About Air Quality in Wooldridge
The US Air Quality Index (AQI) is a standardized scale from 0 to 500 used by the EPA to communicate how clean or polluted the air is. Values of 0–50 are considered Good, 51–100 Moderate, 101–150 Unhealthy for Sensitive Groups, 151–200 Unhealthy, and above 200 Very Unhealthy or Hazardous.
PM2.5 (fine particulate matter under 2.5 micrometers) is the most closely monitored pollutant for health impacts. Long-term exposure to elevated PM2.5 is linked to heart disease, lung cancer, and respiratory illness. PM10 includes larger particles from dust, pollen, and mold.

Frequently Asked Questions
What is a good AQI level?▾
An AQI of 0–50 is considered Good — air quality is satisfactory and poses little or no health risk. An AQI of 51–100 is Moderate — acceptable, though sensitive individuals may experience minor effects. For most healthy adults, AQI below 100 is fine for outdoor activities. Above 150, everyone may start to experience health effects.
What causes bad air quality?▾
Common causes of poor air quality include: vehicle exhaust and industrial emissions (nitrogen dioxide, ozone), wildfires (smoke containing PM2.5), construction and agriculture (dust, PM10), and temperature inversions that trap pollutants near the ground. Weather patterns, wind, and topography all affect how pollutants disperse.
What is PM2.5 and why does it matter?▾
PM2.5 refers to fine particulate matter — particles smaller than 2.5 micrometers in diameter. They're small enough to penetrate deep into the lungs and enter the bloodstream. Short-term exposure can cause respiratory irritation; long-term exposure is linked to cardiovascular disease, lung cancer, and premature death. WHO recommends annual average PM2.5 below 5 µg/m³.
