NOTES:
1)EAD amendment dosing additives and amounts may vary based on recent groundwater data,injection back-pressures,and product availability.
2)Water flush volumes may vary based on recent source area and down-gradient groundwater data.
3)Injected volumes shown in italics are estimated due to operational issues with segment flow meters.
4)Segments 410&420 may receive lower amounts of amendments due to apparently lower injection yields as indicated by daylighting of injected fluids at wells including B03,1304,C04,D05,D08.
