EPA records for UNION CITY • Updated September 2026
Grade F — based on EPA compliance records, lead testing and PFAS monitoring
UNION CITY has serious issues in EPA's records: repeated health-based violations, unresolved violations, PFAS above the federal limit or lead near the action level. We recommend filtering drinking water.
Union City, GA tap water is legal to drink but grades F on EPA's records, mainly because of 5 health-based EPA violations in the last five years and low-level PFAS (PFBS, PFHxA, PFPeA) detected below federal limits. A certified filter matched to those findings is a reasonable precaution.
Union City, GA tap water is legal to drink but grades F on EPA's records, mainly because of 5 health-based EPA violations in the last five years and low-level PFAS (PFBS, PFHxA, PFPeA) detected below federal limits. A certified filter matched to those findings is a reasonable precaution.
UNION CITY's most recent Lead and Copper Rule result (2003-01-01 to 2003-12-31) was 4.2 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 (2025-11-20 to 2026-06-17) detected PFBS, PFHxA, PFPeA, all below federal MCLs. Reverse osmosis and certified activated-carbon filters reduce PFAS.
UNION CITY has 14 violations on file since 2016: 5 health-based in the last five years and 0 monitoring or reporting violations in that window. Monitoring violations are paperwork lapses, not measured contamination.
UNION CITY reports purchased surface water as its primary source and serves about 18,636 people (EPA PWSID GA1210010).
We recommend one. Check which contaminant the violations involved (table above) and choose a filter certified for it.

UNION CITY · SDWIS records since 2016 · 5-year window starts 2021-09-13
EPA records 5 health-based violations for this system in the last five years, all of which are marked resolved or archived. Health-based violations mean a contaminant exceeded its Maximum Contaminant Level (MCL) or a required treatment step was not met.

EPA Lead and Copper Rule 90th-percentile results reported by UNION CITY
Well below the 15 ppb action level. In the most recent monitoring period on file (2003-01-01 to 2003-12-31), 90% of the homes UNION CITY sampled had lead at or below 4.2 ppb. This result is from before 2020, so it is shown for context but not scored.
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 |
|---|---|---|
| 2003-01-01 → 2003-12-31 | 4.2 ppb | Well below the 15 ppb action level |
| 2002-01-01 → 2002-12-31 | 2.5 ppb | Well below the 15 ppb action level |
| 2001-01-01 → 2001-12-31 | 4.53 ppb | Well below the 15 ppb action level |

EPA UCMR5 monitoring, 2025-11-20 to 2026-06-17 · 116 PFAS results at entry points to the distribution system
PFBS, PFHxA, PFPeA detected at low levels; no compound was at or above its federal MCL. Detections below the MCL are common in surface-water systems and are reported here exactly as EPA published them.
| 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 | 1 / 4 | 3.4 | 3 ppt | hazard index only |
| PFHxA | 3 / 4 | 3.7 | 3 ppt | hazard index only |
| PFPeA | 3 / 4 | 3.5 | 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.

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 Union City will follow up - no obligation.
UNION CITY · 6,041 service lines inventoried · Q2 2026 snapshot
UNION CITY reports no lead or galvanized-requiring-replacement service lines and has classified 100% of its 6,041 lines as non-lead. Lead can still come from pre-1986 plumbing and fixtures inside a home.

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 Union City 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 Union City 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 Union City 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.
