EPA records for MOA MUNICIPALITY OF ANCHORAGE • Updated September 2026
Grade B — based on EPA compliance records, lead testing and PFAS monitoring
MOA MUNICIPALITY OF ANCHORAGE is in good standing with EPA, with only minor deductions for monitoring paperwork, low-level PFAS or historical readings near a limit.
Yes — by EPA's records Anchorage, AK tap water is safe to drink and earns a B. The grade rests on PFOA or PFOS measured at or above the 4 ppt federal limit in 2023–2025 EPA sampling. Lead from your own service line or plumbing is the main risk city-level data cannot see, so homes built before 1986 should still test at the tap.

MOA MUNICIPALITY OF ANCHORAGE's most recent Lead and Copper Rule result (2022-01-01 to 2024-12-31) was 0 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 (2023-01-23 to 2023-10-03) detected PFHxS, PFOA, with PFOA or PFOS at or above the 4 ppt federal MCL. Reverse osmosis and certified activated-carbon filters reduce PFAS.
MOA MUNICIPALITY OF ANCHORAGE has 9 violations on file since 2016: 0 health-based in the last five years and 3 monitoring or reporting violations in that window. Monitoring violations are paperwork lapses, not measured contamination.
MOA MUNICIPALITY OF ANCHORAGE reports surface water as its primary source and serves about 221,351 people (EPA PWSID AK2210906).
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 MOA MUNICIPALITY OF ANCHORAGE
Well below the 15 ppb action level. In the most recent monitoring period on file (2022-01-01 to 2024-12-31), 90% of the homes MOA MUNICIPALITY OF ANCHORAGE sampled had lead at or below 0 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.

|---|---|---|
| 2022-01-01 → 2024-12-31 | 0 ppb | Well below the 15 ppb action level |

EPA UCMR5 monitoring, 2023-01-23 to 2023-10-03 · 696 PFAS results at entry points to the distribution system
PFOA and PFHxS 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 / 24 | 9.1 | 4 ppt | 4 ppt |
| PFOS | 0 / 24 | < 4 | 4 ppt | 4 ppt |
| PFHxS | 4 / 24 | 11.2 | 3 ppt | 10 ppt |
| PFNA | 0 / 24 | < 4 | 4 ppt | 10 ppt |
| HFPO-DA | 0 / 24 | < 5 | 5 ppt | 10 ppt |
| PFBS | 0 / 24 | < 3 | 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 MOA MUNICIPALITY OF ANCHORAGE · finished water only · dated data, released 2024
These are the regulated-contaminant samples MOA MUNICIPALITY OF ANCHORAGE reported to its state between 2012 and 2019 — the most recent nationwide sample-level dataset EPA has published. Haloacetic acids (HAA5) is flagged below; the status column explains why. Treat this as history, not today's tap water.
| Contaminant | Samples | Average | Max | EPA limit | Status |
|---|---|---|---|---|---|
| Arsenic | 130 detects | 0 µg/L | ND | 10 µg/LMCL | Not detected |
| Nitrate (as N) | 1211 detects | 0.559 mg/L | 1.69 mg/L | 10 mg/LMCL | Within MCL |
| Fluoride | 155 detects | 0.104 mg/L | 0.66 mg/L | 4 mg/LMCL | Within MCL |
| Chromium (total) | 139 detects | 1.131 µg/L | 2.8 µg/L | 100 µg/LMCL | Within MCL |
| Radium-226/228 | 10 detects | 0 pCi/L | ND | 5 pCi/LMCL | Not detected |
| Total trihalomethanes (TTHM) | 254221 detects | 6.409 µg/L | 68.3 µg/L | 80 µg/LMCL (LRAA) | Within MCL |
| Haloacetic acids (HAA5) | 255231 detects | 4.909 µg/L | 74 µg/L | 60 µg/LMCL (LRAA) | 1 single sample over MCL; average within limit |
| Lead (tap samples) | 18346 detects | 0.583 µg/L | 32 µg/L | 15 µg/Laction level (90th percentile) | Reported, not scored (compliance is on the 90th percentile) |
| Copper (tap samples) | 165156 detects | 39.586 µg/L | 212 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.

MOA MUNICIPALITY OF ANCHORAGE · 56,371 service lines inventoried · Q2 2026 snapshot
MOA MUNICIPALITY OF ANCHORAGE reports no confirmed lead service lines, but 15,451 lines (27%) have not yet been verified, so lead cannot be ruled out for those homes. Utilities must keep investigating unknown lines under EPA's Lead and Copper Rule Improvements.

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 Anchorage 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 Anchorage 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 Anchorage 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.
