What Austin homeowners should know
If you are buying or renting in Austin, start by confirming whether the property is served by Austin Water or another nearby provider. Then separate your concern into source water, report data, hardness, taste or odor, plumbing, lead, PFAS, private wells, or a specific address-level issue.
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 Austin, 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.
