EPA records for EMPORIA, CITY OF • Updated October 2026
Grade B — based on EPA compliance records, lead testing and PFAS monitoring
EMPORIA, CITY OF 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 Emporia, KS tap water is safe to drink and earns a B. The grade rests on 2 health-based EPA violations in the last five years. 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.

EPA Lead and Copper Rule 90th-percentile results reported by EMPORIA, 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 EMPORIA, CITY OF sampled had lead at or below 3.33 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 | 3.32 ppb | Well below the 15 ppb action level |
| 2020-01-01 → 2022-12-31 | 4.5 ppb | Well below the 15 ppb action level |
| 2017-01-01 → 2019-12-31 | 2.8 ppb | Well below the 15 ppb action level |

EPA UCMR5 monitoring, 2024-10-22 to 2026-04-09 · 116 PFAS results at entry points to the distribution system
No PFAS detected. None of the 116 UCMR5 PFAS results for EMPORIA, CITY OF 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.

EPA Six-Year Review 4 compliance samples for EMPORIA, CITY OF · finished water only · dated data, released 2024
These are the regulated-contaminant samples EMPORIA, CITY OF 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 | 84 detects | 0.588 µg/L | 1.3 µg/L | 10 µg/LMCL | Within MCL |
| Nitrate (as N) | 1511 detects | 0.35 mg/L | 0.87 mg/L | 10 mg/LMCL | Within MCL |
| Fluoride | 4038 detects | 0.429 mg/L | 0.7 mg/L | 4 mg/LMCL | Within MCL |
| Chromium (total) | 82 detects | 0.313 µg/L | 1.5 µg/L | 100 µg/LMCL | Within MCL |
| Radium-226/228 | 10 detects | 0 pCi/L | ND | 5 pCi/LMCL | Not detected |
| Total trihalomethanes (TTHM) | 1285 detects | 0.121 µg/L | 4.9 µg/L | 80 µg/LMCL (LRAA) | Within MCL |
| Haloacetic acids (HAA5) | 12873 detects | 2.823 µg/L | 16 µg/L | 60 µg/LMCL (LRAA) | Within MCL |
| Lead (tap samples) | 9728 detects | 1.669 µg/L | 43 µg/L | 15 µg/Laction level (90th percentile) | Reported, not scored (compliance is on the 90th percentile) |
| Copper (tap samples) | 9897 detects | 19.297 µg/L | 150 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.

A point-of-use (under-sink) system typically runs $200-$600 installed; whole-house treatment $1,000-$3,000+ depending on flow and what has to come out. Tell us where you are and a certified water-treatment installer serving Emporia will follow up - no obligation.
EMPORIA, CITY OF · 9,582 service lines inventoried · Q2 2026 snapshot
EMPORIA, CITY OF reports 52 service lines that are lead or galvanized-requiring-replacement (0.5% of the lines it has inventoried), plus 7,707 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 Emporia 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 Emporia 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 Emporia 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.
