This study evaluated the microbial community structure and functional capability associated with the Middle Branch passive remediation system in Central PA. Sediment and water samples were collected from areas within the passive remediation system and its receiving stream. Environmental parameters associated with the system explained a significant amount of variation in microbial community structure. The study revealed shifts in microbial community structure from acidophilic bacteria in raw AMD discharge to a more metabolically diverse set of taxa toward the end of the system. Vertical flow ponds and the aerobic wetland showed strong metabolic capability for sulfur redox environments. This study supports previous investigations that demonstrated the effectiveness of sulfur-reducing bacteria in the process of removing sulfate and heavy metals from contaminated water. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6716070/pdf/fmicb-10-01955.pdf
