Surfactant Enhanced Aquifer Remediation (SEAR), in its most basic form, could thus be considered a chemical enhancement to pump and treat. A chemical solution is pumped across a contaminated zone by introduction at an injection point and removal from an extraction point.

In summary, surfactant-enhanced pump-and-treat remediation is effective for DNAPL chemicals with relatively low aqueous solubilities, but requires surfactant reuse to be economical.

Surfactant-enhanced aquifer remediation (SEAR) is widely considered a promising technique to remediate dense nonaqueous phase liquid (DNAPL) contaminations in-situ.

The costs of a SEAR remediation are important and depend mostly on the setup of the remediation.

Metadata Show full item record. Abstract. Surfactant enhanced recovery is used most often where the groundwater is contaminated by dense nonaqueous phase liquids (DNAPLs).

These dense compounds, such as trichloroethylene (TCE), sink in groundwater because they are heavier than water. They then act as a continuous source for contaminant plumes that can stretch for miles within an aquifer.

Surfactant-Enhanced Remediation Surfactants, or surface-active agents, are chemical compounds that have the potential to alter the properties of fluid interfaces. Surfactant usage dates back to the s when sulfonate surfactants attained widespread use for enhanced oil recovery efforts.

Use in environmental applications dates to the s. DNAPL recovery, due to their inability to mobilize entrapped solvents and the generally low solubility of these organic liquids.

The ineffectiveness of existing remedial technologies for treatment has created the need for alternative remediation approaches. One such technology, surfactant enhanced.
