Graph Neural Networks Improve Groundwater Arsenic Prediction

Researchers have developed graph neural networks (GNNs) to predict groundwater arsenic concentrations, addressing a significant public health issue in the United States. By integrating data from over 74,000 arsenic samples across multiple databases, including the Water Quality Portal and Mineral Resources Data System, they created a comprehensive dataset. Their findings indicate that GNNs can match or surpass the performance of traditional methods like gradient-boosted trees by effectively accounting for spatial dependencies in arsenic levels. AI
