| Project Name: | Phytoextraction at Green Island and Pachena Point in British Columbia, Canada | |||||||||||||||||||||||||||||||
| Site History and Background: | The Canadian Coast Guard is responsible for the management of 27 remote lightstation facilities on Canada's Pacific coast. Historical practices such as sandblasting of metal based paint and incineration of waste have resulted in widespread metals contamination. The sites span 27,000 km of rugged shoreline and access is limited to helicopter. The cost and logistics of removing soil with elevated metals is prohibitive. Pilot scale field trials were established at two lightstations. | |||||||||||||||||||||||||||||||
| Scale: | Pilot/Field Demonstration | |||||||||||||||||||||||||||||||
| Project Status: | Ongoing | |||||||||||||||||||||||||||||||
| Project Start Date: | June 2002 | |||||||||||||||||||||||||||||||
| Media Treated: |

| Contaminants Treated: |
| |||||||||||||||||||||||||||||||
| Phytotechnology Mechanism(s): | Phytoremediation Phytoextraction |
|||||||||||||||||||||||||||||||
| Plants and other Vegetation Used: | Indian Mustard Sunflower Pea |
|||||||||||||||||||||||||||||||
| Planting Description: | Six plots were constructed and lined with polypropylene and geotextile. Twelve cubic meters of contaminated soil was hand excavated and transferred to the treatment plots. Three plant species were selected: "Pisum sativum" (pea), "Brassica juncea" (Indian Mustard), and "Helianthus annus" (sunflower). The Indian Mustard was seeded directly into the plots, while the pea and sunflower were grown in a greenhouse and planted as seedlings. Chelators (EDTA and citric acid) were added 8 weeks after planting. | |||||||||||||||||||||||||||||||
| Climate: | The northern site, Green Island, is at 54 degrees latitude. The southern site, Pachena Point, is at 49 degrees latitude. | |||||||||||||||||||||||||||||||
| Performance Data: | Not available | |||||||||||||||||||||||||||||||
| Cost of the Phytotechnology Project: | Not available | |||||||||||||||||||||||||||||||
| Comments: | Biomass production was greater than expected, even with the high winds and rainfall typical of these sites. Plant growth does not appear to be the limiting factor in this field trial. | Point(s) of Contact |
