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

    Groundwater remediation is the process that is used to treat polluted groundwater by removing the pollutants or converting them into harmless products. Groundwater is water present below the ground surface that saturates the pore space in the subsurface. Globally, between 25 per cent and 40 per cent of the world's drinking water is drawn from boreholes and dug wells.

The specific requirements or preferences of your reviewing publisher, classroom teacher, institution or organization should be applied. 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.

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.
