Steven Arnold has been involved in air quality work in Colorado for over 50 years, spanning a range of field work in air monitoring to developing elements of local air pollution plans, including managing projects related to air quality and other environmental planning work.


Steven earned his Bachelor’s degree in Chemistry from Western State Colorado University and a Master of Arts in Analytical and Inorganic Chemistry from San Diego State University with a focus on measuring boron pollution in sea water to examine pollution from the shipping industry.

Professional Background

Steven started his career as an analytical chemist for the State of Colorado’s Department of Public Health and Environment. He was involved in expanding and redeveloping the newly formed Air Pollution Control Division’s (APCD) air monitoring system in the Technical Services Program. Later he managed the Technical Services Program for ten years. At the APCD, as the Deputy Director of the Division, he was involved with the Western Regional Air Partnership (WRAP) in the development of the multi-state coordinated effort to develop statewide visibility plans to protect visual air quality in National Parks and Wilderness areas.

He was involved in the development of all of Colorado’s State Implementation Plans (SIPS), studies about Denver’s Brown Cloud and in the preparation of several greenhouse gas inventories. He currently is retired from the State. He currently serves on the Regional Air Quality Council’s Board as a citizen representative, aiding in a process to develop ozone control plans for the Denver metropolitan non-attainment areas.

Motivation for Teaching

Steven believes helping students build a foundation to understand underlying cause-and-effect relationships of environmental problems helps future generations see how they can improve the environment through personal and corporate actions. Both individual and collaborative problem-solving skills are exercised in his courses to examine environmental problems and offer solutions with the goal of building living habits for a more sustainable environmental outcome.

Helping Students Be Successful

Steven uses current air quality planning processes as the backdrop for understanding a broader range of environmental issues. He is available through the Canvas email system.
