Sites impacted with Light Non-Aqueous Phase Liquids (LNAPL), which include petroleum hydrocarbons (i.e. BTEX, gasoline, Diesel, PAH, Motor Oil to Bunker-C), and Dense Non-Aqueous Phase Liquids (DNAPL), which include chlorinated solvents (i.e. PCB, TCE, PCE, and VC), are associated with very lengthy and very costly site remediation, with many taking greater than 20 to 30 years, costing owners millions of dollars.

This presentation will explain the fundamental Hydro-Geo-Chemical factors which negatively impact traditional in-situ LNAPL and DNAPL (NAPL) remediation, and some innovative proven methods to overcome the limitations of: sorption, agglomeration, interfacial tension, pathway interference, among others, to improve the most forms of physical, chemical, and/or biological NAPL remediation, with significantly time and costs savings.

The presentation will be visually driven, with graphs, and images, include animations, and client generated case studies, to support above narrative, and how these environmental consultants, and environmental contractors, realized more sustainable site closure, compared to their peers.
