3D Plume Replay
55 years of PFAS migration through 10 aquifer layers. MODFLOW 6 heterogeneous transport, Cape Cod validation parameters (K=95 m/d, USGS). Toggle species to watch PFOA race ahead of PFOS.
About this visualization: MODFLOW 6 3D transport with heterogeneous K-fields, calibrated to USGS Cape Cod glacial outwash parameters (K=95 m/d, n=0.39, i=0.0015). Source: 30-year AFFF release zone. Well field 800m downgradient.
The heterogeneous conductivity field produces realistic plume fingering and preferential flow paths. Our Monte Carlo ensemble shifts arrival dramatically earlier at P5 — screening says 96 years, the ensemble says 5.
