EPA records for MIAMI BEACH, CITY OF • Updated September 2026
Grade D — based on EPA compliance records, lead testing and PFAS monitoring
MIAMI BEACH, CITY OF has notable problems in EPA's records — health-based violations, elevated lead or PFAS above the federal limit. A certified filter is a reasonable precaution.
Miami Beach, FL tap water is legal to drink but grades D on EPA's records, mainly because of PFOA or PFOS measured at or above the 4 ppt federal limit in 2023–2025 EPA sampling and lead at 7 ppb (90th percentile) — under the 15 ppb action level but above 5 ppb. A certified filter matched to those findings is a reasonable precaution.
Miami Beach, FL tap water is legal to drink but grades D on EPA's records, mainly because of PFOA or PFOS measured at or above the 4 ppt federal limit in 2023–2025 EPA sampling and lead at 7 ppb (90th percentile) — under the 15 ppb action level but above 5 ppb. A certified filter matched to those findings is a reasonable precaution.
MIAMI BEACH, CITY OF's most recent Lead and Copper Rule result (2025-01-01 to 2025-12-01) was 7 ppb at the 90th percentile, below EPA's 15 ppb action level. Because lead usually comes from service lines and household plumbing, homes built before 1986 should still test at the tap.
Yes. EPA's UCMR5 sampling (2023-07-17 to 2024-02-05) detected 6:2 FTS, 8:2 FTS, PFBA, PFBS, PFHpA, PFHxA, PFHxS, PFOA, PFOS, PFPeA, with PFOA or PFOS at or above the 4 ppt federal MCL. Reverse osmosis and certified activated-carbon filters reduce PFAS.
MIAMI BEACH, CITY OF has 16 violations on file since 2016: 0 health-based in the last five years and 14 monitoring or reporting violations in that window. Monitoring violations are paperwork lapses, not measured contamination.
MIAMI BEACH, CITY OF reports purchased groundwater as its primary source and serves about 100,000 people (EPA PWSID FL4130901).
We recommend one. Reverse osmosis or a PFAS-certified carbon filter addresses the PFAS result. An NSF/ANSI 53 lead-certified filter addresses lead.

EPA Lead and Copper Rule 90th-percentile results reported by MIAMI BEACH, CITY OF
Below the action level, but detectable. In the most recent monitoring period on file (2025-01-01 to 2025-12-01), 90% of the homes MIAMI BEACH, CITY OF sampled had lead at or below 7 ppb.
EPA's action level is 15 ppb (dropping to 10 ppb under the 2024 Lead and Copper Rule Improvements). There is no safe level of lead; the 90th-percentile figure describes the system, not your tap — homes with lead service lines or pre-1986 plumbing can be higher.
| Monitoring period | Lead 90th percentile | vs 15 ppb action level |
|---|---|---|
| 2025-01-01 → 2025-12-01 | 7 ppb | Below the action level, but detectable |
| 2022-01-01 → 2022-12-01 | 2.5 ppb | Well below the 15 ppb action level |
| 2019-01-01 → 2019-12-01 | 1.9 ppb | Well below the 15 ppb action level |

