Christopher Whitfeld and Wenqi (Jonathan) Zhao from the United Kingdom receive the prestigious Stockholm Junior Water Prize 2024 for their work on PFAS pollution in the Thames Basin. HRH Crown Princess Victoria of Sweden presented the winners with their award during a ceremony at World Water Week in Stockholm.

Per- and polyfluoroalkyl substances (PFAS) pollution is a growing concern worldwide. Focusing on the Thames Basin in the United Kingdom, where there are with no equitable solutions to the problem, Whitfeld and Zhao developed a geospatial neural network, predicting PFAS values to within 10 percent of experimentally validated values. For this, they were announced the winners of the Stockholm Junior Water Prize, an international competition where students between the ages of 15 and 20 present solutions to major water challenges.

The winners were presented with their prize during an award ceremony at World Water Week by HRH Crown Princess Victoria of Sweden, the Prize’s Official Patron.
