Monitoring Methods
2
Phytoremediation System Monitoring Tools

• Collect monitoring well data
• Water levels
• Analytical

3
Phytoremediation System Monitoring Tools

• Collect tree core samples
• Collect transpired stem gas

4
Phytoremediation System Monitoring Tools

• Collect weather data
• Collect soil moisture

5
Phytoremediation System Monitoring Dynagage
Sap-flow Sensors

• Measures change in temperature as sap flows past
  heated collar

6
Phytoremediation System Monitoring Thermal
Dissipation Probe (TDP)

• Measures temperature dissipation between a heated
  probe and a reference probe

7
Objectives of the Sap Flow Monitoring

• Develop hydrologic budget
• Determine sap flow relative to tree diameter
• Determine sap flow relative to weather (ET)
• Determine groundwater usage for plantation
• Refine MODFLOW model input to more accurately
  predict remedial progress
• Determine monitoring plan for next season

8
Sap Flow Data Collection

• Using Dynamax Flow32, FLGS Systems
