Jim Linton, Chad Drummond to Present Innovative Florida Phytoremediation Project

Jim Linton, a senior environmental scientist, and Chad Drummond, P.E., D.WRE, a senior environmental engineer, both Geosyntec Associates based in Florida, will discuss the use of plants to remediate contaminated groundwater during an industry conference on September 12.

Their presentation "1,4-Dioxane in a Shallow Florida Aquifer: Engineered Phytoremediation as a Solution" will be delivered at the 2013 Annual Meeting of the Florida Association of Environmental Professionals (FAEP). Geosyntec is proud to be a Silver Sponsor of the event.

The presentation begins at 1:40 p.m. at the DoubleTree Hotel - Universal Orlando, 5780 Major Blvd. Pre-registration for the meeting is required.

Earlier this year, Geosyntec implemented an innovative phytoremediation strategy at a former manufacturing facility in Sarasota, Florida. Groundwater at the site is impacted with elevated levels of chlorinated solvents, 1,4-dioxane, and arsenic.

In the presentation, Mr. Linton and Mr. Drummond will describe how the team planted a zone of trees above the impacted area near the factory site. The interaction of the root systems with the groundwater at the site now controls the flow of the contaminant plume. The roots also extract and degrade contaminants through normal photosynthesis.

The goal is to use the trees to replace a mechanical remediation solution at the site that costs more than $300,000 to operate each year. By comparison, operation and maintenance costs of the phytoremediation system are expected to be limited to weed control, the annual application of fertilizer, and similar landscape maintenance activities.

Mr. Linton has more than 25 years of experience in site assessment and remediation. He specializes in phytoremediation as well as biological population studies, wetland restoration, and regulatory compliance. He frequently consults for clients in the pesticide, electronics, and aerospace industries. Mr. Drummond is a senior practitioner in water resources and environmental engineering and specializes in numerical modeling.
