• June 24 - July 1: Experiment Bed Depth:
  Starting with 10 cm on June 24, experiments will be conducted with varying bed depths. Bed depth will be increased 10 cm daily. Final data analysis will occur on June 29-July 1. (Adela, Shaina, Tanya)
• July 1 - July 8: Experiment Bed Expansion:
  The range of expansions to be tested will be determined after the bed depth experiments are conducted. A bed depth that yields moderate gas removal will likely chosen and the physical limitations of the sand column will govern the expansion range. Like in Bed Depth Experiments, expansion will likely be increased incrementally by a certain percentage daily. (Adela, Shaina, Tanya)
• July 8 - July 15: Experiment DO Concentration:
  Starting with 20 kPa gage pressure on July 8, experiments will be conducted with varying aerator pressure and thus influent dissolved air concentrations. Pressure will be increased 20 kPa daily. Data analysis will begin July 12 - July 15. (Adela, Shaina, Tanya)

Note: We plan to completely finish experimentation by July 26. This gives us eleven extra days for these experiments or for addressing additional issues that may arise.
