CITY OF CARROLLTON (EPA PWSID TX0570034) delivers surface water to 136,170 residents. This report reflects 29 individual PFAS result(s) from the source UCMR5 observations and the latest Lead & Copper Rule 90th-percentile result. Water hardness and disinfectant type are pending the utility's own annual report.
0health-based violations in the last 10 years
From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.
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.
Your tap can differ from the city record
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.

Choose your situation
Older buildings may have lead service lines, solder or fixtures. Lead is not in Carrollton’s published record, so only a tap test tells you. Test first-draw water, then filter if needed.
4 of 29 PFAS tested were detected in Carrollton’s record (PFBS 3.1 ng/L, PFHxA 5.3 ng/L and PFBA 8.8 ng/L, and more). If PFAS matters to you, a filter certification names each compound it covers.
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.
Your utility’s annual water quality report usually lists hardness; a test strip also measures it.
Reverse osmosis reduces many dissolved contaminants, including lead and minerals, at a single faucet, with some water sent to drain.

How PurityMap reads Carrollton’s water
- 01Source data
EPA SDWIS, EPA UCMR 5 and utility reports, each dated and linked.
- 02Normalize
Units converted to one basis; a non-detect kept distinct from zero.
- 03Classify
Each result tagged by reference type: MCL, action level, screening level or aesthetic.
- 04Compare to the named reference
Every value sits against its own reference, never a blended one.
- 05Score
Measured subjects summarised at the water-system level; an open health-based violation caps the score.
- 06Match treatment
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 CARROLLTON · PWSID TX0570034 · Purity Score 100/100 (Excellent) · Confidence: moderate · Assessed at the water-system level
Full methodology →Something off with your water's smell, color or taste?
Start with the hot-or-cold tap check. Where City of Carrollton reported something related, it's shown below.
- Rotten-egg smell
- Cloudy or milky water
- Chlorine smell
- Brown or yellow water
- Metallic taste
Lead at City of Carrollton: not detected (90th percentile, 2023–2025 monitoring period). Lead has no taste, so a taste neither shows nor rules it out.
