Soil and Ground Water Assessment

 

The Senior Staff has performed hundreds of soil and ground water assessment projects in 30 US States in accordance with differing State and Federal regulatory requirements.  These assessments have been performed for RCRA hazardous waste releases, federal and state-lead Superfund sites, and State lead release investigations.  RCRA services include assessment of releases caused by fires or leaks from containers, Closure Plans, Part B applications and renewal applications, characterization and disposal of drums/containers, RCRA Facility Investigations (RFI’s), Corrective Measures Studies, Interim Measures remediation, design and implementation of final remedies, and regulatory negotiations. 

Our staff has extensive experience in differing hydrogeologic environments in assessing chlorinated solvent (including 1,4-Dioxane), nutrient, petroleum hydrocarbon, MTBE, and inorganic plumes.  Standard assessment methods such as auger or air rotary and direct push drilling rigs are commonly utilized.  Other common methods include soil gas surveys, geophysical surveys, the collection of monitored natural attenuation parameters, and of course the collection of soil and ground water samples.  Conventional assessment methods typically result in ground water plume maps that show the general shape of a contaminant plume, and this is satisfactory for many sites.

Duncklee & Dunham's Jay Bennett and Bryson Trexler are using innovative techniques to develop site specific soil clean-up levels and develop a ground water variance for site metals restoration. The site is under the REC program and currently being managed on a fast track basis to accommodate expedited clean-up of soil and groundwater once plant modifications are made.

Duncklee & Dunham is preparing to implement full scale injection plan involving sodium persulfate into shallow groundwater under and adjacent to a former manufacturing building. A corrective action plan and an injection permit were submitted and approved under the Ga DEP HIS program.
