Flow Data. Sample data taken from Nov 3 to Nov 19. Inflow vs. outflow. Outflow consistently greater than inflow (for both sunny and rainy days with steady cell height) Instrument error or other unidentified input?. Recirculation. Abnormal F1. Surge. Normal F1. Problem of F1 reading. - PowerPoint PPT Presentation

Samples taken from Surge Tank in Oct. & Nov. Chlorine Test performed in October
Wetland Performance
AS1-AS4 Removal Last Year(9/28/05)
This Year(9/15/06)
TSS 82% 80%
BOD5 65% 67%
NH3-N 68% 57%
Chlorine Test Sample analyzed from AS-2 DPD Titrimetric test: positive results
Oxidizing agents (Chlorine or other products) may be present in waste stream Found in antibacterial soaps, cleaning supplies Possible cause for stress to plants
Wetland Performance
DPD Colorimetric test Can determine quantity of oxidizing agent
present To be done at more sampling points
Are septic tanks working properly? Biodegradation occuring, or Settling system, oxidants bypass DPD test will give insight
