Jacksonville, FL Tap Water Quality Report
Last updated November 2026. Here is what testing has found in Jacksonville, Florida tap water, compared with health-based goals (not just the legal limits, which can be much higher). Your exact address may be served by a different system, so check your ZIP code free.
The contaminants furthest above health goals in Jacksonville tap water are Arsenic, Total trihalomethanes (TTHM) and Radium (226 + 228).
What these contaminants are
- Arsenic: A naturally occurring metal. Long-term exposure is linked to skin, bladder and lung cancer.
- Total trihalomethanes (TTHM): Disinfection byproducts that form when chlorine reacts with organic matter. Long-term exposure is linked to bladder cancer and liver and kidney effects.
- Radium (226 + 228): Naturally occurring radioactive elements in some groundwater. Raise bone cancer risk.
JEA (major grid)

How to filter Jacksonville tap water
- Chlorine and its byproducts in the shower: a 15-stage filtered shower head or universal shower filter is designed to reduce chlorine and chlorine odor where hot water turns it into steam.
- Drinking and cooking water: the 8L stainless steel gravity filter uses carbon filters, needs no plumbing or electricity, and keeps working through Florida storm outages.
- Fluoride: add post-treat fluoride filters to the gravity system.

About this data
Results come from testing and annual water quality reports that utilities file with the EPA and the Florida Department of Environmental Protection, compiled in our free water check. Health goals are the stricter of EPA health goals or California public health goals; legal limits are EPA maximum contaminant levels or action levels. Water quality can change between the treatment plant and your home, so these figures are a guide, not a test of your own tap.
