Scope and Sample Size Behind Arapahoe's Lead Data

The latest publicly available data from the EPA covers the Aurora City of public water system, which serves over half a million residents across more than 91,000 connections in Arapahoe County, Colorado. This dataset, compiled from samples taken as recently as December 2025, reflects lead levels measured at various points within the water distribution network, including plumbing. However, it represents aggregated results rather than details from any single household.

The lead level cited — the 90th percentile at 0.0025 mg/L — means that 90% of tested water samples have lead concentrations at or below this value. It does not reveal the lead concentration specific to any individual home or tap.

Public Water Records versus Private Well Testing

It's important to differentiate between public system data and private well water tests. Public water system figures are subject to routine monitoring and regulated treatment processes, ensuring consistent quality across the service area. In contrast, private well water quality varies widely based on local geology, well condition, and plumbing.

For residents on the Aurora City public water system in Arapahoe County, these results provide a general baseline but cannot replace direct testing of your household water to determine if lead levels inside your home differ due to your plumbing materials or fixtures.

Comparing Arapahoe's Record with Nearby Counties

While Arapahoe County's public water data shows no lead-related health-based violations, neighboring counties may have different water sources and treatment strategies, resulting in varied lead sampling outcomes. Thus, comparing Arapahoe's figures with adjacent jurisdictions offers some perspective but should not be overinterpreted to predict conditions in your household.

Each county’s water system operates independently, subject to different environmental factors and infrastructure.

Variations Over Time: Seasonal and Multi-Year Changes

The data reflects a snapshot at the end of 2025, but lead levels can fluctuate due to seasonal impacts on source water quality and maintenance activities within the distribution system. Because the EPA requires periodic sampling, multi-year trends can show stability or changes in lead presence. Arapahoe's current data shows no exceedances of health limits across prior assessments, indicating consistent management.

What Happens at the Tap with a Lead-Targeted Filter

Even with low lead detections in the system, households concerned about lead leaching from internal pipes may choose to treat water at the tap. The Fleck Lead in Water Filter ships ready to configure for residential use and is designed to reduce lead concentrations that test reports cannot specify for individual homes.

This technology works by targeting lead particles and dissolved lead forms that might enter household water after treatment, providing an added layer of protection tailored to your specific plumbing situation.

Next Steps: Testing Your Household Water for Lead

The single most definitive action is to have your own household water tested by a certified laboratory. Such testing will measure lead concentrations as they exist at your tap, reflecting your unique plumbing conditions.

If results show lead levels that concern you, considering a point-of-use treatment like the Fleck Lead in Water Filter can reduce your exposure. Otherwise, your home's lead risk remains aligned with the favorable data reported for Arapahoe’s public water system.
