areas for groundwater quality monitoring. When these results were combined with the latest available population data, it was found that almost 20 million people across China are living in high-risk areas.
