Exposure, Odor and Risk Assessment

Over a more than 25 year period, the principals of CPF have conducted hundreds of Human Health Risk, Ecological Risk and Odor Assessments for waste sites and other sources of chemical releases to outdoor air, indoor air, surface water and groundwater. We performed one of the first multiple chemical, multiple pathway risk analyses for a stationary air emission source, and conducted site-specific Monte Carlo simulations and ecological risk assessments as early as the mid-1980s for dozens of waste sites and combustion sources. Recently, we have developed integrated risk assessment/risk management tools to aid our clients in environmental decision-making.

CPF scientists have also been at the forefront of odor assessment for many years. We recognize that odors associated with manufacturing operations, waste management activities, or residual management operations are often the most significant contact between an organization and the surrounding community. Human perception of odor is complex, involving chemical, physiological, and psychological components. This complexity means that the release of even small quantities of odorants can sensitize the community to the potential for toxicant exposure and trigger health, nuisance or property damage complaints.

CPF scientists apply innovative applications of traditional tools such as air quality analyses, community epidemiology studies and sophisticated exposure modeling to delineate and often solve odor-related issues.

Our comprehensive services include:

  • Unparalleled expertise in addressing all aspects of human health, ecological, and probabilistic risk analysis in the environment and workplace
  • In-depth knowledge of and applied experience with regulatory risk assessment methods throughout North America and Europe
  • Excellence in chemical fate and transport analyses includes the measurement and modeling of chemical transport in soil, groundwater, air, and into buildings as well as the transformation and degradation of chemicals in environmental media
  • Application of environmental fate evaluations in development of natural attenuation, renovation, and bioremediation remedies.
  • Delineation and resolution of odor-related issues by applying traditional and innovative tools such as air quality analyses, community epidemiology studies and sophisticated exposure modeling
  • Development and application of methodologies that can distinguish between health effects and quality of life impacts associated with exposure to odorants
