Conclusion E. coli Removal by VFS Oklahoma State University/Woolpert Scholar Conclusion Infiltration is the best way to predict the efficiency of VFS in the removal of E. coli The greater the area of flow, the higher the E. coli Mass Reduction No reduction in E. coli concentrations The inflow rate has only a slight affect on the VFS effectiveness Minimal E. coli were measured in clean water runon experiments two days after diluted manure runon E. coli Removal by VFS Oklahoma State University/Woolpert Scholar Future Work Thicker vegetation Thatch layer Acknowledgements This project could not be completed without the financial support of Woolpert, Inc.
