Litigation Support

  
Appalachia recognizes that litigation support requires proficiency in technical knowledge, refined oral and written language skills, easy-to-understand presentation materials, an understanding of applicable regulations and outstanding professional credentials.  Our in-house staff and extended network of environmental experts provide services and work products that meet these expectations.

Appalachia provides litigation support services in the form of:
  • Sensitive environmental & hydrogeologic data collection;
  • Independent review & critique of hydrogeologic and environmental documents & work products;
  • Hydrogeologic and environmental technical guidance;
  • Preparation of technical documents and exhibits; and
  • Expert Testimony.
Project Examples
  • PRP Group, NJ - Principal developer of a 3-D numerical groundwater flow model, which evaluated contaminant migration in the vicinity of a major landfill.  Principal tasks included the conceptual design, organization & input of hydrogeologic/environmental data via GIS and model calibration/verification using the modeling software, MODFLOW.  The modeling results were presented before multiple PRP groups and the NJDEP and resulted in the settlement of a $150 million dollar lawsuit that had spanned 20 years.
  • Industrial Site, IL. - Supervised the field collection of groundwater quality data in support of a class action lawsuit, reviewed/provided comment on a 3-D numerical groundwater flow and contaminant transport model and co-developed a regional 3-D numerical groundwater flow model for use in litigation.
  • Former Industrial Site, NY - Characterized/delineated historic asphalt and coal tar discharges for ensuing litigation by means of collecting product samples for forensic analyses.
  • Commercial Property, NJ - Provided an independent critique of a mounding analysis that utilized numerical groundwater modeling software (MODFLOW).
  • Manufactured Gas Plant, NY - Provided a critique and comment on a numerical groundwater flow model (MODFLOW) that evaluated the potential for MGP contaminant impacts to nearby public supply wells.  The exercise resulted in major modifications to the model, its interpretation and conclusions regarding contaminant impacts.
