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.

Latest News at Duncklee & Dunham


June 2008

Salisbury NC Site - A variance from NC 2L ground water standards has been approved by NC DENR for this project. Very few variance requests have been approved by the agency over the years. Duncklee & Dunham designed and applied for the variance request on behalf of our client for levels of benzene and naphthalene in ground water at this industrial site.

Rocky Mount, NC Site - The excavation of chromium impacted soils is underway for a local NC project. The remediation work plan includes the use of x-ray fluorescence instrumentation to obtain real time field data on metals levels in the soils.

Research Triangle Park, NC - Dr. Bryson Trexler continues to provide services to one of the world's leading pharmaceutical companies.

Colorado, Texas, and California - Daphne Olszewski is traveling this month to perform ISO audits of several major Brownfields development projects in the western US.
