Is My Florida Water Safe? Tap Water Quality by County

Is My Florida Water Safe?

Tap water quality by county — contaminants, CCR guide & filter recommendations for FL homeowners.

Florida Public Water Overview

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 does not equal zero risk.

What is a CCR?

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).

"At or below the MCL" does not mean Safe — it means Legal. 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.

How to Find Your CCR

Search the EPA ECHO database at echo.epa.gov for your water system's CCR. Or visit the FL DEP CCR portal. You can also call your utility's customer service directly.

What to Look For in Your CCR

• Are TTHMs detected? Compare vs. MCL (80 ppb). If >50 ppb, investigate. FL surface water systems routinely approach this.
• Are HAAs (Haloacetic Acids) detected? Compare vs. MCL (60 ppb). HAAs persist in cold water — refrigerator filtration matters.
• Is lead detected? Any non-zero level warrants a faucet filter if you have children. MCLG = 0; no safe level for children.
• Is arsenic detected? >5 ppb in groundwater systems is worth filtering. MCL 10 ppb, MCLG 0. Common in Floridan Aquifer systems.
• Is nitrate detected? >7 mg/L is concerning with infants. MCL 10 mg/L — at that level, infant formula is a real risk.
• Are PFAS listed? Most pre-2024 CCRs won't list them. Absence in CCR does not mean absent in water. EPA MCL effective 2024.
• What's the water source? Surface water = higher DBPs. Groundwater = higher minerals/arsenic.

What Actually Removes What — FL Buyer's Guide

Pitcher Filters (Brita, PUR, ZeroWater) — $20–$50: Good for chlorine taste/odor, some lead (NSF 53 models only). NOT effective for PFAS, nitrates, bacteria, arsenic. FL note: ZeroWater removes high TDS but may taste flat/slightly acidic. Replace every 40 gallons (faster in FL's high-TDS water).

Under-Sink Reverse Osmosis (RO) — $300–$1,200 installed (Recommended for FL): Removes PFAS, lead, arsenic, nitrates, DBPs, TDS, hardness. NSF/ANSI 58 certified systems are the gold standard — the only NSF-certified tech that reliably removes PFAS below detection. FL consideration: RO wastes water (~3:1 ratio); consider high-efficiency RO. RO water is slightly acidic and soft; many add a remineralization stage. Filter replacement $100–$200/year.

Whole-Home Carbon Filtration — $400–$2,000 installed: Removes chlorine, some DBPs, VOCs, odors. Does NOT remove PFAS, nitrates, arsenic, or heavy metals. Best as a first stage with under-sink RO.

Water Softener — $800–$3,000: Removes hardness (calcium/magnesium), extends appliance life. Does NOT remove contaminants — it swaps calcium for sodium. FL regulation note: counties vary on salt-discharge rules — check before purchasing. Salt-free TAC (Template Assisted Crystallization) systems are an alternative.

UV Sterilizer (For Well Water) — $300–$900 installed: Kills bacteria and viruses but does NOT remove chemical contaminants. Install after sediment and carbon pre-filtration.

What NOT to Buy in FL

• Magnetic water conditioners / "electronic descalers": No scientific evidence of effectiveness for hard water. Frequently sold door-to-door in FL. 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.
