Your water supply was tested against federal EPA guidelines and health-based standards set by the EWG. We found 8 contaminants that exceed recommended health limits, including disinfection byproducts, heavy metals, and forever chemicals (PFAS). While the water meets legal minimum requirements, these levels may pose long-term health risks without additional in-home filtration.

Common Questions
Miami Water Quality FAQ
Miami-Dade County water meets all EPA and state regulatory standards, so it is legally considered safe. However, "safe" by federal standards does not mean contaminant-free. The Environmental Working Group (EWG) has identified multiple contaminants in Miami-Dade water that exceed their health guidelines, which are often stricter than federal legal limits. Many residents choose additional treatment for improved taste, reduced chemical exposure, and better protection for their families.
Miami-Dade's water comes from the Biscayne Aquifer, which sits in a limestone bedrock formation. As water passes through this rock, it dissolves calcium and magnesium minerals, creating very hard water. Typical hardness levels in Miami range from 15-25 grains per gallon, which is classified as "very hard." This causes white scale deposits on fixtures, reduces soap efficiency, and can shorten the lifespan of water heaters and appliances by years.
PFAS (per- and polyfluoroalkyl substances) are a class of over 9,000 synthetic chemicals known as "forever chemicals" because they do not break down naturally. They have been detected in Miami-Dade's water supply above the EPA's health advisory levels. The EPA issued new PFAS drinking water standards in 2024, setting legally enforceable limits for the first time. Reverse osmosis is one of the most effective methods for reducing PFAS in drinking water, achieving reduction rates of 90-97%.
A CrystalFlow water professional visits your home at a scheduled time convenient for you. The test takes approximately 20 minutes. We collect samples from your primary water source and test on-site for hardness, TDS, chlorine, pH, and other key parameters. For advanced testing (PFAS, heavy metals), samples are sent to a certified lab. You receive a detailed report with your results and a personalized recommendation. There is absolutely no obligation or cost.
