Tap water quality by county — contaminants, CCR guide & filter recommendations for FL homeowners
All FL public water systems must meet EPA/FDEP Safe Drinking Water Act standards and publish annual CCR reports. Florida has 3,847 community water systems serving ~20 million people. Compliance ≠ zero risk — read on for what your area's water typically contains.

Every FL public water system serving 25+ people must publish an annual Consumer Confidence Report (CCR) by July 1. The CCR lists all detected contaminants, the MCL (Maximum Contaminant Level — the legal limit), and the MCLG (the level with no known health risk — often lower than the MCL, or zero for carcinogens).
The MCLG is the health-protective target. For known carcinogens like TTHMs and HAAs, the MCLG is zero — but the enforceable MCL is higher. If your CCR says "detected TTHMs: 65 ppb, MCL: 80 ppb" — you're technically compliant but in the top 20% of FL for DBP exposure.
Always compare: detected level vs. MCL vs. MCLG. The gap between MCLG and MCL is where risk lives.
Search the EPA ECHO database at echo.epa.gov for your water system's CCR. Or visit FL DEP CCR portal. You can also call your utility's customer service directly.

❌ NOT effective for: PFAS, nitrates, bacteria, arsenic
🇫🇱 FL-specific note: ZeroWater is popular in FL because it removes the high TDS (hardness minerals) giving zero-TDS water. However, zero-TDS water may taste flat and can be slightly acidic — not ideal for long-term use without remineralization. Replace every 40 gallons (more often in FL's high-TDS water — you'll go through cartridges fast).
NSF/ANSI 58 certified systems are the gold standard. RO is the only NSF-certified technology that reliably removes PFAS to below detection limits.
🇫🇱 FL consideration: RO wastes water (typically 3:1 waste-to-product ratio). In FL's drought-prone areas, consider high-efficiency RO (1:1 or 2:1 ratio). RO water is slightly acidic and soft — many FL homeowners add a remineralization stage. Filter replacement: $100–$200/year.
✅ Removes: Chlorine, some DBPs, VOCs, odors — best for chlorine taste/smell throughout the house.
❌ Does NOT remove: PFAS, nitrates, arsenic, or heavy metals.
Best as a first stage in a whole-home + under-sink RO setup for comprehensive FL protection.
✅ Removes hardness (calcium/magnesium). Significantly extends appliance life, reduces scale on fixtures and water heaters.
❌ Does NOT remove contaminants — it replaces calcium ions with sodium ions. If you have PFAS or lead concerns, you still need a separate RO or NSF 53 filter.
⚠️ FL regulation note: FL counties vary on salt-discharge rules for softeners — check with your county before purchasing. Salt-free TAC (Template Assisted Crystallization) systems are available as an alternative.
UV kills bacteria and viruses but does NOT remove chemical contaminants. Always install after sediment and carbon pre-filtration — particles block UV effectiveness and allow pathogens to hide.
Magnetic water conditioners / "electronic descalers": No scientific evidence of effectiveness for hard water. Frequently sold door-to-door in FL by high-pressure sales teams. Save your money.
Alkaline water machines ($2,000–$5,000): Zero peer-reviewed evidence of health benefits. Not a filtration device. FL tap water already has high pH due to limestone.
Tip: FL DOH county environmental health offices can refer you to accredited labs. Search floridahealth.gov for your county office.
