AB  - Bank filtration is a powerful and established barrier for pathogens and organic 
      pollutants. The aerobic degradation of the pollutants competes with the microbial 
      respiration of dissolved and particulate organic matter (DOC and POC). The fate 
      of terrestrial POC (tPOC) in bank filtration is currently not fully understood. 
      In the present study, fallen leaves of different local trees were milled, 
      characterized and investigated as tPOC in both batch and column experiments. The 
      respective contents of carbon and nitrogen differed slightly, but the different 
      leaves released significantly different DOC fractions as determined by 
      size-exclusion chromatography. While high molecular weight biopolymers were 
      degraded by indigenous microorganisms, humic substances were not degraded within 
      96days in batch experiments. DOC release and POC wash-out in column experiments 
      led to a slight decrease of tPOC depositions, but more than 80% of the initial 
      tPOC remained after 54days thus representing a long-term organics reservoir for 
      microbial respiration. The release of humic substances from autumnal leaf litter 
      inputs is a plausible explanation for comparably high DOC concentrations 
      (approximately 4.5mg/L) in Berlin drinking water that mainly originates from lake 
      bank filtration.
