Bartlett Water Hardness & Quality Report (2026)

The Bartlett Water System, operated by the City of Bartlett, Tennessee, serves approximately 59,017 residents in Bartlett and parts of Shelby County. The utility draws its entire supply from groundwater wells tapping the Memphis Sands aquifer. Water is treated at facilities managed by the Water Treatment Division, located at 6400 Stage Road, Bartlett, TN 38134, with daily monitoring to meet or exceed federal and state standards; testing is conducted annually or every three to five years as required.

The supply originates within the Mississippi Embayment watershed, where the Memphis Sands aquifer provides a confined groundwater resource underlain and overlain by clays that limit surface influences. The aquifer consists of unconsolidated, quartz-rich sands and gravels of Tertiary age from the Claiborne Group, deposited in ancient Eocene coastal plain environments. The absence of significant carbonate formations such as limestone or dolomite in the primary flow paths results in naturally low dissolved solids and a soft supply character shaped by brief water-rock interactions in the sandy matrix.

As a soft supply, Bartlett's water poses minimal scaling risks to household systems, with little buildup on fixtures, pipes, or heating elements. Appliances like water heaters and dishwashers experience extended lifespans without frequent descaling; soap and detergents lather easily, reducing usage. No softener is typically recommended — focus maintenance on standard filtration if concerned about disinfection byproducts. Independent assessments note Total Trihalomethanes (TTHMs) and haloacetic acids exceeding health guidelines; chlorine residuals average 0.9–1.3 ppm; fluoride is added; and PFAS are flagged as risks in susceptibility ratings.
