Fig. 3: Associations between annual average county-level age-adjusted cancer incidence rate (per 100,000 persons per year) between 2016 and 2021 and detection or Maximum Contaminant Level (MCL) violation of per- and polyfluoroalkyl substances (PFAS) in drinking water based on UCMR5.

For UCMR5, all PFAS were categorized into Detected/Not Detected except for PFOS, PFOA, PFHxS, and PFNA which were categorized into above Maximum Contaminant Level or Not (4 ng/L for PFOS and PFOA and 10 ng/L for PFHxS and PFNA). The lines for statistically significant results are shown in red.
