EPA records for FLORENCE WATER DEPARTMENT, CITY OF • Updated October 2026
Grade C — based on EPA compliance records, lead testing and PFAS monitoring
FLORENCE WATER DEPARTMENT, CITY OF has a mixed record — read the reasons below; the deductions come from real EPA violations, lead results or PFAS detections, not from a template.
Florence, AL tap water is legal to drink but grades C on EPA's records, mainly because of PFOA or PFOS measured at or above the 4 ppt federal limit in 2023–2025 EPA sampling. A certified filter matched to that finding is a reasonable precaution. The catch is lead pipes: Florence's water system reports 3,884 lead or galvanized service lines still in the ground in EPA's 2026 inventory, and lead leaches from those pipes after the water leaves the plant. If your home is on one, test at the tap or use a filter certified to NSF/ANSI 53 for lead.

FLORENCE WATER DEPARTMENT, CITY OF's most recent Lead and Copper Rule result (2023-01-01 to 2025-12-31) was 3.4 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 (2023-08-16 to 2024-06-24) detected PFBA, PFBS, PFHxA, PFOA, PFOS, with PFOA or PFOS at or above the 4 ppt federal MCL. Reverse osmosis and certified activated-carbon filters reduce PFAS.
FLORENCE WATER DEPARTMENT, CITY OF has 3 violations on file since 2016: 0 health-based in the last five years and 2 monitoring or reporting violations in that window. Monitoring violations are paperwork lapses, not measured contamination.
FLORENCE WATER DEPARTMENT, CITY OF reports surface water as its primary source and serves about 77,766 people (EPA PWSID AL0000783).
We recommend one. Reverse osmosis or a PFAS-certified carbon filter addresses the PFAS result.

EPA Lead and Copper Rule 90th-percentile results reported by FLORENCE WATER DEPARTMENT, CITY OF
Well below the 15 ppb action level. In the most recent monitoring period on file (2023-01-01 to 2025-12-31), 90% of the homes FLORENCE WATER DEPARTMENT, CITY OF sampled had lead at or below 3.4 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 |
|---|---|---|
| 2023-01-01 → 2025-12-31 | 3.4 ppb | Well below the 15 ppb action level |

EPA UCMR5 monitoring, 2023-08-16 to 2024-06-24 · 290 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 | 4 / 10 | 9.7 | 4 ppt | 4 ppt |
| PFOS | 4 / 10 | 17 | 4 ppt | 4 ppt |
| PFHxS | 0 / 10 | < 3 | 3 ppt | 10 ppt |
| PFNA | 0 / 10 | < 4 | 4 ppt | 10 ppt |
| HFPO-DA | 0 / 10 | < 5 | 5 ppt | 10 ppt |
| PFBS | 3 / 10 | 5.1 | 3 ppt | hazard index only |
| PFBA | 4 / 10 | 9.7 | 5 ppt | hazard index only |
| PFHxA | 1 / 10 | 3.2 | 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 FLORENCE WATER DEPARTMENT, CITY OF · finished water only · dated data, released 2024
These are the regulated-contaminant samples FLORENCE WATER DEPARTMENT, CITY OF reported to its state between 2012 and 2019 — the most recent nationwide sample-level dataset EPA has published. Total trihalomethanes (TTHM), Haloacetic acids (HAA5) are flagged below; the status column explains why. Treat this as history, not today's tap water.
| Contaminant | Samples | Average | Max | EPA limit | Status |
|---|---|---|---|---|---|
| Arsenic | 220 detects | 0 µg/L | ND | 10 µg/LMCL | Not detected |
| Nitrate (as N) | 3632 detects | 0.78 mg/L | 1.51 mg/L | 10 mg/LMCL | Within MCL |
| Fluoride | 2216 detects | 0.47 mg/L | 1.04 mg/L | 4 mg/LMCL | Within MCL |
| Chromium (total) | 220 detects | 0 µg/L | ND | 100 µg/LMCL | Not detected |
| Gross alpha | 54 detects | 0.86 pCi/L | 2.5 pCi/L | 15 pCi/LMCL | Within MCL |
| Total trihalomethanes (TTHM) | 506501 detects | 32.627 µg/L | 108 µg/L | 80 µg/LMCL (LRAA) | 8 single samples over MCL; average within limit |
| Haloacetic acids (HAA5) | 506498 detects | 20.216 µg/L | 88.3 µg/L | 60 µg/LMCL (LRAA) | 12 single samples over MCL; average within limit |
| Lead (tap samples) | 527 detects | 1.062 µg/L | 33 µg/L | 15 µg/Laction level (90th percentile) | Reported, not scored (compliance is on the 90th percentile) |
| Copper (tap samples) | 5233 detects | 30.117 µg/L | 227 µg/L | 1300 µg/Laction level (90th percentile) | Reported, not scored (compliance is on the 90th percentile) |
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.

FLORENCE WATER DEPARTMENT, CITY OF · 27,315 service lines inventoried · Q2 2026 snapshot
FLORENCE WATER DEPARTMENT, CITY OF reports 3,884 service lines that are lead or galvanized-requiring-replacement (14% of the lines it has inventoried), plus 17,542 lines whose material is still unknown. 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.

Surface-water systems draw from rivers, lakes or reservoirs and must filter and disinfect, which is why disinfection byproducts (TTHM, HAA5) are the readings to watch.
How to test your tap water and the treatment options that actually fit Florence 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 Florence 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 Florence 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.
