Litigation support regarding the fate, transport, and time period of per- and polyfluoroalkyl substances (PFAS)

Supporting PFAS Fate and Transport Litigation

Challenge:

Antea Group was retained to provide expert testimony regarding the fate, transport, and time period of per- and polyfluoroalkyl substances (PFAS) in the groundwater at a confidential site.

Solution:

Our expert submitted his expert report and was then deposed. In preparing the expert report, Antea Group performed or directed surface water and sediment sampling and analysis for PFAS in August 2017 to augment the existing 10-years’ worth of data. 

An innovative data management and assessment solution using Python programming and Mann-Kendall and Theil-Sen analyses was incorporated into the project. The PFAS trends over time for each well were assessed using these statistical methods. Due to the number of wells in the subject area (>2,000 wells, 3 compounds each), a Python script was created to automate the generation of tables and graphs for depicting the results.

Result:

Our detailed expert report, coupled with our data management and assessment solution, aided the client in getting the case settled the morning of jury selection, thus avoiding a trial.
