About these numbers

Day counts come from the EPA's county air quality summaries, which take the worst reading across a county's monitors each day. Monitors here reported on about 365 days a year from 2021 to 2025. A county is large, and your street can be cleaner or worse. CDC's model, which estimates every county from monitors and satellites, gives the worst spot in El Paso County almost no high-particle days and about 10 high-ozone days a year from 2018 to 2022. That's well below what the monitors here recorded. The monitors are a direct measurement, so they're the number to trust.
