Impact of ZVI and sulfidated ZVI on sulfate-reducing microbial communities and implications for groundwater remediation

Key Points

• This research examines how sulfur-modified zero valent iron influences sulfate-reducing microbial communities and the potential for groundwater remediation.
• Investigated the effects of sulfur-modified ZVI on microbial communities in groundwater settings.
• Analyzed changes in microbial activity and composition post-treatment with ZVI and sulfidated ZVI.
• Compared reactivity and effectiveness of different sulfur species in enhancing ZVI performance.
• Sulfidated ZVI demonstrated increased reactivity compared to standard ZVI.
• Microbial communities showed significant shifts in composition after treatment with sulfur-modified ZVI.
• Enhanced performance of ZVI correlated with higher sulfate-reducing activity in the treated samples.
