  1. Abbreviations: PFAS per- and polyfluoroalkyl substances, PBDE polybrominated diphenyl ethers, MDL method detection limit, IQR interquartile range
  2. Note: % machine readable indicates the percent of PFAS and PBDE concentrations in which a signal was obtained. Median, IQR, 95th Percentile, and Maximum values were calculated with PFAS and PBDE concentrations below the MDL coded as missing
