Free Water Testing in Miami: What an in-home test measures
Miami (population about 439,000 residents, in Miami-Dade County) is served by Miami-Dade Water and Sewer Department (WASD). Source water: Biscayne Aquifer groundwater, with approximately 330 million gallons per day withdrawn from shallow wells averaging 80 feet deep, supplemented by Floridan Aquifer water treated at the Alexander Orr plant. On-site testing of Miami finished water typically reads 7 to 11 grains per gallon for hardness.
Why a free in-home test makes sense here in Miami
Miami drinks Biscayne Aquifer water finished by Miami-Dade WASD, where the 2024 Annual Water Quality Report documents PFOA at 16 ppt and PFOS at 31 ppt, both above the EPA 2024 final MCL of 4 ppt.
For Miami homeowners that translates into a specific set of treatment priorities. We commonly hear about:
- Hardness scaling on glass shower doors and water heaters
- Chlorine taste in cold drinking and ice water
- Reddish or yellow staining on fixtures (iron)
- Cloudy water at first draw (dissolved gas or sediment)
- Soap that will not lather (high hardness)
What is in Miami water (notable details)
- free chlorine secondary disinfection with TTHM and HAA5 reported in WASD's annual Consumer Confidence Report; the Biscayne Aquifer is a shallow groundwater system and the WASD CCR is the canonical record for finished-water quality (source)
- Biscayne Aquifer wellfields are surrounded by urbanization and the Florida Department of Environmental Protection and Miami-Dade DERM actively manage source water protection zones to limit industrial, agricultural, and stormwater impacts (source)
