JEA MAJOR GRID meets federal legal limits, but 2 contaminants are above the independent health goal. Legal does not mean the same as safe.
Most of Duval County draws from the Floridan and surficial aquifers, water that seeps through porous sand and limestone with little natural filtering, then is treated with chlorine or chloramine before it reaches your tap.
Total Trihalomethanes (TTHM) — chlorine byproducts, Lead (toxic metal, no safe level), Lithium (naturally occurring metal), PFPeS — a forever chemical, PFPeA — a forever chemical. The full list, with measured levels and health goals, is on this page and updates as the public record updates.
Whole home treatment addresses hardness, chlorine, chloramine, and the contaminants it is certified for; reverse osmosis at the tap addresses dissolved metals and forever chemicals. The reduction figures shown here are certified minimums for the treatment class, not brand claims. A free in home water test tells you which applies to your house.
