The South Dakota Department of Agriculture and Natural Resources (DANR) and the Department of Health (DOH) have issued an air quality alert for the state. The alert will be in effect from Saturday, May 31, 2025, through Sunday, June 1, 2025, or until conditions improve.
The smoke from wildfires poses a significant risk to certain groups. "Elderly citizens, young children, and individuals with respiratory problems are the most susceptible to the smoke," according to health officials. All residents are advised to limit physical exertion and minimize outdoor activities during periods of low visibility caused by wildfire smoke. Additionally, people should keep indoor air clean by closing windows and doors.
Air pollution can worsen heart and cardiovascular diseases as well as lung conditions like asthma and COPD. When air quality is poor, those with these conditions may experience symptoms such as chest pain, shortness of breath, wheezing, coughing, or fatigue. Anyone concerned about health effects related to poor air quality should contact their healthcare provider.
DANR provides air quality data on its website for several locations in South Dakota. Hourly PM2.5 values greater than 35 micrograms per cubic meter (ug/m3) are considered a public health concern.
Individuals can track real-time PM2.5 concentrations by visiting DANR’s website at https://denravweb.sd.gov/AirVision/default.aspx or the EPA’s website at https://www.airnow.gov/.
An explanation of the air quality index levels and their meaning is available at https://danr.sd.gov/Environment/AirQuality/AirMonitoring/RealTimeData.aspx.
