Per- and polyfluoroalkyl substances (PFAS), known colloquially as "forever chemicals," have been associated with adverse human health effects and have contaminated drinking water supplies across the United States owing to their long-term and widespread use. People in the United States may unknowingly be drinking water that contains PFAS because of a lack of systematic analysis, particularly in domestic water supplies. We present an extreme gradient-boosting model for predicting the occurrence of PFAS in groundwater at the depths of drinking water supply for the conterminous United States.

- The study examines how redox conditions in groundwater influence the movement of nutrients and contaminants, which can impact human health, highlighting the importance of understanding these conditions across large areas like the contiguous United States.* -
- Using a machine learning technique called random forest classification, researchers predicted groundwater redox conditions by analyzing data from over 30,000 wells and identified significant factors like geology, soil properties, and hydrologic position that affect oxic (oxygen-rich) conditions.* -
- The findings indicate that the likelihood of having oxic groundwater is closely related to factors like stream proximity, depth from the water table, base flow index, and topographic wetness index, suggesting how water movement and soil characteristics play a role in oxygen levels in
