For those projects requiring rapid cleanup,
location of an unknown contaminant source area, or for
quickly reducing uncertainty (brownfields sites),
conventional assessment methods may not produce
satisfactory plume definition, and more sophisticated
techniques are now commonly needed. For those sites, Duncklee and Dunham utilizes newer methods such as
membrane interface probe (MIP) techniques, x-ray
fluorescence (XRF), field test kits, and field gas
chromatography services to map soil or ground water
plumes in more detail. Most of these methods provide
real time data so that our personnel can adjust the
site sampling plan while in the field.
MIP methods enable ground water plumes to be mapped in
real time with much greater accuracy, including the
locating of dense non-aqueous phase liquid (DNAPL)
zones. This allows for the more accurate placement of
additional monitoring wells in both horizontal and
vertical directions.
Just as important on many projects, MIP methods show
the best target zones for the placement of in-situ
chemical oxidants. For sites requiring a high degree
of plume definition, such as an in-situ chemical
oxidation project, MIP methods will provide real-time
data in three dimensions that allow for quicker and
more cost effective remediation.
Furthermore, using MIP and other innovative methods,
we are able to deliver the remediation chemicals to
specific contaminated zones allowing more cleanup with
less expenditures for remediation chemicals.
