Dynamics of groundwater geochemistry, contaminant concentration, and microbial phylogenetic and functional structure throughout the 5-year life cycle of an ethanol blend fuel plume

摘要：

Introduction Groundwaterconstitutes the largest terrestrialfreshwater ecosystem,but still belongs to the least exploredone on earth.The capability of groundwater ecosystems to recover from pollutions(such as fuel spills) is a vital concern for environmental scientists.The growing use of ethanol as transportation biofuel is increasing the likelihood of encountering ethanol in current and future fuel releases.However,nostudies have comprehensively investigated the temporalvariability in microbial community structureand the long-term evidence for contaminant elimination and groundwater geochemistry evolution throughout the whole life cycle of a biofuelrelease,from initial plume expansion through its stabilization and eventual disappearance.
