Ground Water Age Predictor (GWAP): Groundwater ages provide insight into recharge rates, flow velocities, and vulnerability to contaminants. The ability to predict groundwater ages based on more accessible parameters via machine learning (ML) would advance our ability to guide sustainable management of groundwater resources. In this work, ML models were trained and tested on a large dataset of tritium concentrations (n=2410) and tritium-helium groundwater ages (n=1157) from the California Central Valley, a large groundwater basin with complex land use, irrigation, and water management practices. The dataset collected by the California Waterboards for the Groundwater Ambient Monitoring and Assessment (GAMA) program and can be downloaded.
