Comparison of PFAS in dogs’ drinking well or bottled water. Results of (A) unsupervised hierarchical clustering and (B) principal component analysis of Log10(X + 1) transformed serum PFAS concentrations from dogs given bottled water and well water. (C) Difference between mean Log10(X + 1) transformed serum PFAS concentrations with 95% confidence intervals, well–bottled (fluoroethers, green; sulfonics, purple; carboxylics, orange; ****p ≤ 0.0001). Dogs given well water (n = 14) compared to bottled water (n = 17).
