Water Contaminants in Central Ohio
Each guide includes the EPA limit, typical Columbus-area levels, health effects, signs to watch for, and the most effective treatment options.
PFAS (Forever Chemicals)
Synthetic chemicals that never break down — and accumulate in your body over time.
Chloramines
Columbus switched from chlorine to chloramines in 2004 — here's what that means for your home.
Lead
There is no safe level of lead in drinking water — especially for children under 6.
Iron
The #1 water problem for Central Ohio well water users — and more common in city water than you'd think.
Nitrates
A serious risk for infants and pregnant women — especially in rural Central Ohio well water.
Microplastics
Found in virtually every water source on Earth — including Columbus tap water.
Hard Water (Calcium & Magnesium)
Columbus water averages 9–13 gpg — hard enough to cost the average family $800+ per year.
