Water Quality Summary
Tap water quality in Dallas, Texas (75214) receives an overall grade of F (Failing) with a score of 21 out of 100, based on analysis of EPA compliance data, contaminant testing, and violation history. This is 48 points below the Texas state average of 68. Compared to the national average (75), this area scores significantly lower. The area is served by 6 water systems providing water to approximately 1,357,754 people, using surface water sources. Testing has found elevated levels of Lead that warrant attention. Notably, 2 PFAS compounds exceed EPA limits — a significant concern given the persistent nature of these chemicals. Over the past 5 years, water systems here have accumulated 127 violations, including 7 health-based violations.
A score of 21/100 indicates serious water quality failures in Dallas, TX. The water system has significant violations, contaminant exceedances, or enforcement actions. Residents should strongly consider using a certified water filtration system for drinking and cooking water, requesting their utility's latest test results, and potentially having their water independently tested.
Health Information
Lead is a toxic metal that can leach from aging pipes and plumbing fixtures.
Even low levels of lead exposure can cause developmental delays in children, kidney damage, and cardiovascular effects in adults. The EPA action level is 15 ppb, but health experts recommend no safe level of lead in drinking water.
Lead enters water primarily through corrosion of lead service lines, lead solder, and brass fixtures — especially in homes built before 1986.
If lead is detected above 1 ppb, consider using a certified lead-removal filter (NSF/ANSI 53) for drinking and cooking water. Run cold water for 30 seconds before use if water has been sitting in pipes.
Common Questions
Tap water in Dallas, Texas receives a grade of F (Failing) with a score of 21/100. This indicates significant water quality concerns based on violation history, contaminant levels, or enforcement actions. We recommend reviewing the specific contaminants detected below and considering a certified water filter.
ZIP code 75214 is served by 6 water systems using surface water sources, providing water to approximately 1,357,754 people. Surface water systems are more susceptible to contamination from agricultural runoff, industrial discharge, and weather events, but typically undergo more extensive treatment including filtration and disinfection.
Yes — lead levels in Dallas, Texas are 20.0 ppb, which exceeds the EPA action level of 15 ppb. This is a serious concern. We strongly recommend using a certified lead-removal filter for all drinking and cooking water, and having your water independently tested.
