What This Means for Your Home

How Charlotte’s Water Impacts Drinking, Skin & Appliances

1. Drinking & Cooking Water

PFAS (4.4 ppt) & Lead (2.6 ppb)

Charlotte tap water earns a C+ grade: Catawba River water is naturally soft (2.1 gpg), but UCMR5 testing detected 4.4 ppt combined PFOA/PFOS (above the 4.0 ppt EPA limit) alongside 51.4 ppb total trihalomethanes. Boiling tap water concentrates PFAS and lead rather than removing them. Installing an NSF/ANSI 58 tankless reverse osmosis system under your kitchen sink strips 99.4% of PFOA, PFOS, lead, chromium-6, and dissolved solids right at the tap.
