Water Quality Summary
Tap water quality in Waco, Texas (76705) receives an overall grade of A (Excellent) with a score of 91 out of 100, based on analysis of EPA compliance data, contaminant testing, and violation history. This is 11 points above the Texas state average of 80. Compared to the national average (75), this area performs significantly better. The area is served by 8 water systems providing water to approximately 146,241 people, using groundwater and surface water sources. Testing has found elevated levels of Lead that warrant attention. PFAS testing detected 1 compound, all below the EPA final MCL values used for comparison. Over the past 5 years, water systems here have accumulated 87 violations, including 2 health-based violations.
A score of 91/100 means public water-system records for Waco, TX show relatively few concerns in the US Water Score model. This is an internal score, not an EPA safety rating, and it does not guarantee conditions at any specific tap.
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.
Copper can leach into water from copper plumbing, especially in newer homes or when water is acidic.
Short-term exposure above 1,300 ppb can cause gastrointestinal distress. Long-term exposure may cause liver or kidney damage. People with Wilson's disease are especially vulnerable.
Copper pipes, fittings, and faucets are the most common source. Corrosive (low-pH) water accelerates copper leaching.
If copper levels are elevated, flush pipes by running water for 15–30 seconds before use. Reverse osmosis and distillation systems effectively remove copper.
Common Questions
Based on public water-system records, Waco, Texas receives an internal US Water Score grade of A (Excellent) with a score of 91/100. This indicates relatively few system-level concerns in our model, but it is not an EPA safety rating and does not guarantee tap conditions inside individual homes.
ZIP code 76705 is served by 8 water systems using groundwater, surface water sources, providing water to approximately 146,241 people. Multiple source types mean your water may come from a blend of surface and underground sources.
Lead was reported at 2.79 ppb in public-system records for Waco, Texas. This is below the currently applicable EPA action level of 15 ppb, but may be above more protective health guidance; EPA's future LCRI action level is 10 ppb. Household plumbing can materially change tap-level exposure, so consider certified filtration and individual tap testing, especially where children are present.
1 PFAS compound were detected in water serving Waco, Texas, with reported values below the EPA final MCL values used by this site. This comparison is informational: federal compliance timelines and the status of some PFAS standards are still evolving. Activated carbon or reverse osmosis filters can reduce some PFAS when appropriately certified and maintained.
Water systems serving Waco, Texas have received 87 violations in the last 5 years, including 2 health-based violations. Violations can range from paperwork issues (monitoring & reporting) to serious health-based violations where contaminant levels exceeded safe limits. Review the violation details above for specifics.
Based on detected contaminants (lead, PFAS, copper), residents in Waco, Texas should consider: Reverse osmosis (RO) system — most effective for PFAS, lead, and other contaminants. Always look for filters with NSF/ANSI certification for the specific contaminants you want to remove.
