Project Information |
|||||||||||||||||
| 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 |
