| Project Name: | Phytoremediation at RTDF Site J in Arkansas | ||||||||||||||||
| Site History and Background: | The site is an oil storage/separation facility. Source of contamination was a crude oil spill that occurred in 1997. | ||||||||||||||||
| Scale: | Pilot/Field Demonstration | ||||||||||||||||
| Project Status: | Complete | ||||||||||||||||
| Project Start Date: | October 1999 | ||||||||||||||||
| Project Completion Date: | October 2001 | ||||||||||||||||
| Media Treated: |
| ||||||||||||||||
| Contaminants Treated: |
| ||||||||||||||||
| Phytotechnology Mechanism(s): | Phytostabilization Rhizodegradation |
||||||||||||||||
| Plants and other Vegetation Used: | Rye Grass Legumes Fescue Bermuda Grass |
||||||||||||||||
| Planting Description: | Treatment 1: Tall fescue, ryegrass Treatment 2: Bermuda grass, tall fescue Treatment 3: Unvegetated Vegetated plots were fertilized with inorganic fertilizer and dolmitic lime at 1,600 kg/ha and 1,450 kg/ha respectively at planting. | ||||||||||||||||
| Planting Area: | 4,800 square feet | ||||||||||||||||
| Evapotranspiration Rates: | Not available | ||||||||||||||||
| Climate: | Average temperature range - 30 to 92F; Mean annual precipitation - 53"; Growing season - 180 days; Average first frost - October 22; Average last frost - April 16 | ||||||||||||||||
| O & M Requirements: | Vegetated plots were fertilized with 320 kg/ha of inorganic fertilizer 6, 17, and 21 months after planting. Unvegetated plots were weeded with glyphosate. | ||||||||||||||||
| Performance Data: | Concentrations of TPH and PAHs declined, and one sampling method showed that concentrations in the vegetated treatments were found to be significantly lower than the unvegetated treatment. Greater decreases in PAH concentrations were observed for PAHs with fewer rings and less alkylation. Tall fescue, Bermuda grass, and ryegrass produced good cover at the site. | ||||||||||||||||
| Cost of the Phytotechnology Project: | Not available | ||||||||||||||||
| Lessons Learned: | The large decline in hydrocarbons concentration showed the petroleum source had residual degradability, and phytoremediation with fertilization appeared to be an effective treatment method. | Point(s) of Contact |
