What This Means for Your Home

How Tampa’s Water Impacts Drinking, Skin & Appliances

1. Drinking & Cooking Water

PFAS (6.9 ppt) & Lead (4.4 ppb)

Tampa tap water scores a D+ because Hillsborough River and Floridan Aquifer blends test at 6.9 ppt PFOA/PFOS (above the 4.0 ppt EPA standard), alongside 215 mg/L (12.6 gpg) limestone hardness and 56.8 ppb TTHMs. 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.
