The current study investigated long-term fate (persistency and bio-transformation) of several emerging contaminants in a simulated bank filtration (BF) for the first time. In parallel, four sand column systems were operated with groundwater and continuously spiked with an average concentration of 1 μg/L for 24 OMP. Each column system consisted of two sand columns connected in series. Presumably, biological activities in the first column were higher than in the second column, as dissolved oxygen utilization, dissolved organic matter (DOM) and UV absorbance at 254 nm (UV₂₅₄) reduction ratHeliyone15822https://www.ebi.ac.uk/biostudies/studies/S-EPMC10163653biostudies-literatureTransformation of potentially persistent and mobile organic micropollutants in column experiments.PMC10163653Schumann PZeeshan MPabst SRuhl ASfalseTransformation of potentially persistent and mobile organic micropollutants in column experiments.The occurrence of potentially persistent and mobile (PM) organic micropollutants (OMP) in the aquatic environment is recognized as a severe threat to water resources and drinking water suppliers.
