Siloam Springs is a city in Benton County, Arkansas, United States, and located on the western edge of the Northwest Arkansas metropolitan area. As of the 2020 census, the population of the city was 17,287. The community was founded in 1882 and was characterized by the purported healing powers of the spring water feeding Sager Creek and trading with nearby Native American tribes. The city shares a border on the Arkansas–Oklahoma state line with the city of West Siloam Springs, Oklahoma, which is within the Cherokee Nation territory. It is home of John Brown University.


The historic downtown of Siloam Springs was first founded as a resort town surrounding the healing waters of the springs

Osage Indians were the known first inhabitants of the area. Siloam Springs' first white settlers were of German and Scots-Irish origin. Simon Sager is considered the founder of the town, then known as Hico.[3]

In 2012, the city was named one of the 20 best small towns in America by Smithsonian magazine[4]


Sager Creek

The area is located in the Mid-South region of the country where the southern plains meet the Ozark Mountains. The city sits atop a plateau with many dogwood trees growing across the landscape.

A perennial creek, named after the founder, Sager Creek, flows through the downtown area.

According to the United States Census Bureau, the city has a total area of 11.2 square miles (28.9 km2), of which 11.1 square miles (28.7 km2) is land and 0.077 square miles (0.2 km2), or 0.71%, is water.[5]

Siloam Springs is at the extreme western edge of this area, connected to the principal cities by Highway 412.

Temperatures above 100 °F (37.8 °C) are rare but not uncommon, occurring on average twice a year. January is the coldest month with an average high of 44.3 °F (6.8 °C) and an average low of 24.2 °F (−4.3 °C). Highs below 32 °F (0.0 °C) occur on average thirteen times a year, with 2.2 nights per year dropping below 0 °F (−17.8 °C).

The spring wet season is more pronounced than fall, with the highest rainfall in May. This differs slightly from the climate in central Arkansas, where the fall wet season is more comparable to spring.

Primary clarifier (foreground) and aeration basins (background) at Siloam Springs Wastewater Treatment Plant

The city's primary water source is the Illinois River, although some water is purchased from Benton - Washington Regional Public Water Authority, whose source is Beaver Lake.[15] The water is treated with chlorine, and the by-products of this chlorination process are kept compliant with the Arkansas Department of Health standards. Fluoride is added to supplement the naturally occurring amount present prior to treatment.

Wastewater is treated at the Siloam Springs Wastewater Treatment Plant (SSWWTP). Since effluent is discharged into a tributary of the Illinois, the plant's effluent is required to meet the treatment standards of both Arkansas and Oklahoma. The phosphorus load of the Illinois has been subject of controversy in the area, even reaching the United States Supreme Court in 1992. The Environmental Protection Agency (EPA) has classified the Illinois as Section 303(d) of the Clean Water Act, listing it as an "impaired and threatened water" due to the high phosphorus loads.[16] As a result of the applicable strict phosphorus effluent regulations, SSWWTP upgraded its system in 2011. The upgrades also increased capacity 25% to 5.5 million gallons per day (MGD) (14,474 liters per hour).[17] Although presently a traditional biological nutrient removal (BNR) plant capable of meeting the interim phosphorus limit, pilot tests have proven a chemical nutrient removal (CNR) and membrane biological reactor combination to be effective well below the possible future permit limit. However, due to the high cost, these phases have been delayed. Currently, a 3-year study is being conducted to determine the background phosphorus level in the Illinois. The future effluent limits will likely be written following the conclusion of the study. An EPA total maximum daily load (TMDL) study in the watershed is also ongoing.[18]
