Charlotte Drinking Water Quality
What's Really in Your Tap Water?
Charlotte tap water meets EPA standards, though there are a few things worth knowing. At just 13 ppm (0.8 gpg), the water is pleasantly soft. Lead levels test well below the EPA action level. PFAS chemicals were detected but are within EPA limits. There have been 13 violations recorded over the past 3 years.

Is Charlotte Tap Water Safe to Drink?
Charlotte tap water meets EPA health standards, with some contaminants worth monitoring.
10 contaminants were tested in Charlotte's water. 8 were detected — all within EPA limits.
Disinfection Byproducts — Trihalomethanes (TTHM) is at 64 ppb — 80% of the EPA limit (80 ppb). Within legal limits, but elevated.
A group of chemicals (chloroform, bromoform, and others) that form when chlorine used to disinfect water reacts with natural organic matter. According to the EPA, long-term exposure is linked to increased risk of bladder cancer and liver, kidney, and central nervous system problems.
→ An activated carbon filter (pitcher, faucet-mount, or whole-house) effectively reduces trihalomethanes.
PFAS "Forever Chemicals" — 2 PFAS compounds detected, all within current EPA limits. Highest: PFBA at 7.5 ppt.
Metals — 1 contaminant detected, all within EPA limits. Highest: Chromium (VI) at 0.1 ppb.
Inorganic Chemicals — 1 contaminant detected, all within EPA limits. Highest: Fluoride at 0.74 ppm (19% of EPA limit).
The data below shows test results from 21 water utilities serving 1.2M people in the Charlotte area.
Based on publicly available data from Charlotte Water 2024 Water Quality Report (2024). 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?
PFAS chemicals were detected in Charlotte water, though within current EPA limits. An activated carbon or reverse osmosis filter can further reduce PFAS exposure.

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 Charlotte 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 ppb
Charlotte 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”
PFAS detected but within current EPA limits
PFAS are synthetic chemicals that don't break down in the environment. Levels are within current EPA maximum contaminant levels.
