Bartlett Water Hardness & Quality Report (2026)

Bartlett, Tennessee, in northeast Shelby County — one of the fastest-growing Memphis suburbs in the 2000s–2010s, a prosperous northeast Shelby County residential community adjacent to Germantown — draws its municipal water supply from the Memphis Sand Aquifer (Memphis Sands, Eocene Claiborne Group — Memphis Sand Formation and Cockfield Formation) via the Memphis Light Gas and Water (MLGW) utility, with some supply through the City of Bartlett Public Works Water Division. Water hardness in Bartlett measures 173.5 mg/L — classified as hard.

Bartlett's hard supply reflects the Memphis Sand Aquifer's calcareous characteristics in the northeast Shelby County zone. The Memphis Sand Formation (the primary Memphis metropolitan drinking water aquifer, an Eocene formation of calcareous quartz sand with calcareous cement) is one of the largest and most productive sandstone aquifers in the central United States. In northeast Shelby County at Bartlett, the Memphis Sand carries moderate dissolved calcium from the calcareous Eocene sand cement and from the overlying calcareous alluvial recharge zones of the Mississippi River floodplain. The northeast Bartlett zone of the Memphis metropolitan water system receives Memphis Sand water of slightly higher mineral content than some inner Memphis zones, producing the 173.5 mg/L.

At 173.5 mg/L, Bartlett residents face regular hard water challenges. Scale deposits form on faucet aerators, showerheads, and appliances within weeks — monthly descaling with citric acid solution is standard maintenance. MLGW and City of Bartlett consistently deliver water meeting all Tennessee TDEC and EPA Safe Drinking Water Act requirements.
