1. Source Water Type Shapes What to Expect
The public water system serving Flagstaff, Coconino County, primarily draws from surface water sources. Surface water, such as rivers and reservoirs, generally differs in water composition compared to deep wells. When considering whole-home drinking water quality, it is important to recognize that surface water systems typically undergo multiple treatment processes to address naturally occurring constituents and potential contaminants before distribution.
2. Reading Median and Range Values from the Public Water Record
The recent EPA record for Flagstaff’s public water system includes a lead 90th percentile value, a measure related to lead levels in plumbing materials rather than source water. For example, the lead 90th percentile was recorded at 0.0036 mg/L in late 2023. This figure helps indicate typical lead levels found in household taps across the system but does not imply the same concentration in your home’s water unless individually tested.
3. Plumbing Material and Age Can Impact Water Quality Separately
Water quality at the tap can vary due to the materials and age of household plumbing independent of source water. Metals like lead or copper may leach from older pipes or fixtures under certain conditions, influencing what you experience in your home. Municipal water can meet regulatory standards at the system level while individual homes see different results based on their internal plumbing.
4. Which Fixtures and Appliances Show Quality Differences First?
Fixtures like kitchen taps used for drinking and cooking are often the first to reveal water quality issues related to plumbing since water may stagnate in pipes overnight. Appliances such as coffee makers and ice machines are also sensitive to water composition changes. Identifying these early helps determine if a whole-home approach to water treatment is necessary.
5. Understanding the Sample Size Behind the Public Water Report
The Flagstaff system serves nearly 80,000 people through over 23,000 connections. The water quality data is based on numerous samples across the system but focuses on system-wide averages rather than individual taps. A small number of samples in any localized area may not fully represent variation across all homes, underscoring the value of specific household testing to know your own water profile.
