What this research studies

The team will combine large databases of private well measurements and known contaminated sites with public data on community factors and diabetes rates. They will use advanced geospatial tools (including a Bayesian maximum entropy approach and a Chemical and Social Stressors Integration Technique) to predict arsenic levels in wells that have not been tested. The project will map where arsenic and other contaminants overlap with social stressors and diabetes burden. Results are meant to point to neighborhoods and populations that should be prioritized for well testing, education, or remediation.

Who could benefit from this research

Good fit: People who get their drinking water from unregulated private wells, especially adults in North Carolina or similar areas with known arsenic sources and at risk for type 2 diabetes, are the most relevant population.

Not a fit: People who receive treated municipal water or whose diabetes has no plausible link to arsenic exposure are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could help identify high-risk areas so homeowners and local health officials can target well testing and take steps to reduce arsenic exposure and related diabetes risk.

How similar studies have performed: Epidemiologic studies have linked chronic arsenic exposure to type 2 diabetes, but applying these advanced geospatial prediction methods to untested private wells is a relatively new approach.
