Impact of human activities on groundwater biogeochemical cycles and microbial communities: Insights from metagenomic analysis

Key Points

• Alterations in microbial communities indicate significant effects of human activities on groundwater.
• Metagenomic analysis identified key shifts in nutrient cycling and biogeochemical processes.
• Analysis of groundwater samples across multiple regions demonstrated pervasive impacts from agricultural runoff and urbanization.
• These findings underscore the need for improved management practices to protect groundwater resources.
