Provided expert and litigation support for a lawsuit filed against more than two dozen defendants, including manufacturers, distributors, and retailers of perchloroethylene or PERC. The cost recovery action was filed by one of the largest public drinking water system suppliers in New York who sought damages for PCE contamination of more than 200 drinking water wells. This project involved a review of documents and preparation of a report regarding the relative contribution of defendant parties.
As the consulting expert, provided litigation support and prepared environmental Expert Report for a Civil Action lawsuit that involved groundwater and vapor exposures to chlorinated solvents in fractured bedrock, emanating from an adjacent industrial site. Careful review and additional investigation conducted on behalf of the Plaintiff identified additional exposure pathways and a new emerging mobile contaminant (1,4-dioxane) that was not previously identified by the defendant and was not being addressed by ongoing treatment by the existing pump and treat system. Participated in court-appointed mediation as an expert and negotiated settlement terms.
Consulting expert and fact witness for an insurance matter involving a class action suit against a Fortune-500 client for groundwater contamination at a former chemical manufacturing facility in New Jersey that was remediated using Electrical Resistance Heating (ERH) and Dual Phase Extraction (DPE). Provided sworn deposition.
As the LSRP, provided mediation support for over a $200 million-dollar insurance claim at several Manufactured Gas Plant (MGP) sites in New Jersey. Prepared an independent estimate of alternative remedial actions for use in settlement discussions. Participated in settlement discussions and presented alternative remedial approaches for each site.
