Start with Martin County’s address-level resources
Use the Martin County utility service-area map, then confirm the provider on the current water bill. A Palm City mailing address does not prove supplier, and an irrigation well does not necessarily supply the home.
When Martin County Utilities supplies the home
The County publishes its 2025 Drinking Water Quality Report, identifying public water system 4431891. Use the report for customers of that system; it is not a result at an individual tap and does not describe another utility or a private well. No numerical hardness or contaminant result is assumed for your home.
When a private well supplies the home
Begin with property-specific testing. EPA’s private-well guidance connects staining with tests for iron, copper or manganese; odor can require a different investigation. A measured problem, available pump flow and maintenance needs determine treatment. A municipal compliance report cannot substitute for well sampling.
Choose the next conversation
For measured staining, read iron filtration. For odor, read sulfur and odor assessment. For scale, compare softening. Use well treatment for a combined plan or testing when the source or cause is unclear.
