Moderate concernPerfluorohexane sulfonate (PFHXS) detected at 7.7 ppt, 7700x above the EWG health guideline of 0.001 ppt.
Haloacetic acids (HAA9) significantly above health guideline
Moderate concernHaloacetic acids (HAA9) detected at 21.4 ppb, 356x above the EWG health guideline of 0.06 ppb.
Haloacetic acids (HAA5) significantly above health guideline
Moderate concernHaloacetic acids (HAA5) detected at 20.3 ppb, 203x above the EWG health guideline of 0.1 ppb.
Arsenic detected
Moderate concernArsenic detected at 0.7 ppb.
