Environmental and toxic tort expert witnesses
Expert class library · 2 classes
The hygienists, hydrogeologists and exposure scientists in toxic tort and contamination cases: how much of a substance a person absorbed, and how contamination moved through soil and groundwater.
Each class is defined by role and method, never by a person or a firm. Open one for what it is retained to answer, how its testimony is attacked under Rule 702, and the rulings, each read in the opinion.
Retained by either side
Task-based exposure reconstruction from work history and co-worker testimony · Use of published exposure studies and historical air monitoring
Hydrogeologist (contaminant fate and transport)Site characterization from borings, wells and sampling · Groundwater flow and contaminant transport modeling
