Mr. Paul Scott is a Senior Managing Health Scientist with 25 years of experience applying statistics, exposure assessment methods, and fate and transport modeling in the areas of environmental forensics, epidemiology, toxicology, occupational health, and human health and ecological risk assessment. He has extensive experience with environmental issues associated with hexavalent chromium, lead, polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs), and perfluorinated chemicals (PFCs), such as, perfluorooctanoic acid (PFOA).
Mr. Scott is an expert in the use of multivariate statistical methods to identify sources of chemicals in indoor dust, soil, sediment, air, surface water, biota, human serum, and groundwater.  He has applied statistical sampling design methods to design environmental and biomonitoring studies.  He is an expert in the use of various basic statistical data analysis methods for comparing and summarizing concentrations from soil, sediment, air, surface water, groundwater, and biota.  He has experience applying benchmark dose methods to both animal toxicity and epidemiology data, using logistic regression analysis and other categorical data analysis methods for evaluating epidemiology data, and general linear methods, such as ANOVA, for analyzing animal toxicity testing and sediment toxicity data.
In addition, Mr. Scott has extensive expertise conducting probabilistic and deterministic exposure assessments for metals, PFCs, VOCs, PCBs, PCDD/Fs, and PAHs at various industrial facilities. He was one of the first to develop and publish probability density functions for common exposure factors used in human health risk assessment.  He also has developed an empirical method for determining the exposure duration distribution from survey data.  In addition, he has experience performing human health risk assessments of remedial alternatives for both chemical and physical hazards as part of the remediation decision process at several environmental sites.
Mr. Scott is an expert in the application of fate and transport models to understand historical, current, and future exposure concentrations for both environmental and occupational exposure assessment. He has applied vapor emission, air dispersion, and particulate emission models in support of the risk assessment or remedial investigation of over 30 sites. He also has experience using soil-to-groundwater, analytical groundwater solute transport, and food web models. Mr. Scott has commented extensively regarding fate and transport modeling, and probabilistic exposure assessment on several proposed soil standards and proposed risk assessment guidance documents.
