| Project Name: | Phytoremediation at Oregon Poplar Site in Oregon | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Site History and Background: | Contamination at the site is probably the result of illegal dumping activities. Site had been an abandoned, grassy field for many years prior to commencement of the phytoremediation project. It is estimated that 8,100 cubic yards of contaminated soils was excavated from the site in 1995 as part of an interim remedial action measure. There has been no pressure to develop this parcel for immediate land use. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Scale: | Pilot/Field Demonstration | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Project Status: | Ongoing | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Project Start Date: | 1997 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Media Treated: |
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Contaminants Treated: |
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Phytotechnology Mechanism(s): | Phytoremediation |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Plants and other Vegetation Used: | Hybrid Poplar |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Planting Description: | Trees were planted using 12- to 18- inch dormant hardwood cuttings or live stakes. Two hybrid poplar clones (P. deltoidesx trichcarpa) and two clones of a native poplar species were installed. Large blocks of the same clone were planted together for future comparison of growth and phytoremediation capabilities. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Planting Area: | 3-4 acres | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Performance Data: | Trichloroethylene, PCE, and/or cis-dichloroethylene were found in the tissue or transpiration gas of three of the four trees examined in 2002, indicating that the tress are utilizing ground water or soil contaminated with these compounds. The largest trees at the site have done extremely well. The larger poplars within the plot had trunk diameters more than 4 inches at breast height. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Cost of the Phytotechnology Project: | Not available | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Comments: | Further monitoring is needed, but the trees have done well and are removing contaminants. This site is ideal because of excellent poplar growing conditions found in Pacific Northwest, shallow ground water, contaminant type, and low risk posed by contaminants. | Point(s) of Contact |