EPA UCMR5 monitoring, 2023-07-17 to 2024-02-05 · 58 PFAS results at entry points to the distribution system
PFOA and PFOS measured at or above EPA's legal limit in at least one sample. Utilities have until 2029 (2031 under EPA's proposed extension) to comply with the 2024 PFAS rule, so a result above the MCL today is not yet a violation — but it is the number that matters for your health.
| Compound | Detects / samples | Max (ppt) | Reporting limit | EPA MCL |
|---|---|---|---|---|
| PFOA | 1 / 2 | 7.8 | 4 ppt | 4 ppt |
| PFOS | 1 / 2 | 24 | 4 ppt | 4 ppt |
| PFHxS | 1 / 2 | 5.6 | 3 ppt | 10 ppt |
| PFNA | 0 / 2 | < 4 | 4 ppt | 10 ppt |
| HFPO-DA | 0 / 2 | < 5 | 5 ppt | 10 ppt |
| PFBS | 1 / 2 | 3.5 | 3 ppt | hazard index only |
| 6:2 FTS | 1 / 2 | 89 | 5 ppt | hazard index only |
| 8:2 FTS | 1 / 2 | 5.3 | 5 ppt | hazard index only |
| PFBA | 1 / 2 | 15 | 5 ppt | hazard index only |
| PFHpA | 1 / 2 | 11 | 3 ppt | hazard index only |
| PFHxA | 1 / 2 | 28 | 3 ppt | hazard index only |
| PFPeA | 1 / 2 | 27 | 3 ppt | hazard index only |
“< 4 ppt” means below the laboratory reporting limit, not zero. ppt = parts per trillion (ng/L). Results are for finished water leaving the treatment plant.

EPA Six-Year Review 4 compliance samples for MIAMI BEACH, CITY OF · finished water only · dated data, released 2024
These are the regulated-contaminant samples MIAMI BEACH, CITY OF reported to its state between 2012 and 2019 — the most recent nationwide sample-level dataset EPA has published. Total trihalomethanes (TTHM) is flagged below; the status column explains why. Treat this as history, not today's tap water.
| Contaminant | Samples | Average | Max | EPA limit | Status |
|---|---|---|---|---|---|
| Total trihalomethanes (TTHM) | 7170 detects | 23.199 µg/L | 150.3 µg/L | 80 µg/LMCL (LRAA) | 1 single sample over MCL; average within limit |
| Haloacetic acids (HAA5) | 70 | 31.879 µg/L | 56.1 µg/L | 60 µg/LMCL (LRAA) | Within MCL |
Averages count non-detects as zero. TTHM and HAA5 limits are locational running annual averages, so a single high sample is not a violation — we grade those on the average only. Lead and copper rows are individual tap samples and are shown for context; compliance (and our score) uses the 90th-percentile result above. LRAA = locational running annual average; ND = not detected.

MIAMI BEACH, CITY OF · 9,871 service lines inventoried · Q2 2026 snapshot
MIAMI BEACH, CITY OF reports 151 service lines that are lead or galvanized-requiring-replacement (1.5% of the lines it has inventoried). A lead service line is the pipe between the water main and a building, so treated water can pick up lead after it leaves the plant — which city-level testing does not capture. Under EPA's Lead and Copper Rule Improvements, utilities must replace lead lines within 10 years starting in 2027.

Groundwater systems draw from wells; naturally occurring arsenic, nitrate, radium and uranium are the readings to watch, along with PFAS near industrial or military sites.
How to test your tap water and the treatment options that actually fit Miami Beach homes
The most reliable way to know what is actually coming out of your tap is a certified mail-in lab test. City-wide EPA data (like the report above) reflects the water leaving the treatment plant, but contaminants such as lead and copper can be picked up from your own service line and household plumbing — so the water at your Miami Beach faucet can differ from the system average. A state-certified lab measures dozens of contaminants at once with results you can trust; you can also find one near you through the EPA's certified-lab list at epa.gov/dwlabcert. Hardware-store test strips are cheaper and instant, but they only screen for a few basics (chlorine, hardness, pH, and a rough lead pass/fail) and are far less accurate — treat them as a first look, not a diagnosis.
Match the treatment to what your test finds. Reverse osmosis (RO) removes the widest range of contaminants — lead, arsenic, nitrate, PFAS, and dissolved solids — which makes an under-sink reverse osmosis system the most thorough choice for Miami Beach households with heavy-metal or PFAS concerns. If your main issue is taste, odor, or chlorine, an activated carbon filter (pitcher, faucet, or under-sink) is simpler and cheaper and handles chlorine and many organic compounds well, though carbon alone does not remove arsenic, nitrate, or most PFAS. NSF-certified pitchers rated for lead reduction are the easiest way to start today while you decide on a permanent setup.
