Catherine Boston, MPH

Principal Scientist Risk Assessor

Ms. Boston combines her background in geology with her human health risk assessment and statistical expertise to provide multi-disciplinary support for remedial investigations and in environmental litigation. She holds a B.A. from Colgate University, and a Master of Public Health (MPH) degree from Boston University with a focus on Environmental Risk Assessment and Toxicology, where her research has revolved around per- and polyfluoroalkyl substances (PFAS). Ms. Boston’s areas of expertise in toxicology and human health risk include emerging contaminants, quantitative risk assessment, exposure assessments, and toxicological evaluations. Ms. Boston conducts quantitative human health risk assessments and negotiates with regulatory agencies in support of remedial investigations at contaminated properties across the United States. In an environmental litigation context, Ms. Boston has evaluated compliance with the National Contingency Plan for cost recovery (including evaluations of the necessity and appropriateness of response action costs), has performed complex allocations of costs at landfills, sediment sites, and at other large industrial sites, and has performed state of knowledge assessments.

representative projects

Former Dry Cleaning Facility, Oklahoma: Provided expert opinions regarding the nature and extent of contamination, and causation of a release of tetrachloroethylene (PCE) at a former dry cleaning facility in Oklahoma. Expert opinions supported an allocation indicating a de minimus contribution from the client. Case settled prior to depositions.


Tank Car Facility, Ohio: Completed a baseline Reasonable Maximum Exposure (RME) RAGs human health risk assessment for a 160-acre tank car maintenance facility impacted with petroleum hydrocarbons, solvents, and metals. Impacted media included soil, soil gas, and indoor air at five buildings, groundwater, and drinking water. Identified Remedial Action Objectives (RAOs) and calculated Preliminary Remedial Goals (PRGs) to inform a Feasibility Study.


Abandoned Uranium Mines, the Navajo Nation: Prepared White Paper on cleanup options for abandoned uranium mines in the Navajo Nation. Summarized the extent and status of surficial contamination arising from past uranium mining activities, and examined the human health risks uranium contamination poses to the people of the Navajo Nation.


Chemical Manufacturing Facility, New Jersey: Evaluated the transport pathways from a large chemical manufacturing plant to the Lower Passaic River, and variability of contributions from various owners/operators. Assessed the historical chemical manufacturing process, and evaluated the effectiveness, implementability, and costs of historical large-scale sediment dredging sites. Case settled prior to trial.


Former Iron Smelter, California: Performed fingerprinting statistical analysis using trace metals signatures of electric arc furnace fugitive emissions (via principal component analysis). Determined arsenic and lead contamination associated with operation of a former steel smelter migrated to neighboring school property.
