Phytoremediation at RTDF Site I in Illinois
Last Updated: December 2006
Site Information                                                      
Site Name, Location:   RTDF Site I, Southern, IL, United States
Site Type:   Petroleum Refining and Reuse
Is this a Federal
Superfund Site?
  No
Is this a Federal or
Military Site?
  No


Project Information                                                      
Project Name:   Phytoremediation at RTDF Site I in Illinois
Site History and Background:   The site is in a tank farm in a former petroleum refinery. Source of contamination is refined petroleum products (including PRS1 and PRS6) and refinery waste.
Scale:   Pilot/Field Demonstration
Project Status:   Complete
Project Start Date:   November 2000
Project Completion Date:   October 2003
Media Treated:  
Media Qty. Geology Comments
Soil Groundwater is first encountered approximately 10 feet below ground surface (bgs). Depth of contamination is less than 2 feet bgs.
Contaminants Treated:  
Contaminant Initial
Concentration
Depth Media Comments
Total petroleum hydrocarbons 96,000 mg/kg Soil
Polycyclic aromatic hydrocarbons (PAH) 5,784 mg/kg Soil
Phytotechnology Mechanism(s):   Phytostabilization
Rhizodegradation
Plants and other Vegetation Used:   Rye Grass
Legumes
Fescue
Native Prarie Grasses
Planting Description:   Treatment 1: 10 - 15% rye, 20 - 25% legume, 60 - 70% tall fescue Treatment 2: Native prairie grasses and forbs Treatment 3 & 4: Unvegetated
Planting Area:   Not available
Evapotranspiration Rates:   Not available
Climate:   Average temperature range - 18 to 88F; Mean annual precipitation - 46"; Growing season - 196 days; Average first frost - October 27; Average last frost - April 13
O & M Requirements:   Treatments 1, 2, and 3 were fertilized. The unplanted treatments were maintained with the herbicide glyphosate.
Performance Data:   Vegetation grew well at the site, but the established plant species composition was primarily volunteer species rather than planted species.
Cost of the Phytotechnology Project:   Not available
Lessons Learned:   There was no evidence that vegetation enhanced degradation of petroleum hydrocarbons at the site. Additional management would be needed to establish specific plant communities from seed.
