Eniwa's air quality reflects the Hokkaido central Chitose River plain position adjacent to New Chitose Airport and the JGSDF Eniwa training area, with vehicle traffic on surrounding roads and the military operations and residential character contributing local sources. The clean Hokkaido boreal setting generally maintains moderate conditions, while the aviation background from the nearby airport and wood-burning stoves during extreme Hokkaido winters add seasonal contributions throughout most of the year.
