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, B04, CO4, DOS, D08. 2000 12,000 1/4/2023
