Home Water Testing in Miami

Why test at the tap if WASD already tests?

WASD monitors its water constantly and publishes the results every year. That report describes the water leaving the plants and moving through the county system. It cannot describe the last stretch: your building's pipes, your water heater, an old filter someone left behind, or how your own fixtures behave.

Miami also has more than one supply path. WASD's report says homes north of SW 8 Street are generally supplied by the Hialeah and John E. Preston plants, and homes south of it by the Alexander Orr, Jr. plant. A test at your tap shows what you are actually getting.

What happens during the free visit

1. Jorge asks what you notice: smell, taste, spots, scale, or something specific.
2. He tests water from your tap and walks you through each result as it comes up.
3. He explains what the results mean for your home in plain words.
4. If a system would help, he recommends the one that fits. If not, he says so.

How to read Miami-Dade's Water Quality Report

WASD's annual Water Quality Report (its Consumer Confidence Report) is posted on miamidade.gov. A few tips:

• Find the Main System columns; that is the system serving the City of Miami.
• Look for chloramines in the disinfectants section. That is the disinfectant that causes the familiar taste and smell.
• Compare each result with its MCL (the legal limit). The report notes whether there were violations.
• For questions, the report lists WASD water quality lines: 786-552-4738 for the Hialeah and Preston plants and 786-552-4181 for the Orr plant.

WASD also keeps an inventory of service line materials at miamidade.gov/knowyourpipes.

Home screening vs. certified lab analysis

An in-home screening is fast and practical for the things that drive most filtration decisions, like hardness and disinfectant taste. If you need a documented result for a specific contaminant, such as lead from home plumbing, a state-certified laboratory is the right tool. Jorge can tell you when a lab test makes sense. Compare the two in home screening vs. lab analysis.

Good times to test in Miami

• You just moved into a house or condo and do not know what was installed before.
• You notice a stronger chlorine smell, which can happen when WASD temporarily switches disinfectants during system maintenance.
• You see scale or spots and want to know if a softener is worth it.
• You are on a private well, where there is no utility testing at all.
• You are comparing quotes and want a neutral starting point.
