Site Investigation & Remediation

Appalachia’s site investigation & remediation services include quality assessments/remediation of all types of media including:
  • Groundwater;
  • Surface water;
  • Soil;
  • Indoor/Outdoor Air and
  • River Sediments.
Appalachia also has expertise and experience with a wide variety of contaminants, including:
  • Light Non-Aqueous Phase Liquids (LNAPLs), which include compounds such as gasoline, diesel fuel, kerosene and jet fuel;
  • Dense Non-Aqueous Phase Liquids (DNAPLs), which include compounds such as coal tar and chlorinated solvents (i.e. TCE, PCE, etc.);
  • Pesticides and PCBs; and
  • Metals.
Appalachia's professionals have the skills and experience necessary to deal with all aspects of site investigation and remediation activities, including the preparation and review of proposals and bid packages; preparation and administration of project budgets; the scheduling, coordination and supervision of in-house personnel and sub-contractors to meet project objectives; the evaluation and interpretation of environmental data; the reporting of investigation/remediation results and for serving as a liaison between clients, attorneys and federal, state and local regulatory agencies.  Appalachia also has members on staff with Licensed Site Remediation Professional (LSRP) and Professional Geologist (PG) registrations.

Project Examples
  • Former Manufactured Gas Plant - Project involved the remedial investigation and remedial action of mobile and immobile coal tar (DNAPL) from a former MGP with a $1,000,000/year budget.  Investigations/remedial methods included:  injection well and recovery trench installation completed in an expedited manner using innovative methodologies to accommodate the construction schedule of commercial buildings, river sediment investigation using vibracores to assess background sediment quality and to delineate the horizontal/vertical extent of site-related coal tar impacts and bedrock delineation using geophysical and packer tests to evaluate fracture zones in hydraulic communication with coal tar impacted bedrock.
  • Commercial/Residential Developer - Strategic environmental planning for a major development involving multiple properties with environmental impacts of petroleum-related and chlorinated compounds in soil and groundwater. Managed personnel conducting preliminary assessments, prepared the site investigation workplan, proposed plan to consolidate properties for remedial investigation/remedial action as well as the submittal of combined documents for review by the regulatory agency to expedite the construction schedule.
