Arlington Drinking Water Quality
What's Really in Your Tap Water?
Arlington tap water has notable issues that residents should consider. With 135 ppm hardness (7.9 gpg), expect some mineral deposits over time. Lead levels test well below the EPA action level. PFAS "forever chemicals" exceed EPA limits — a water filter is strongly recommended. No violations have been recorded in the past 3 years.

Is Arlington Tap Water Safe to Drink?
Arlington tap water has significant quality concerns that may require action.
6 contaminants were tested in Arlington's water. 5 were detected, and 1 exceeds EPA limits.
PFAS "Forever Chemicals" — PFOS at 4.27 ppt (EPA limit: 4 ppt) — exceeds the EPA safety limit. 4 other PFAS compounds were also detected within limits.
A man-made "forever chemical" formerly used in Scotchgard, firefighting foam, and industrial processes. 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 (1.02 ppb) is at 7% of the EPA action level of 15 ppb.
The data below shows test results from 1 water utility serving 405K people in the Arlington area.
Do I Need a Water Filter?
Arlington has PFAS levels exceeding EPA limits. A reverse osmosis (RO) filter or NSF-certified activated carbon filter is recommended to reduce PFAS in your drinking water. With hard water (135 ppm), a water softener can reduce scale buildup in pipes, appliances, and water heaters.

Do I Need a Water Softener?
At 135 ppm, Arlington has hard water. You may notice white spots on dishes, dry skin after showering, and mineral buildup on fixtures. A water softener can help reduce these effects, though it's not strictly necessary for health — hard water is safe to drink.

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 Arlington tap water.
Home test kits detect lead, bacteria, pesticides, and 100+ other contaminants. Results in 5-10 business days from certified labs.

Arlington lead levels are well within safe limits.
Regular testing is still recommended, as lead can enter water through household plumbing.

About Lead in Drinking Water
What is Lead in Water?
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, though they emphasize there is no safe level of lead exposure.
Potential Health Effects
Developmental delays, learning difficulties, lower IQ, behavioral issues
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 limits
+ 1 more PFAS compounds detected
PFAS are synthetic chemicals that don't break down in the environment. A reverse osmosis or activated carbon filter can reduce PFAS levels.
Other Detected Contaminants
6 contaminants detected
| Contaminant | Your Water | Limit (MCL) | Status |
|---|---|---|---|
PFBA | 6.36 ppt Range: 0-8 UCMR5 - 7/8 samples detected | N/A | Safe |
PFBS | 4.08 ppt Range: 0-5.9 UCMR5 - 6/8 samples detected | N/A | Safe |
PFHXA | 4.2 ppt Range: 0-5 UCMR5 - 7/8 samples detected | N/A | Safe |
PFOA | 0 ppt Range: 0-0 ND - UCMR5 - 0/8 samples detected | 4 ppt 0 | Safe |
PFOS | 4.27 ppt Range: 0-4.6 UCMR5 - 3/8 samples detected - Max 4.6 ppt exceeds EPA MCL of 4 ppt | 4 ppt 0 | Exceeds 107% of limit |
PFPEA | 4.59 ppt Range: 0-6.5 UCMR5 - 7/8 samples detected | N/A | Safe |
MCL = Maximum Contaminant Level (EPA legal limit)
