This research uses a data-driven approach, specifically random forest classification, to predict groundwater contamination risk from PFOS and PFOA in Colorado. The model incorporated known and potential PFAS sources, environmental characteristics, and existing sampling data. Results showed good sensitivity and precision in predicting high and low-risk areas, identifying private wells, schools, mobile home parks, and public water systems as priority sampling locations. The study also highlighted data gaps and recommended focusing limited resources on vulnerable populations.
