Moderate concernPerfluorohexane sulfonate (PFHXS) detected at 2.8 ppt, 2800x above the EWG health guideline of 0.001 ppt.
Haloacetic acids (HAA9) significantly above health guideline
Moderate concernHaloacetic acids (HAA9) detected at 34.6 ppb, 577x above the EWG health guideline of 0.06 ppb.
Haloacetic acids (HAA5) significantly above health guideline
Moderate concernHaloacetic acids (HAA5) detected at 35.4 ppb, 354x above the EWG health guideline of 0.1 ppb.
Arsenic detected
Moderate concernArsenic detected at 0.5 ppb.
