Siloam Springs is a city in Benton County, Arkansas, United States. 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. The town 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. John Brown University (JBU) was founded in 1919 as a private, interdenominational, Christian liberal arts college in the city. Today, Siloam Springs is known for its efforts to preserve and revitalize the city's historic downtown and as a promoter of the arts via Sager Creek Arts Center and the JBU art gallery. The community is located on the western edge of the growing Northwest Arkansas metropolitan area and has had a population increase of 47% to 15,039 between the 2000 and 2010 censuses.

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

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.

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. 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. 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). 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.
