Moderate concernHaloacetic acids (HAA9) detected at 25.1 ppb, 419x above the EWG health guideline of 0.06 ppb.
Haloacetic acids (HAA5) significantly above health guideline
Moderate concernHaloacetic acids (HAA5) detected at 37.4 ppb, 374x above the EWG health guideline of 0.1 ppb.
Total trihalomethanes (TTHMs) significantly above health guideline
Moderate concernTotal trihalomethanes (TTHMs) detected at 46.6 ppb, 311x above the EWG health guideline of 0.15 ppb.
