WATER QUALITY REPORT
Jacksonville Water Quality
Yes. JEA meets all federal drinking-water standards, and independent analyses rank Jacksonville's tap water among Florida's cleanest. What homes notice is that it is hard (often 16+ grains per gallon) and carries a chlorine taste, and that a high share of the metro is on private wells that add iron and sulfur.
THE SOURCE
Where Jacksonville's water comes from
Jacksonville's water is Floridan aquifer groundwater from 130+ wells, aerated to strip sulfur before distribution. It's disinfected with chlorine, and the dominant provider, JEA, does not soften it — which is why hard to very hard water reaches your tap. About 22.4% of the metro is on private wells, which add their own iron, sulfur, and low-pH issues on top of hardness.
VERIFIED DATA
The numbers, by utility
We hold verified water-quality data for 13 community water systems across Jacksonville. Every figure is copied from that utility's own report. Open one for its full readings.

Jacksonville water questions
Is Jacksonville tap water safe to drink?
Yes. JEA meets all federal drinking-water standards, and independent analyses rank Jacksonville's tap water among Florida's cleanest. What homes notice is that it is hard (often 16+ grains per gallon) and carries a chlorine taste, and that a high share of the metro is on private wells that add iron and sulfur.
How hard is the water in Jacksonville?
Jacksonville water typically runs 7-21.7 grains per gallon, which is hard to very hard. JEA does not soften it, so scale, spots, and dry skin are common.
Does JEA soften the water?
No. JEA treats and disinfects the water with chlorine but does not remove hardness, so softening happens at the home.
What's in Jacksonville tap water besides hardness?
The most common issues are: Very hard water in much of the system (up to ~21.7 grains per gallon); Hydrogen sulfide (rotten-egg) odor, stripped at JEA plants, but common in untreated wells; Chlorine taste and odor; A high share of homes on private wells with iron, sulfur, and low pH.
