Irving, Texas Water Quality at a Glance
meets standards
Is Irving Water Safe to Drink?
Generally Yes, Good Quality – Irving’s water system receives Texas’ highest “Superior” rating and generally meets federal standards. However, PFOA contamination at 4.9 ppt slightly exceeds EPA’s 4 ppt limit for this “forever chemical.” Irving gets its water from Dallas’ system, which draws from multiple surface water sources including Lakes Grapevine, Ray Hubbard, and others. The city serves over 250,000 residents with treated water that undergoes settling, filtering, and disinfection processes.
⚠️ Key Considerations for Irving Residents
- PFOA “Forever Chemical”: 4.9 ppt detected (January 2024) – exceeds EPA’s 4 ppt limit; linked to kidney cancer, testicular cancer, and other health issues
- Regional PFAS Impact: Part of Dallas-Fort Worth area where multiple water systems exceed new federal PFAS limits
- Water Source: Surface water from Dallas system – multiple lakes including Grapevine, Ray Hubbard, Ray Roberts, Tawakoni
- Treatment Process: Uses chloramines for disinfection (safer than chlorine alone), activated carbon for taste/odor control

Even Good Water Can Be Better
Your water quality report shows strong results — and that’s great news. But even in areas with high ratings, trace levels of chlorine, sediments, and microplastics can still impact the taste and overall experience.
A high-quality water filtration system can help refine what’s already good — giving your household cleaner, fresher-tasting water with every glass.
Smart Enhancements for Everyday Water:
✅ Make a good thing even better with advanced filtering
✅ Enjoy crisper taste and fewer lingering chemicals
✅ Great for coffee, tea, and cooking water too

Irving – Texas – Water Quality Report 2025: PFAS Testing, Infrastructure Concerns & Safety across your city
Irving Water Utilities provides comprehensive water services to approximately 250,000 residents across the city of Irving and surrounding areas in Dallas County. The Water Utilities Department serves more than 47,000 water account holders and is responsible for ensuring that Irving residents have access to safe and clean drinking water at a reasonable volume and cost. The State of Texas has designated Irving as a Superior Public Water System, the highest rating given by the state, which encompasses an advanced distribution network and multiple treatment partnerships that deliver safe drinking water to North Texas residents.

Frequently Asked Questions
Is Irving’s tap water safe to drink?
Irving’s tap water is generally safe to drink and meets most federal and state drinking water standards. Data gathered from ongoing testing confirms Irving’s tap water meets or exceeds most standards set by the U.S. Environmental Protection Agency, though recent testing detected PFOA at 4.9 parts per trillion, which slightly exceeds EPA’s new 4 ppt limit established in 2024.
Irving has earned the distinction of being designated as a Superior Public Water System by the State of Texas, the highest rating given by the state. Irving Water Utilities conducts thousands of tests monthly to ensure water quality, far exceeding government-required testing standards. The comprehensive treatment process through Dallas facilities incorporates multiple barriers against contaminants, ensuring generally safe drinking water delivery through Irving’s distribution system, though residents may want to consider filtration for PFAS reduction.
Why does my water sometimes taste or smell different?
Occasional taste and odor changes can occur due to several factors:
1. Disinfection process: Irving’s water is treated with chloramine (a combination of chlorine and ammonia) for disinfection, which may cause a noticeable chlorine-like taste or smell
2. Seasonal water quality changes: Natural variations in Dallas Water Utility source waters (Lakes Grapevine, Ray Hubbard, Ray Roberts, Tawakoni, and Lewisville) can affect taste, especially during heavy rainfall or drought periods
3. Home plumbing: Internal plumbing issues or infrequently used faucets can sometimes cause taste or odor concerns
If taste or odor issues persist, contact Irving Water Utilities at (972) 721-2411 for assistance. Often, running cold water for a few minutes after periods of non-use can help improve water quality from your tap.
Does Irving test for lead in its water system?
Yes, Irving conducts regular testing for lead and other contaminants as required by federal regulations:
• Corrosion control: The treatment process includes lime and iron sulfate for corrosion control, which helps prevent leaching of lead and copper from plumbing materials
• Regular monitoring: Comprehensive testing is conducted throughout the distribution system to ensure compliance with EPA lead and copper rules
• Treatment partnership: Dallas treatment facilities utilize advanced treatment processes that include corrosion inhibitors to minimize lead exposure
• Home testing: Residents concerned about lead in their home plumbing can contact Irving Water Utilities for guidance on testing options
Homes built before 1986 have a higher likelihood of containing lead components in internal plumbing, which is why residents in older homes should consider using cold water for drinking and cooking.
What are Irving’s current water restrictions?
Irving has implemented year-round water restrictions to promote conservation and ensure sustainable water use:
Time-of-Day Restrictions:
• No watering between 10 a.m. and 6 p.m. from April 1 through October 31 to minimize evaporation
Day-of-Week Schedule:
• Odd-numbered addresses: Watering permitted on Wednesdays and Saturdays
• Even-numbered addresses: Watering permitted on Thursdays and Sundays

Contaminants of Concern
Disinfection Byproducts
Source: Formed when disinfectants such as chloramine react with naturally occurring organic matter in Dallas Water Utility source waters; levels may vary seasonally based on source water conditions
Health Effects: Long-term exposure to elevated levels may increase risk of certain cancers and potentially affect liver, kidney, and central nervous system function
Current Levels: Monitored regularly throughout Irving’s distribution system with levels maintained below EPA maximum contaminant levels EPA Limits: 80 ppb for total trihalomethanes (TTHMs) and 60 ppb for haloacetic acids (HAA5)
PFAS Compounds
Source: Per- and polyfluoroalkyl substances originating from industrial processes, firefighting foams, and consumer products that can enter source waters and persist in the environment indefinitely
Health Effects: Research suggests potential concerns including impacts on immune system, thyroid function, cholesterol levels, and possible links to kidney cancer, testicular cancer, and reproductive issues
Current Status: Irving detected PFOA at 4.9 parts per trillion in January 2024, exceeding EPA’s new 4 ppt limit. Irving was among North Texas cities reporting PFAS concentrations above new EPA limits, along with Dallas, Farmers Branch, Duncanville and Flower Mound EPA Action: New federal regulations for specific PFAS compounds were finalized in 2024, requiring water systems to implement treatment if levels exceed regulatory limits by 2029
