Kansas City Drinking Water Quality
What's Really in Your Tap Water?
Kansas City tap water meets EPA standards, though there are a few things worth knowing. At 196 ppm (11.5 gpg), the water is quite hard — you may notice mineral buildup on fixtures. Lead levels test well below the EPA action level. PFAS chemicals were detected but are within EPA limits. No violations have been recorded in the past 3 years.

Is Kansas City Tap Water Safe to Drink?
Kansas City tap water meets EPA health standards, with some contaminants worth monitoring.
9 contaminants were tested in Kansas City's water. 7 were detected — all within EPA limits.
Other Contaminants — Atrazine is at 2.67 ppb — 89% of the EPA limit (3 ppb). Within legal limits, but elevated.
One of the most widely used herbicides in the US, commonly applied to corn and sugarcane fields. Classified as a possible carcinogen. May affect the endocrine system and reproductive health.
→ Granular activated carbon filters are effective at removing atrazine.
PFAS "Forever Chemicals" — 1 PFAS compound detected, all within current EPA limits. Highest: PFBA at 5.59 ppt.
Disinfection Byproducts — 2 contaminants detected, all within EPA limits. Highest: Haloacetic Acids (HAA5) at 15 ppb (25% of EPA limit).
Inorganic Chemicals — 2 contaminants detected, all within EPA limits. Highest: Nitrate at 2.59 ppm (26% of EPA limit).
Lead — Lead (2.19 ppb) is at 15% of the EPA action level of 15 ppb.
The data below shows test results from 2 water utilities serving 515K people in the Kansas City area.
Based on publicly available data from KC Water 2024 CCR – Secondary Contaminants table: Hardness (Carbonate) 140 mg/L as CaCO3 (own sources); blended reseller water 123 mg/L (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 Kansas City water, though within current EPA limits. An activated carbon or reverse osmosis filter can further reduce PFAS exposure. With very hard water (196 ppm), a water softener can reduce scale buildup in pipes, appliances, and water heaters.

Do I Need a Water Softener?
At 196 ppm, Kansas City 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 Kansas City tap water.
Home test kits detect lead, bacteria, pesticides, and 100+ other contaminants. Results in 5-10 business days from certified labs.

90th Percentile Lead Level
2.19 ppb
Kansas City 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.
