| Project Name: | Phytoremediation at Active Retail Gas Station in Ohio | |||||||||||
| Site History and Background: | Three, 10,000-gallon underground storage tanks at the site. Release to soil discovered in 1993 | |||||||||||
| Scale: | Full | |||||||||||
| Project Status: | Complete | |||||||||||

| Phytotechnology Mechanism(s): | Hydraulic Control Phytoextraction Phytovolatilization Rhizodegradation |
|||||||||||
| Plants and other Vegetation Used: | Hybrid Poplar Black Willow Maples |

| Planting Description: | A total of 58 tress were planted in two rows with 2.5 feet between the trees in a row and four feet between rows. Most of the trees planted were whips, but between every three to five whips planted, one two-year-old rooted tree was planted. Twelve feed pipes were also installed every 12.5 feet along the rows to allow for future fertilizing. Seven piezometers were also installed to allow for monitoring of ground water levels. | |||||||||||
| Planting Area: | 0.6 acres | |||||||||||
| Climate: | Temperature Range: -19 to 101F; Elevation: 833 ft; Mean annual precipitation: 38.1"; Growing season: 5/9-10/3 | |||||||||||
| O & M Requirements: | Maintenance and monitoring was performed monthly during the first growing season and every other month in later seasons. Maintenance included fertilizing, trimming of low limbs and limbs near overhead wires, and spraying for insects three times per year. Monitoring included tree inspections, measurement of tree heights and diameters, water level measurements, and quarterly ground water sampling. | |||||||||||
| Performance Data: | There was 100% tree survival through the first four growing seasons. Trees grew from a height of 2 to 3 feet to 10 to 15 feet in the first growing season and approximately 1 inch in diameter per year. Trees were planted approximately three feet below ground surface, and tree roots were observed as deep as 10 feet below ground surface three years later and extended about nine feet horizontally. A groundwater drop of 4.5 to 5.5 feet was observed in the third and fourth planted area when compared to upgradient groundwater indicating that the trees are establishing a more favorable, aerobic environment for rhizodegradation. | |||||||||||
| Cost of the Phytotechnology Project: | Design: $3,500, Installation: $12,000, Annual operations and maintenance: $8,500, Installation costs were estimated to be 60 to 80 percent lower than traditional remedial techniques, and operations and maintenance costs were estimated to be 50 to 75 percent lower. | |||||||||||
