St Gerald Catholic School Monitoring Portable Monitor

The Customer

Saint Gerald Catholic School, located in Ralston, was founded in 1959. The school prides itself on providing a strong faith-filled environment and is an accredited school with high academic standards.

The Metropolitan Area Planning Agency (MAPA) is a regional Council of Governments. They bring local and regional officials together with citizens in Eastern Nebraska and Western Iowa to connect and plan with them. MAPA helps member governments to address regional problems that may cross jurisdictional boundaries, including air quality. MAPA provided Saint Gerald School with the use of Aeroqual’s Series 500 Ozone Monitors free of charge, as part of its Little Steps Big Impact ozone awareness and education campaign.

Aeroqual’s monitors provide students with real numbers so they have a visual tool which illustrates the presence of air pollution in the environment.

The Problem

In 2010 and 2011, the U.S. Environmental Protection Agency (EPA) began reviewing the recommended acceptable limit for ozone, considering lowering it to 70 PPB. This was a problem for the Omaha Metro region, as they could be at risk of going into non-attainment due to the area already hovering around 70 PPB for several years. Potential consequences could be stricter controls, economic consequences, and more state oversight by the U.S. EPA.

This sparked conversations between MAPA and other agencies and stakeholders about how they could raise awareness of the problem and encourage people in the area to help. In October 2015, the U.S. EPA was convinced on the negative health effects of ground-level ozone and the stricter standard of 70PPB came into effect.

Also wanting to create awareness of human impact on the environment was Saint Gerald teacher, Kendra Sullivan. Kendra’s problem was finding a way to teach air pollution to her fifth-graders that would engage and interest them.

The shared problem between Saint Gerald School and MAPA was how to provoke change and educate people that common daily activities, such as driving, play a huge part in contributing to ground-level ozone.


In 2011, MAPA launched Little Steps Big impact, a campaign created to educate and raise awareness that “you can make a difference” in reducing ground-level ozone. In 2016, MAPA created the school ozone monitoring program as an opportunity to educate students. Saint Gerald School was one of the first schools to participate in the program.

MAPA provided Saint Gerald’s, and other participating schools, with teaching material and Aeroqual’s Series 500 Ozone Monitors, purchased from Aeroqual channel partner, Ozone Solutions. The easy-to-use portable monitors gave students hands-on experience measuring ground-level ozone in real time. In small groups, students collected and recorded ozone levels at various times and locations, seeing first-hand the impact of human daily activities on ozone levels. They were able to take their classroom knowledge about air pollution and its impact and test it in the field.

Sue Cutsforth, MAPA’s Information Officer, says that the Saint Gerald School students “have been very engaged in this project and show a great zest for knowledge about air pollution, its causes, and how they can help improve air quality.”

Allowing students to monitor ground-level ozone was a great way for them to verify the issue for themselves and encouraged them to care. This approach is supported by several studies that show students learn best and retain more information when their learning is active.

The impact of the program was shown when a St. Gerald School student took her learnings home. The student informed her parents about the air pollution caused from idling vehicles and requested for the car to be turned off when waiting in the school pick-up zone.

In 2018, because of the success of the program with schools like Saint Gerald Catholic School, MAPA secured a grant of $55,000 from the Nebraska Environmental Trust so they can continue the program and expand it to more schools in the region.
