Quick summary
Memphis is a distinctive water profile because the public drinking-water story is groundwater-focused rather than a surface-water reservoir system. MLGW's report points to the Memphis Sand Aquifer as the primary source, which makes the page useful even before a hardness number is added.
For Memphis, use the public report for system-level context and a home test for address-specific questions like scale, taste, staining, or older plumbing.
Provider context
Primary provider context: Memphis Light, Gas and Water.
Memphis Light, Gas and Water is the primary provider context for this profile. Users outside the city or near service boundaries should still confirm the provider serving the address.
Source-water context
MLGW's official report describes Memphis as being supplied by groundwater from the Memphis Sand Aquifer. That source context matters for taste, mineral questions, and how users interpret generic filter or softener advice.
Compare water hardness by city
Water hardness in Memphis
A clear source-backed Memphis hardness value from the reviewed public sources. Because groundwater systems can have meaningful mineral variation, use MLGW's current report, direct utility guidance, or a direct hardness test before sizing equipment.
For scale, spots, or appliance buildup, treat published hardness as a planning clue and test at the home before sizing equipment.
Water quality reports
Use the MLGW report for official system-level water-quality results and source context. It does not test a specific building's plumbing, fixtures, private treatment system, or faucet.
Should you test your water?
A local test is most useful when the question is about the property itself: plumbing age, taste, odor, staining, sediment, private-well context, or treatment-equipment sizing.
For Memphis, testing is most useful when the provider is uncertain, the building is older, or you are making a treatment-equipment decision based on hardness, scale, taste, or a specific contaminant concern.
