Duncklee & Dunham is currently managing three sites in compliance with the procedures in the NC DENR Registered Environmental Consultant (REC) program, with several others expected to begin in late 2008 and early 2009.

Duncklee & Dunham personnel offer proven superfund remedial investigation/feasibility study (RI/FS) services in addition to experience with the many now well-established State lead voluntary cleanups. 

The senior staff has authored seven major RI/FS Work Plans and RI/FS Reports.  Six of these seven work plans were for sites regulated by US EPA Region 4.  Numerous State lead sites have also been managed by the senior staff.

Mr. Dunham is conducting remedial activities at a Virginia site due to a release of liquid nitrogen fertilizer from a surface impoundment.  The site is regulated by the Virginia DEQ Voluntary Remedial Program.  Initial work involved drilling activities which included the installation of telescoping (multi-cased) ground water monitoring wells to depths up to 275 feet in limestone bedrock.  Packer testing was performed during the drilling and well installation activities to aid in determining well depths and screen intervals. 

 A major oil terminal and adjacent property on the Ohio River in Kentucky has been assessed by Mr. Dunham under the National Contingency Plan.  Unique challenges of this project include reversal of typical hydraulic gradients due to river flood stages along with complex clay and sand stratigraphy.  Duncklee & Dunham has prepared and is implementing a successful Corrective Action Plan to complete site assessment activities and effect ground water remediation across multiple release areas.  MIP assessment, air sparging, soil vapor extraction, a dewatering system combined with ex-situ chemical oxidation, bioaugmentation, and infiltration, and a  2 MGD pump and treat system are all being used in unison to expedite the cleanup and to protect a nearby municipal well field.
