Dual Phase Pump & Treat
A slightly more sophisticated pump and treat solution for LNAPL utilises a dual phase system whereby the groundwater pumps are deployed at sufficient depth to recover relatively uncontaminated groundwater, pumping at a sufficient rate to create a cone off depression on the water table. A second skimmer pump is installed at the air/ water interface to skim off free product, or light non-aqueous phase liquid (LNAPL), thereby reducing the costs associated with treating large volumes of contaminated water. Once this ‘free product’ has been removed, the remaining dissolved phase contamination can be remediated via one of our other solutions.
