Wind conditions pushed smoke from fires in several western states and Canada into South Dakota over the Labor Day weekend, adversely affecting air quality in the state.
According to a release from the South Dakota Department of Environment and Natural Resources, air quality monitoring sites in Rapid City, Wind Cave and the Badlands showed the 24-hour air quality standard of 35 micrograms per cubic meter was exceeded several times from Friday to Sunday.
The highest reading was 71.4 micrograms per cubic meter on Sunday at Wind Cave. Strong winds on Monday moved the heavy smoke conditions out of the state.
The DENR recommends visiting South Dakota’s Real Time Air Quality Index map at denr.sd.gov/des/aq/aarealtime.aspx to check if smoke is currently impacting the area.
