Surfactant-enhanced remediation utilizes surfactant's hydrophobic and hydrophilic properties to create an emulsion, which captures the NAPL
so it can be pumped out of the ground.

, and know that clients rate our service so highly.
One drawback of PRBs is that they can only remediate contaminant plumes that pass through them; they do not address dense NAPLs
(DNAPLs) or contaminated ground-water that is beyond the barrier.
One method commonly used to help identify NAPL
source zones, and source history is to analyze periodically, dissolved component concentrations in monitoring wells.
When applied through the aqueous phase, the HA quickly mobilizes the NAPL
by reducing the interfacial tension in the LNAPL-water system.

Remediation technologies based on the use of surfactants by reducing the capillary forces between the organic and aqueous phases are the most promising technique for removal of NAPL
from the subsurface.

The National Association for Printing Leadership (NAPL
), Paramus, New Jersey, USA, a commercial printing industry trade association, has issued its June "Printing Business Conditions Special Update" with indicators showing that business continued to weaken in June for commercial printers, reducing both confidence and the NAPL
Printing Business Index[c] to five-month lows.
