Short summary
We investigated the linkage between contaminant mobilization in catchments and their mitigation in vegetated treatment systems (VTSs). We identified different patterns in chemographs recorded at the inlet of a VTS, indicating distinct mobilization patterns that were associated with similar source areas, transport pathways, and discharge dynamics. Peak concentration reduction in the VTS was strongest for sharp-peaked chemographs, suggesting that dispersion was the principle mitigation process.
