PFAS Exposure in Augusta Households from Diet and Drinking Water

63 participants from 18 households in Downtown Augusta, Georgia, USA provided dietary intake data and tap water samples for PFAS analysis. The dataset includes modeled dietary PFAS exposure using FDA data and analyzed water samples, with Monte Carlo simulations estimating individual intake rates. The study was authored by Sizhuang Liu and published on figshare in April 2026.

Use Cases

• Modeling individual PFAS intake rates based on Monte Carlo simulations incorporating contaminant levels, ingestion behavior, and body weight.
• Analyzing disparities in PFAS exposure risk based on sociodemographic factors like income and educational attainment.
• Evaluating compliance with EPA Maximum Contaminant Levels and draft reference doses for PFOA and PFOS.
• Developing replicable frameworks for community-based participatory research integrating environmental sampling and exposure modeling.

Strengths

• Includes data from 63 participants across 18 households, providing a community-level sample.
• Integrates multiple data sources: detailed grocery records, dietary intake data, and analyzed residential tap water samples.
• Employs Monte Carlo simulations to account for variability in contaminant levels and ingestion behavior.

Limitations

• Food samples collected from households were not analyzed due to funding limitations.
• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset's 2.4 MB size suggests a relatively small scale.
