Treatability Studies

Surfactant Flushing 

Tersus designs and optimizes surfactant systems tailored to each site’s geochemistry and NAPL composition. Treatability studies include detailed phase-behavior testing to identify the optimum salinity required to achieve ultra-low interfacial tension (IFT), enabling NAPL mobilization through capillary displacement.

Additional surfactant–groundwater and surfactant–soil interaction studies are performed to confirm that the selected surfactant system remains active under site-specific aquifer conditions. Column testing is then used to define the optimal injection strategy and to estimate surfactant requirements and post-surfactant recycled groundwater flushing volumes.

Bioremediation, Chemical Oxidation and ZVI

Decades of laboratory-to-field research have demonstrated a strong correlation between bench-scale treatability study results and successful achievement of remediation objectives in the field. Treatability studies provide a cost-effective means to evaluate multiple remedial performance variables simultaneously, optimize system design prior to full-scale implementation, and support informed decision-making.

By reducing uncertainty and improving remedial efficiency, laboratory treatability studies help facilitate stakeholder buy-in, minimize implementation risk, and ultimately lower overall remediation costs.
