Challenge. Determine and allocate the level of responsibility of numerous potentially responsible parties for remediation of a large-scale groundwater contamination plume in an industrial area.

Solution. INTERA personnel led an investigation to accurately determine the separate contributions of perfluorinated compounds (PFCs) from landfills or other sources, and develop a groundwater model to simulate the flow of PFCs in groundwater. For decades, PFCs have been used in hundreds of industrial applications and consumer products such as carpeting, clothing, upholstery, food containers, fire-suppression foam, and chrome plating. These chemicals are persistent in the environment and are resistant to degradation. Support of our client’s position consisted of reviewing environmental data, geology, and historical information regarding locations of nearby landfills, chrome plating facilities, and training facilities where fire-suppression foam was used, and utilizing that information to develop a site conceptual model of potential sources of PFCs. A groundwater model was developed to simulate the migration of PFCs from the contaminant sources to drinking water wells, and eventually to a river, in a karstic system.

Challenge. To support our client’s position in a natural resource damages case brought forth by the State of New Mexico.

Solution. INTERA provided technical and litigation support for a geologic and hydrogeologic evaluation of a Superfund site in New Mexico. Our efforts included completing an evaluation of the existing groundwater resources; assessing the groundwater-surface water interaction and the groundwater contamination caused by halogenated organics; simulating the groundwater flow and contaminant transport through the use of modeling; and completing a feasibility study to assess the most feasible and appropriate groundwater remediation approach and the associated costs. As part of our services, we prepared an expert report and provided deposition and hearing testimony in the case involving the State of New Mexico v. General Electric et al. in the U.S. District Court for the District of New Mexico.
