Information

Description:

Over 600 Cottonwood trees were planted over a shallow groundwater plume in an attempt to detoxify the trichloroethylene (TCE) in a groundwater plume at a former Air Force facility. Two planting techniques were used: rooted stock about two years old, and 18 inch cuttings were installed in 48 inch trenches that were backfilled with material from the trench and amendments. Drip irrigation was installed and used for the first year. Monitoring wells were installed upgradient, downgradient, and within the tree plantations. The tree roots reached the groundwater plume by the second growing season, and increased impact on the plume each year following initial contact. The plume exhibits a seasonal depression due to transpiration by the plants. The groundwater chemistry at the site also appears to be influenced by the plants.
