Duncklee & Dunham conducted an extensive high-resolution site assessment to determine the extent and magnitude of a dense non-aqueous phase liquid (DNAPL) beneath a former wastewater pond that was impacted with chlorinated solvents.  The results of this assessment showed the extent of the DNAPL was concentrated in a relatively small area and was extractable.  Therefore, we designed a DNAPL recovery system that limits the amount of dissolved-phase contaminants recovered and maximizes DNAPL recovery rates.  To reduce overall costs for supplying power to this remote location, we designed the system to be solar-powered, which allows the system to operate independent of an outside power source.  The system is equipped with a control panel that allows our personnel to adjust the extraction rates to match the amount of DNAPL able to be recovered from the underlying formation over time.  To date, this system has successfully removed over 50 gallons of pure DNAPL from the underlying surficial aquifer and continues to operate today.  Contact our office for more information about this system or to consult with one of our professionals to discuss how we may be of service to you.
