Short summary

Organic carbon in aquifer recharge waters and sediments can fuel microbial reactions that affect groundwater quality. We used high-resolution mass spectrometry to molecularly characterize organic carbon mobilized off sediment collected from a Bangladeshi aquifer, to reference its composition against dissolved organic carbon in aquifer recharge water, to track compositional changes during incubation, and to advance understanding of microbial processing of organic carbon in anaerobic environments.
