Water Quality Summary
Tap water quality in Payson, Arizona (85541) receives an overall grade of C (Mixed record-based signals) with a score of 69 out of 100, based on analysis of EPA compliance data, contaminant testing, and violation history. This is roughly in line with the Arizona state average of 72. The area is served by 26 water systems providing water to approximately 17,682 people, using groundwater and surface water sources. Testing has found elevated levels of Lead that warrant attention. Notably, 3 PFAS compounds exceed the EPA final MCL value used for comparison — a significant concern given the persistent nature of these chemicals. Over the past 5 years, water systems here have accumulated 231 violations, including 17 health-based violations.
A score of 69/100 indicates fair performance in the US Water Score model for Payson, AZ. The records show noteworthy concerns, such as elevated contaminant levels, violation history, or both. Review the detailed contaminant data and official utility reports before making decisions.
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
Payson, Arizona receives an internal US Water Score grade of C (Fair) with a score of 69/100. Our model found some system-level concerns, such as violation history or elevated contaminant levels. Review your utility's Consumer Confidence Report and consult a qualified professional for household-specific health questions.
ZIP code 85541 is served by 26 water systems using groundwater, surface water sources, providing water to approximately 17,682 people. Multiple source types mean your water may come from a blend of surface and underground sources.
Lead was reported at 13.0 ppb in public-system records for Payson, Arizona. 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.
Yes — 9 PFAS compounds were detected in records associated with water serving Payson, Arizona, and 3 results exceeded the numerical EPA MCL value used for comparison. UCMR5 occurrence results alone are not a regulatory compliance determination. PFAS rules and compliance timelines are evolving; verify current information with the utility and EPA.
Water systems serving Payson, Arizona have received 231 violations in the last 5 years, including 17 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 Payson, Arizona 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.
