Innovations in Groundwater Remediation1
Center for Natural Resources2Abstract
This fact sheet briefly describes methods to remediate contaminated groundwater and related advantages. It lists UF faculty, project supporters and collaborators, and other related Web Sites and contacts.
Innovative research conducted by a University of Florida (UF) faculty team offers an efficient and less costly approach to remediating contaminated groundwater.
The traditional pump-and-treat method involves flushing with water to dissolve and extract pollutants. Because contaminants do not dissolve readily in water, this procedure requires using large quantities of water over several decades.
The UF approach is based on injecting mixtures of water, alcohols (co-solvents) and/or detergents (surfactants) into contaminated areas. These additives dissolve nearly 1,000 to 10,000 times more of the contaminant, thereby drastically reducing the clean-up time. The flushing agents dissolve the pollutants, which are then "flushed" out for disposal or treatment above ground.
The relatively high cost of water-only remediation leads many companies to stall restoration, accepting less expensive legal fees incurred from delaying cleanup efforts. The UF groundwater remediation method could make site restoration more economically feasible.
