Olive Branch Water Hardness & Quality Report (2026)

Olive Branch, Mississippi, in DeSoto County — one of the fastest-growing cities in Mississippi (Olive Branch has been consistently among the fastest-growing cities in the entire southeastern US — a major DeSoto County suburban community in the Memphis, Tennessee metropolitan area directly across the state line), a rapidly growing DeSoto County community with a large distribution and logistics corridor (the Olive Branch–DeSoto County I-269 logistics and warehouse corridor is one of the largest in the mid-South), a diverse DeSoto County community with a significant African-American and Hispanic-American population, and a major suburb in the Memphis metropolitan area — draws its municipal water supply from the Memphis Sand Aquifer via the City of Olive Branch Water Division. Water hardness in Olive Branch measures 159 mg/L — classified as moderately hard.

Olive Branch's moderate hardness reflects the DeSoto County Memphis Sand Aquifer (Middle Claiborne Aquifer) geology. The Memphis Sand Aquifer at Olive Branch–DeSoto County draws from the Eocene Memphis Sand of the Middle Claiborne Group (calcareous-moderate well-sorted sand — the primary aquifer of the Memphis metropolitan area, an exceptionally thick and productive aquifer covering northern Mississippi, western Tennessee, and adjacent states). The City of Olive Branch treatment produces the moderate 159 mg/L.

At 159 mg/L, Olive Branch residents encounter moderate-to-hard scale accumulation. Monthly cleaning with citric acid solution is recommended. City of Olive Branch Water Division consistently delivers water meeting all Mississippi DEQ and EPA Safe Drinking Water Act requirements.
