The air monitoring station at Hillcrest High School helps the Missouri Department of Natural Resources determine exposure to air pollutants of a segment of the Springfield population. Specifically, it meets the federal requirement to monitor exposure to ozone of a population of the Springfield metropolitan statistical area (MSA). The Hillcrest High School station began monitoring PM10 and PM2.5 concentrations, too, in April 2015 when the department relocated monitors at the Missouri State University (MSU) station to Hillcrest High School because of construction at the MSU site.
Pollutants
Ozone Pollutant
The primary National Ambient Air Quality Standard for ozone is 0.070 parts per million averaged over eight hours (annual fourth-highest daily maximum 8-hour concentration, averaged over three years). The federal ozone season for monitoring runs from March 1 to Oct. 31.
