1. Flow Data  Sample data taken from Nov 3 to Nov 19

2. Inflow vs. outflow  Outflow consistently greater than inflow (for both sunny and rainy days with steady cell height)  Instrument error or other unidentified input?

3. Problem of F1 reading Normal F1 Abnormal F1Recirculation Surge

4. Magnetic meters

5. From F2 to F3 to M4  M4 should be less than F2 and F3

6. Discharge From Water Softer Building to LS4

7. Normal F1 Abnormal F1Recirculation Surge F1 consistent with surge tank except during recycle. Backflow problem exists.

8. Expected Errors with open channel flow meters

9.

10. Wetland Performance

11.  Continuing sample analysis  Samples taken from Surge Tank in Oct. & Nov.  Chlorine Test performed in October Wetland Performance AS1-AS4 RemovalLast Year (9/28/05) This Year (9/15/06) TSS82%80% BOD 5 65%67% NH 3 -N68%57%

12.  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

13.  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 Upcoming Work
