Biohazard and Pathogen Disinfection in Johnson, AR

Johnson is a city in Washington County, Arkansas — a place, not a person or a county — located in the Ozark Mountains between Fayetteville and Springdale in the Northwest Arkansas metropolitan area.

Johnson's known history begins in 1830–1834, when John Trusdale purchased a mill site west of present-day Johnson and in 1835 built a gristmill powered by the flow of natural springs.

Early settlers built an economy on the community's natural springs and valleys, including lime mining, the Johnson Mill, and trout.

A post office opened in the community in 1887, but Johnson did not incorporate until March 6, 1961, when local leaders needed a city government to obtain water and sewer services.

Johnson long remained tiny — it had only 274 residents in 1970 and 599 in 1990 — before booming to 2,319 people in 2000 and 3,609 in the 2020 census.

The 2020 census counted 1,487 households and 902 families in Johnson.

Johnson functions largely as a bedroom community, and much of its growth came from apartment complexes occupied by students of the University of Arkansas in nearby Fayetteville.

Because Springdale annexed land to Johnson's north and Fayetteville annexed land to its south in the 1990s, Johnson was forced to draw its growing boundaries toward the west.

The historic Johnson Mill, powered by the area's springs, remains the city's emblematic landmark.

The nearly three-mile Clear Creek Trail runs through Johnson, connecting to Lake Fayetteville Park and the 40-mile Northwest Arkansas Razorback Regional Greenway between Fayetteville and Bentonville.
