EPA records for PUEBLO BOARD OF WW • Updated September 2026
Grade A — based on EPA compliance records, lead testing and PFAS monitoring
PUEBLO BOARD OF WW has a clean recent record: no health-based violations in the last five years and no lead, PFAS or historical monitoring result that costs it more than a few points.
Yes — by EPA's records, Pueblo's tap water earns a A: no health-based violations in five years, lead at 2.3 ppb (90th percentile) and no PFAS detected. Lead from home plumbing is the main remaining risk.
By EPA's records, yes. PUEBLO BOARD OF WW earns a A: no health-based violations in the last five years, a lead 90th-percentile result of 2.3 ppb, and no PFAS detected in UCMR5 sampling. Lead from your own plumbing is the main risk city data cannot see.
PUEBLO BOARD OF WW's most recent Lead and Copper Rule result (2023-01-01 to 2025-12-31) was 2.3 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.
No. None of the 116 UCMR5 PFAS results for PUEBLO BOARD OF WW (2024-06-17 to 2025-03-22) were at or above the reporting limit of roughly 3–5 ppt.
PUEBLO BOARD OF WW has 2 violations on file since 2016: 0 health-based in the last five years and 0 monitoring or reporting violations in that window. Monitoring violations are paperwork lapses, not measured contamination.
PUEBLO BOARD OF WW reports surface water as its primary source and serves about 114,070 people (EPA PWSID CO0151500).
Not on the strength of EPA's data for PUEBLO BOARD OF WW. A filter still helps with taste and with lead from your own plumbing, which no city-level test can measure.

EPA Lead and Copper Rule 90th-percentile results reported by PUEBLO BOARD OF WW
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 PUEBLO BOARD OF WW sampled had lead at or below 2.3 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 | 2.3 ppb | Well below the 15 ppb action level |
| 2021-01-01 → 2021-12-31 | 2.3 ppb | Well below the 15 ppb action level |
| 2020-01-01 → 2020-12-31 | 2.4 ppb | Well below the 15 ppb action level |
| 2019-01-01 → 2019-12-31 | 2.5 ppb | Well below the 15 ppb action level |
| 2018-01-01 → 2018-12-31 | 2 ppb | Well below the 15 ppb action level |
| 2017-01-01 → 2017-12-31 | 5.2 ppb | Below the action level, but detectable |

EPA UCMR5 monitoring, 2024-06-17 to 2025-03-22 · 116 PFAS results at entry points to the distribution system
No PFAS detected. None of the 116 UCMR5 PFAS results for PUEBLO BOARD OF WW were at or above the method reporting limit. Reporting limits are about 3–5 ppt, so “not detected” means below that threshold — not proven zero.
| Compound | Detects / samples | Max (ppt) | Reporting limit | EPA MCL |
|---|---|---|---|---|
| PFOA | 0 / 4 | < 4 | 4 ppt | 4 ppt |
| PFOS | 0 / 4 | < 4 | 4 ppt | 4 ppt |
| PFHxS | 0 / 4 | < 3 | 3 ppt | 10 ppt |
| PFNA | 0 / 4 | < 4 | 4 ppt | 10 ppt |
| HFPO-DA | 0 / 4 | < 5 | 5 ppt | 10 ppt |
| PFBS | 0 / 4 | < 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.
Lithium (also monitored under UCMR5, not a PFAS): detected in 4 of 4 samples, max 14.3 µg/L. There is no federal limit for lithium.

EPA Six-Year Review 4 compliance samples for PUEBLO BOARD OF WW · finished water only · dated data, released 2024
These are the regulated-contaminant samples PUEBLO BOARD OF WW reported to its state between 2012 and 2019 — the most recent nationwide sample-level dataset EPA has published. Every scored contaminant stayed within its Maximum Contaminant Level (MCL) and averaged below 80% of the limit. Treat this as history, not today's tap water.
| Contaminant | Samples | Average | Max | EPA limit | Status |
|---|---|---|---|---|---|
| Arsenic | 80 detects | 0 µg/L | ND | 10 µg/LMCL | Not detected |
| Nitrate (as N) | 87 detects | 0.258 mg/L | 0.54 mg/L | 10 mg/LMCL | Within MCL |
| Fluoride | 32 | 0.819 mg/L | 3.43 mg/L | 4 mg/LMCL | Within MCL |
| Chromium (total) | 83 detects | 0.468 µg/L | 1.37 µg/L | 100 µg/LMCL | Within MCL |
| Uranium (combined) | 3 | 2.933 µg/L | 3.6 µg/L | 30 µg/LMCL | Within MCL |
| Radium-226/228 | 2 | 0.35 pCi/L | 0.4 pCi/L | 5 pCi/LMCL | Within MCL |
| Gross alpha | 3 | 1.401 pCi/L | 2.688 pCi/L | 15 pCi/LMCL | Within MCL |
| Total trihalomethanes (TTHM) | 189 | 8.488 µg/L | 24.2 µg/L | 80 µg/LMCL (LRAA) | Within MCL |
| Haloacetic acids (HAA5) | 188 | 12.873 µg/L | 48.8 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.

PUEBLO BOARD OF WW · 41,252 service lines inventoried · Q2 2026 snapshot
PUEBLO BOARD OF WW reports 176 service lines that are lead or galvanized-requiring-replacement (0.4% of the lines it has inventoried), plus 21,048 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 Pueblo 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 Pueblo 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 Pueblo 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.
