Homewood Water Hardness & Quality Report (2026)

Birmingham Water Works (BWW) serves Homewood, Alabama, in Jefferson County, providing water to approximately 585,000 people across central Alabama including Birmingham, Homewood, Hoover, and surrounding communities. The primary source is surface water from the Cahaba River and Lake Purdy Reservoir, supplemented by groundwater from the Valley-Head Aquifer. Treatment occurs at the William E. Swann and J.H. Carter plants, employing coagulation, sedimentation, filtration, and chlorination to meet EPA standards. Annual Consumer Confidence Reports confirm compliance, with pH maintained around 7.5–8.5 for corrosion control.

The Cahaba River Watershed spans the Cahaba Valley, underlain by Paleozoic sedimentary rocks including the Bangor Limestone (Mississippian) and Pottsville Formation sandstones (Pennsylvanian), which weather to release dissolved minerals into surface runoff and shallow groundwater. The Valley-Head Aquifer taps shallow alluvial and fractured bedrock layers in the Appalachian Plateau transition zone. Natural dissolution of carbonates imparts a moderately mineralised character, producing a moderately hard supply prone to scale formation without excessive mineral concentration.

Moderately hard water in Homewood leads to moderate scale buildup in water heaters, dishwashers, and washing machines, reducing efficiency and increasing energy costs by 20–30% over time. Faucet aerators and showerheads may clog, causing reduced flow and drier skin and hair. Monthly vinegar descaling, annual appliance flushes, and a water softener are recommended, especially in older homes with galvanized pipes. The 2025 CCR notes 2 contaminants exceeding health-based MCLGs; no MCL violations are reported, and PFAS levels are low — filtration is advised for sensitive groups per tapwaterdata.com.
