Tampa Drinking Water Quality
What's Really in Your Tap Water?
Tampa tap water has contaminants that exceed current EPA standards. At 190 ppm (11.1 gpg), the water is quite hard — you may notice mineral buildup on fixtures. Lead levels test well below the EPA action level. PFAS "forever chemicals" exceed EPA limits — the EPA recommends certified filtration. There have been 83 violations recorded over the past 3 years.

Is Tampa Tap Water Safe to Drink?
Tampa tap water has contaminants that exceed current EPA maximum contaminant levels.
8 contaminants were tested in Tampa's water. 8 were detected, and 2 exceed EPA maximum contaminant levels.
PFAS "Forever Chemicals" — PFOS at 5.42 ppt (EPA limit: 4 ppt), PFOA at 4.5 ppt (EPA limit: 4 ppt) — exceed the EPA maximum contaminant level. 6 other PFAS compounds were also detected within limits.
A man-made "forever chemical" formerly used in Scotchgard, firefighting foam, and industrial processes. According to the EPA, associated with increased cholesterol, thyroid disease, immune system suppression, and certain cancers.
→ A reverse osmosis (RO) or NSF-certified activated carbon filter can reduce PFOS by 90% or more.
Lead — Lead (0.75 ppb) is at 5% of the EPA action level of 15 ppb.
The data below shows test results from 47 water utilities serving 1.0M people in the Tampa area.
Based on publicly available data from TODO: Add from CCR. Water quality can vary by location, building plumbing, and over time. This assessment reflects compliance with federal EPA standards and is not medical advice.
Do I Need a Water Filter?
Tampa has PFAS levels exceeding EPA maximum contaminant levels. The EPA suggests that NSF-certified reverse osmosis or activated carbon filters can reduce PFAS levels. With very hard water (190 ppm), a water softener can reduce scale buildup in pipes, appliances, and water heaters.

Do I Need a Water Softener?
At 190 ppm, Tampa has very hard water. A water softener can help prevent scale buildup in water heaters, dishwashers, and pipes. According to the Water Quality Research Foundation, hard water can reduce appliance efficiency and increase energy costs. A whole-house water softener or salt-free conditioner can help.

Your pipes tell a different story
The data above shows what leaves the treatment plant—not what comes out of your faucet. Old pipes, lead solder, and building plumbing can add contaminants the city never tests for. Know exactly what's in your Tampa tap water.
Home test kits detect lead, bacteria, pesticides, and 100+ other contaminants. Results in 5-10 business days from certified labs.

Lead Test Results
90th Percentile Lead Level
0.75 ppb
Tampa lead levels are well below the EPA action level.
Regular testing is still recommended, as lead can enter water through household plumbing.

About Lead in Drinking Water
What is Lead in Water?
According to the EPA, lead is a toxic metal that can dissolve into drinking water from older pipes, solder, and fixtures. It's invisible, tasteless, and odorless, making testing the only way to detect it. The EPA has set an action level of 15 ppb and states there is no safe level of lead exposure.
Potential Health Effects
According to the CDC: developmental delays, learning difficulties, lower IQ, behavioral issues
According to the EPA: high blood pressure, kidney damage, reproductive issues
How to Reduce Exposure
- •Run water for 30 seconds to 2 minutes before drinking, especially in the morning
- •Use cold water for cooking and drinking (hot water dissolves more lead)
- •Install a NSF-certified filter designed to remove lead
- •Test your water, especially if your home was built before 1986
PFAS “Forever Chemicals”
2 PFAS chemicals exceed EPA maximum contaminant levels
+ 4 more PFAS compounds detected
PFAS are synthetic chemicals that don't break down in the environment. The EPA suggests that certified reverse osmosis or activated carbon filters can reduce PFAS levels.
