Raleigh Drinking Water Quality
What's Really in Your Tap Water?
Raleigh tap water has contaminants that exceed current EPA standards. At just 20 ppm (1.2 gpg), the water is pleasantly soft. Lead levels test well below the EPA action level. PFAS "forever chemicals" exceed EPA limits — the EPA recommends certified filtration. There have been 355 violations recorded over the past 3 years.

Is Raleigh Tap Water Safe to Drink?
Raleigh tap water has contaminants that exceed current EPA maximum contaminant levels.
8 contaminants were tested in Raleigh's water. 7 were detected, and 1 exceeds EPA maximum contaminant levels.
PFAS "Forever Chemicals" — PFOS at 5.45 ppt (EPA limit: 4 ppt) — exceeds the EPA maximum contaminant level. 4 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.
EPA Violations — 53 health-based EPA violations in the past 3 years across 93 water systems. Plus 302 monitoring/reporting violations.
Health-based violations mean the water exceeded a federal maximum contaminant level. This is more serious than administrative violations.
→ Consider testing your water at home and using a certified water filter until violations are resolved.
Lead — Lead (0.03 ppb) is well below the EPA action level of 15 ppb.
The data below shows test results from 93 water utilities serving 676K people in the Raleigh 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?
Raleigh has PFAS levels exceeding EPA maximum contaminant levels. The EPA suggests that NSF-certified reverse osmosis or activated carbon filters can reduce PFAS levels.

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 Raleigh 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
0.03 ppb
Raleigh 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”
1 PFAS chemical exceeds EPA maximum contaminant levels
+ 1 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.
