Function and Performance of PHYTO-INTEGRATED™ Remediation Systems on Deep Groundwater and/or Targeted Horizons – Hydraulics and Treatment

SPEAKER: Edward G. Gatliff, Ph.D., Applied Natural Sciences, Inc.
PHYTO-INTEGRATED™ remediation systems incorporate the use of plants (primarily trees) in groundwater remediation systems that are often paired with other treatment methodologies. TreeWell® technology is a commonly employed phytoremediation methodology, typically addressing remediation of VOCs, that utilizes large-diameter (36 to 60-inch) borings excavated to the depth of the horizon of the targeted chemicals of concern (COCs). The borehole is lined to promote vertical root development and exclude non-target soil solution/groundwater and backfilled with amended soil and other treatment media. A tree or other vegetation is planted inside the lined boring. The as the vegetation grows and transpires, the TreeWell unit functions as a solar “pump” that pulls water from the targeted horizon into and through the soil/media column. This soil column functions as a “bioreactor treatment column” that treats COCs via: anaerobic mechanisms in the saturated portion aerobic mechanisms in vadose zone with the microbial rich rhizosphere (area around the roots) into the plant for in-plant degradation and/or transpiration into the atmosphere for photodegradation by sunlight.

This presentation will offer a review of case histories where TreeWell technology has been used to remediate groundwater ranging in depth from 10 to over 100 feet. The role that the TreeWell column plays in the degradation/detoxification of a wide range of contaminant types and concentrations in groundwater will be included. Case histories will cover a wide range of hydrogeologic conditions. Predictive hydraulic models will be compared to actual results. Remedial results for VOCs including PCE, TCE and other chlorinated compounds (e.g. 1,4-Dioxane, CCl4, Chlorobenzene) as well as Petroleum Hydrocarbons will also be discussed.

Dr. Edward Gatliff earned his B.S. in Agriculture from The Ohio State University and his Ph.D. in Agronomy from the University of Nebraska-Lincoln. He has over 39 years of professional experience and, through his understanding of vegetation and agronomic principles, has been applying phytoremediation related technologies to successfully remediate contaminated soil and groundwater since 1987.

As founder and president of Applied Natural Sciences, Inc., Dr. Gatliff developed a PHYTO-INTEGRATED™ remediation system approach, known as the TreeMediation® program, whereby trees and other vegetation are utilized in remediation systems that provide hydraulic and remedial effects on shallow and deep soil and groundwater. He has pioneered and patented several PHYTO-INTEGRATED™ systems including the TreeWell ® technology whereby trees extract groundwater from specific horizons of an aquifer 40 or more feet deep. His company, Applied Natural Sciences, was started in 1993 and for 24 years has provided PHYTO-INTEGRATED™ remediation system design and implementation services at over 70 sites across the U.S., Canada, Chile, and Europe.
