Approach

• Installed four groundwater monitoring wells
• Monitored for groundwater depth, oxidation
  reduction potential (ORP), conductivity, and
  temperature
• Analyzed water samples for Iron, Phosphates, and
  Nitrate Nitrogen
• Collected precipitation data

Conclusions

• Groundwater is flowing from the natural wetland
  to the constructed wetland.
• The constructed wetland is a flow through system.
• This is an ongoing research project to determine
  HOW the constructed wetland is affecting the
  natural wetland.

The natural wetland now has surface water (since
February to the present).
