Cleanup Objectives: Remove trichloroethene (TCE) and destroy explosives in ground water
Greener Remediation Strategy:
Use a 10-kW wind turbine to power ground-water circulation wells (GCWs) for air stripping and ultraviolet treatment
- Calculated a total GCW electricity demand of 767 kWhr each month
- Determined electricity demand could be met by site conditions: wind speed of 6.5 meters/second, shear exponent of 0.27, and turbulence intensity of 0.17-0.21
Results:
- Provides sufficient energy for continued TCE removal and explosives destruction by the aboveground treatment system during grid inter-tie operation
- Reduces consumption of utility electricity by 26% during grid inter-tie operation
- Decreases CO2 emissions by 24-32% during off-grid operation of the system’s 230-volt submersible pump
- Returns surplus electricity to the grid for other consumer use
- Results in no observable impacts on wildlife
- Provides electricity cost savings expected to total more than $40,000 over the next 15 years of treatment
- Estimated that recovery for turbine capital/installation cost could be cut in half by improved GCW freeze-proofing
Property End Use: Continued military operations
Update: February 2008
