MEMPHIS LIGHT, GAS, & WATER
This is the federal compliance record — what EPA has cited this utility for. It is not a water quality test. A system with no violations has not been shown to be clean; it has nothing reported, which is a weaker claim than it looks. The actual measured contaminant levels are in the utility’s annual Consumer Confidence Report, which every US utility must publish and which is not in this dataset.

Every citation on this system is a monitoring or reporting failure rather than a health-based one — paperwork, not contamination. That is worth knowing before spending anything: it is not evidence you need a filter. Test your own tap for $14 and decide on the number, not on the utility's admin record.
Test before you spendA federal record describes a utility. It cannot describe the pipe between the main and your kitchen, which is where lead usually comes from. Your own tap is the only thing that answers your own question.

Tells you your dissolved-solids number in about four seconds, which is where every decision on this site should start.
TDS is not a safety measurement. It counts dissolved solids and cannot see lead, PFAS or bacteria. It tells you how hard your water is and whether a filter is still doing anything — nothing more. Anyone selling you a system on a TDS reading alone is misleading you.

The one that has been in service vans for fifteen years. Holds calibration better than the cheap ones.
Same limitation as every TDS meter, and it looks like it was designed in 2009 because it was.
