West Palm Beach, FL Tap Water Quality Report
Last updated November 2026. Here is what testing has found in West Palm Beach, 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 West Palm Beach tap water are PFOA (a PFAS 'forever chemical'), Total trihalomethanes (TTHM) and Haloacetic acids (HAA5).
What these contaminants are
- PFOA (a PFAS 'forever chemical'): A PFAS 'forever chemical' that builds up in the body. Linked to kidney and testicular cancer. EPA's new legal limit is 4 ppt.
- 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.
- Haloacetic acids (HAA5): Another group of chlorine disinfection byproducts. Long-term exposure above EPA limits is linked to higher cancer risk.

How to filter West Palm Beach 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.
