Well Water Treatment in Coral Gables

City water is the norm in the Gables

The Miami-Dade Water and Sewer Department (WASD) supplies drinking water in Coral Gables from Biscayne Aquifer wells that average about 80 feet deep, treated mostly at the Alexander Orr, Jr. plant. If your home is connected to WASD, you are not on a private drinking well even if you also have a well for the lawn.

Irrigation wells

Irrigation wells tap the same shallow aquifer for lawn and garden watering. They are not meant for drinking. The usual complaints are orange iron stains and sulfur smell from sprinklers. Miami-Dade's year-round watering restrictions apply to private wells as well as city water: two days a week by address, and not between 10 a.m. and 4 p.m., as the City of Coral Gables notes.

Private drinking wells: what DOH recommends

If any part of your property relies on a private well for household water, the Florida Department of Health recommends:

• Testing for bacteria and nitrate at least once per year
• Testing for coliform bacteria, nitrate and lead when buying or selling a home with a well
• Contacting your county health department for sampling instructions

DOH also notes that local land use may call for additional tests. About half of Coral Gables properties are on septic systems, according to the city, which is one more reason to keep well water tested and the well properly located and maintained.

Common well-water conditions

• Iron: orange staining, metallic taste
• Hydrogen sulfide: rotten-egg smell
• Hardness: scale, from the limestone aquifer
• Bacteria: only a lab test can confirm; disinfection options such as UV may be considered

Compare UV disinfection vs. reverse osmosis for wells.

How a well system is configured

Living Water's well water treatment is built from your well's test results. That can mean oxidation and filtration for iron and sulfur, softening for hardness, and a drinking-water stage where needed. Any system meant to address bacteria or a specific contaminant should be certified for that purpose; check the model's listing.
