What these numbers mean for your home
Chlorine taste and smell. PA American Water disinfects with chlorine. A whole-home carbon filter removes the taste and smell at every tap, including the shower. Whole-home filtration →
PFAS above the federal level. The highest PFAS result here, 11.1 ppt, is above EPA's federal limit of 4 ppt for PFOA and PFOS. Water systems don't have to meet that limit yet (EPA has proposed 2031). A reverse osmosis system at the kitchen sink reduces PFAS in drinking water. Reverse osmosis →
Hard water. At around 15.9 grains per gallon, expect scale on fixtures, spots on dishes and shorter water-heater life. A softener sized to your hardness and household stops it. Water softeners →
