Description

This tech brief provides an overview of Surfactant-Enhanced Aquifer Remediation (SEAR) using TASK™ (Tersus Advanced Surface Kinetics) to mobilize and recover non-aqueous phase liquids (NAPL) from soil and groundwater. The document explains the science of interfacial tension reduction and middle-phase microemulsion formation, and how site-specific surfactant formulations are engineered using actual NAPL, groundwater, and soil samples to maximize recovery while minimizing surfactant usage and waste generation.
