- Previous work examining groundwater and sediment attached communities indicated that sediment communities were more taxonomically and functionally stable than groundwater and were, in total, responsible for more activity.
- In a contamination plume, water flow, oxygen and differential contaminant flow and mineral content are expected to constrain the functional identity and activity of these communities.
- This deep of contrasting sediment provides a nearly unprecedented view into the sediment environment that bounds microbial dispersal, growth and activity
- This study sets the stage for a detailed analyses of the distribution of these biological factors under spatially-distributed, differential flow conditions
