This Arizona Daily Star photo, taken in 2005, shows the effects of a high ozone-level day on Tucson.

Wednesday October 10, 2018. 2:30 – 3:30 p.m., Arizona Senior Academy Great Room.

Ground-level ozone and particulate matter are two air quality issues in the news these days, and a spokesperson for the Pima County Department of Environmental Quality (PDEQ) will discuss these and other air pollution problems in a talk at the Arizona Senior Academy on October 10.

Karen Wilhelmsen, Community Education Manager for the PDEQ’s Clean Air Program, will discuss the sources of air pollution, the department’s monitoring network, how air pollution affects human health and the environment, accessing current and historical air quality data, and actions we can take to protect ourselves and help keep the air healthy to breathe.

Wilhelmsen coordinates youth and adult education programs regarding air quality and related environmental topics. She develops and provides presentations for schools, business and community groups to enhance classroom lessons or assist with compliance on air quality rules and regulations. She creates educational activities and displays for community events and helps plan public meetings and the annual Tucson Earth Day Festival.

She earned a Bachelor of Arts Degree in Fine Arts and a Bachelor of Arts in Interdisciplinary Studies incorporating Environmental Sciences, Marketing, and Fine Arts, both from the University of Arizona. After spending time traveling solo across the U.S. and seeing first-hand how the earth is being disregarded in our everyday living, Karen made her career choice at the age of 24. It soon became her mission to help protect the environment by spreading the word and getting others to take action, too.

PDEQ was developed in 1989 to provide monitoring for air quality, water quality, hazardous waste, and solid waste. The department processes environmental permits, assists in waste minimization and pollution prevention, and responds to public complaints with investigations and enforcement.
