Short answer: In the 2023–2026 records we hold for Abilene, three PFAS, PFHxS, PFOA and PFOS, each had a sample above a 2024 EPA limit (not a violation: the limits are judged on a yearly average, due 2029), and a health-based violation is on record (EPA SDWIS). Also worth knowing: lithium sits above a screening level, and the water is very hard. 11 substances were detected and 21 were tested and not detected. The water is from City of Abilene, serving 130,501 residents.
Plumbing inside the building is outside this record.

① · Measured
30 ng/L, sampled 2023-09-13 to 2024-06-12. EPA UCMR 5.
② · Compared
4.0 ng/L federal MCL (2024): a legal limit. That limit is judged on a yearly average, and water systems have until 2029 to meet it, so a single sample is not a violation. EPA health goal (MCLG): 0.
③ · Meaning
One EPA sample measured 30 ng/L, above the 4 ng/L limit EPA set in 2024. That limit is judged on a yearly average, and water systems have until 2029 to meet it, so a single sample is not a violation.
④ · Where it matters
Comes with the source water; home plumbing does not add it.
⑤ · What to do
Test your own tap first. To reduce it: Reverse osmosis, or carbon certified for PFAS (NSF/ANSI 53 or 58 (PFOA/PFOS)).

Aesthetic, no federal health limit.
③ · Meaning
188–224 mg/L as CaCO3 (11.0–13.1 grains/gal) across the system; very hard at the midpoint (206 mg/L). Aesthetic (scale/appliances), not a health finding.

Track record
1health-based violation in the last 10 years
From EPA SDWIS. Counted once per contaminant per year, as in the Track record score.
Not in this recordDisinfection by-products weren't monitored in this dataset
No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.
Health-based violations, last 10 years
Every filing is listed; the Track record score counts at most one per contaminant per year.
The record describes water leaving treatment and samples across the system. Pipes, solder and fixtures inside a building can add lead the record can’t see, especially in older buildings with lead service lines.

Lead service lines
Ask your utility first
City of Abilene reported 2,157 galvanized service lines to replace in EPA’s inventory (2026Q2). Many utilities replace these lines for free or share the cost. Ask City of Abilene whether your home’s line is on its list before you pay anyone.
Your path: I live in an older buildingLead from plumbing is the main question
Older buildings may have lead service lines, solder or fixtures. Abilene’s utility reported 2,157 galvanized service lines in EPA’s inventory. Test first-draw water, then filter if needed.
9 of 29 PFAS tested were detected in Abilene’s record (PFOS 30 ng/L, PFHxS 32.4 ng/L and PFOA 7.7 ng/L, and more); 3 above their limit. If PFAS matters to you, a filter certification names each compound it covers.
Look forNSF/ANSI 53 or 58, with each compound you care about named on the listing
Your path: My water tastes of chlorineThe disinfectant is not in this record
Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Abilene, PFOS 30 ng/L (limit 4 ng/L), PFHxS 32.4 ng/L (limit 10 ng/L) and PFOA 7.7 ng/L (limit 4 ng/L) were measured in one EPA sample each, above the limits EPA set in 2024 (not a violation: the limits are judged on a yearly average, due 2029). CITY OF ABILENE (PWSID TX2210001) has a Purity Score of 56/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap. What we found →

Are PFAS "forever chemicals" in Abilene's water?+
Yes. In EPA's UCMR 5 testing (2023-09-13 to 2024-06-12), PFOS was measured at 30 ng/L in one EPA sample, above the 4 ng/L limit EPA set in 2024, PFHxS was measured at 32.4 ng/L in one EPA sample, above the 10 ng/L limit EPA set in 2024 and PFOA was measured at 7.7 ng/L in one EPA sample, above the 4 ng/L limit EPA set in 2024. EPA's 2024 limits are judged on a yearly average, and water systems have until 2029 to meet them, so a single sample is not a violation. PFBS (8.2 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (23.5 ng/L, below the 400,000 ng/L state limit) were also detected. PFBA (43.1 ng/L), PFHpA (12.4 ng/L), PFPeA (22.9 ng/L) and PFPeS (4.5 ng/L) were also detected; they have no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap. What we found →

Treatment is matched to what was found; a product is called certified only when its current certification names it.
What the Purity Score means: a summary of this water system’s published record, capped while a health-based violation is open. It is not a test of any tap. CITY OF ABILENE · PWSID TX2210001 · Purity Score 56/100 (Fair) · Confidence: moderate · Assessed at the water-system level
Lead at City of Abilene: not detected (90th percentile, 2024–2026 monitoring period (still open)). Lead has no taste, so a taste neither shows nor rules it out.
