Geochemical Predictors of Arsenic Contamination
Approximately 3 million North Carolinians depend on wells as a source of drinking water, yet it has been estimated that more than 75,000 consume well water with arsenic levels that are thought to be unsafe.
Researchers from Project 4 seek to understand the fundamental chemical relationships between dissolved metals such as inorganic arsenic, chromium and vanadium, and aquifer rocks and sediment. With these results, they will develop models to predict the vulnerability of groundwater to toxic metal contamination and inform future well placement.
By understanding the factors that lead to or prevent groundwater contamination, better management strategies can be developed to reduce human exposure to toxic metals. Findings from this research will provide key information to help guide new well placement and identify conditions that cause existing wells to be at risk for contamination.
