Surfactant Enhanced Aquifer Remediation (SURFAC®)

SURFAC® is EcoVac Services’ patented process combining the elements of dual phase/ multi phase extraction (DPE/MPE) with surfactant injection.  Nick Athens, co-owner of EcoVac Services, building upon the Enhanced Fluid Recovery (EFR®) technology invented and developed by co-owner David M. Goodrich, developed a patent relating surfactant enhanced aquifer remediation with DPE/MPE.

This technology targets sites with light non-aqueous phase liquids (LNAPLs), dense non-aqueous phase liquids (DNAPLs), and/or high concentrations of their dissolved constituents. This surfactant enhanced aquifer remediation (SEARTM) approach incorporates the use of non-ionic, non-toxic and biodegradable proprietary surfactants to mobilize and/or solubilize LNAPL or DNAPL, which is subsequently “captured” by DPE/MPE. SURFAC® typically requires 80% to 95% less remediation time than traditional technologies while  simultaneously reducing the carbon footprint--and energy consumption--by approximately 75% as compared to traditional surfactant enhanced aquifer remediation (SEARTM) approaches.

EcoVac Services has become the leading provider of surfactant remediation services in the United States, having completed over 100 SURFAC® (surfactant enhanced aquifer remediation) projects. Removal of NAPL (LNAPL and DNAPL) utilizing our patented SURFAC® process  has provided a cost cutting, quick and effective remediation process for our many satisfied customers.
