Project Name: | Phytoremediation at RTDF Site B in Ohio | ||||||||||||||||
Site History and Background: | This site was a land farm at a former petroleum refinery where tank bottoms from the refinery were placed for bioremediation. Source of contaminants are slop oil and API separator sludge. | ||||||||||||||||
Scale: | Pilot/Field Demonstration | ||||||||||||||||
Project Status: | Complete | ||||||||||||||||
Project Start Date: | April 1999 | ||||||||||||||||
Project Completion Date: | December 2002 | ||||||||||||||||
Media Treated: |
| ||||||||||||||||
Contaminants Treated: |
| ||||||||||||||||
Phytotechnology Mechanism(s): | Phytostabilization Rhizodegradation |
||||||||||||||||
Plants and other Vegetation Used: | Hybrid Poplar Hackberry Rye Grass Legumes Fescue Willow |
||||||||||||||||
Planting Description: | Treatment 1: Perennial ryegrass and tall fescue plus goldenrod and orchardgrass in the later years Treatment 2: hackberry and cool-season grasses Treatment 3: willow, poplar, and cool-season grasses Treatment 4: unvegetated The first year after planting was a drought year, and there was low success of tree establishment. Willow and poplar trees were replanted in 2000. | ||||||||||||||||
Planting Area: | 19,600 feet | ||||||||||||||||
Evapotranspiration Rates: | Not available | ||||||||||||||||
Climate: | Average temperature range - 20 to 86F; Mean annual precipitation - 41"; Growing season - 175 days; Average first frost - October 15; Average last frost - April 15 | ||||||||||||||||
O & M Requirements: | Vegetated plots were fertilized. Unvegetated plot was weeded by hand. | ||||||||||||||||
Performance Data: | After the first drought year, vegetation growth was good with plant cover between 60 - 95%. However, there was no evidence that vegetation enhanced degradation of petroleum hydrocarbons at this site. | ||||||||||||||||
Cost of the Phytotechnology Project: | Not available | ||||||||||||||||
Lessons Learned: | Field tests of phytoremediation using weathered refinery source material are unlikely to result in clear treatment effects unless other measures are taken to manage the variability. | ||||||||||||||||
Comments: | Hackberry trees never established, so treatments 1 and 2 were essentially the same. | Point(s) of Contact |
