Dissolved Phase Contaminants — The part of (VOCs-hydrocarbon) contamination which has dissolved/partitioned into a body of water (In our case – groundwater and typically petroleum based compounds).
When hydrocarbon product is present in the dissolved phase in groundwater extraction wells, the contaminated groundwater must be treated. Geotech has the equipment for pump-and-treat systems. Pump and treat is a common method for cleaning up groundwater contaminated with dissolved chemicals, including industrial solvents, metals, and fuel oil.
Total Fluids Extraction – The removal/recovery of groundwater (usually contaminated with dissolved phase contaminants) along with any free phase product; such as gasoline and groundwater contaminated with gasoline that has portioned into it. Chlorinated solvents could also fall into this category.
Total fluids recovery systems generally require LNAPL/water separation which may be difficult due to emulsification. Emulsification problems can be minimized by proper pump selection.
