Typical Risk Assessment projects
   
Hazardous Waste Incinerators

AMAI conducted a multi-pathway risk assessment in order to assess risks to human health and the environment associated with emissions from hazardous waste incinerators operated by a pharmaceutical manufacturing facility. Major components of the risk assessment included:

  • Identification of constituents of concern based on waste feed analysis and stack testing of incinerator emissions
  • Computer modeling of dispersion and wet/dry deposition of stack emissions
  • Quantification of carcinogenic risks and non-carcinogenic hazards to human health due to direct and indirect exposure to constituents of concern
 

USEPA approved AMAI's finding that the incinerator emissions do not pose an unacceptable risk to human health or the environment.

Baseline Risk Assessment

AMAI is implementing a multi-media baseline risk assessment at a petroleum refinery RCRA Corrective Action site to support decisions regarding the need for site remediation.

 
  • A Conceptual Site Model was developed based on sources of releases, release mechanisms, contaminant fate and transport, exposure pathways and potential human health and ecological receptors
  • Transport pathways and cross-media transfer of contaminants through soil, groundwater, surface water, sediment, air and food chain are considered

Risks and hazards will be quantified to evaluate the need for remediation at the various areas within the site. Site-specific media cleanup standards will be developed as needed utilizing chemical-specific toxicity information, measured contaminant exposure levels, and levels predicted through contaminant fate and transport models.
