Short answer: In the 2024–2025 records we hold for Pittsburgh, no listed result is above a legal limit, but 2 health-based violations are on record (EPA SDWIS). 1 substance was detected and 30 were tested and not detected. The water is from Pittsburgh Water and Sewer Authority, serving 520,000 residents.
Your water bill or annual water quality report names your actual supplier.
Also supplies: Millvale, Sharpsburg
Surface water
The treatment details are not on record.
Mains, then your building’s service line.
Plumbing inside the building is outside this record.
No measured result is above a legal limit.
2 µg/L, sampled 2025–2025 monitoring period. EPA SDWIS (Lead & Copper Rule).
15 µg/L federal action level. EPA health goal (MCLG): 0.
The 90th-percentile tap result was 2.0 µg/L (below the 15 µg/L action level).
Usually from lead service lines, solder and fixtures inside buildings, after the water leaves treatment.
Test your own tap first. To reduce it: Lead-certified carbon filter, or reverse osmosis (NSF/ANSI 53 (lead)).
PITTSBURGH WATER & SEWER AUTH (EPA PWSID PA5020038) delivers surface water to 520,000 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.
2health-based violations in the last 10 years
From EPA SDWIS. Counted once per contaminant per year, as in the Track record score.
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.
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.

Lab-certified results
ETR Laboratories
50+ substances, including lead, copper, arsenic, nitrate, hardness and coliform bacteria
What it can't tell you: It does not test PFAS, and not every result on the panel falls under the lab's accredited scope.
Screening: quick check, not lab-grade
Safe Home (EnviroTestKits)
Lead, read as one of three ranges: 0–4, 5–15 or 15+ ppb
What it can't tell you: It shows a lead range, not an exact level, and tests nothing else unless you pay extra for the optional lab test.

Lead service lines
Pittsburgh Water and Sewer Authority reported 16,165 lead and 2,250 galvanized service lines to replace in EPA’s inventory (2026Q2). Many utilities replace these lines for free or share the cost. Ask Pittsburgh Water and Sewer Authority whether your home’s line is on its list before you pay anyone.
Local help
Call to be connected with a local plumbing provider about lead service lines, repiping or fixture replacement.
Older buildings may have lead service lines, solder or fixtures. Pittsburgh’s record shows lead at 2 µg/L (15 µg/L federal action level). Test first-draw water, then filter if needed.
None of the 29 PFAS tested was detected in Pittsburgh’s record. 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.
Get one email when Pittsburgh’s record changes.
One email when a new sampling round is published, a result moves above or below its reference, or the system's score changes.PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Pittsburgh, no regulated PFAS were detected in EPA's 2024 testing; the lead 90th-percentile result was 2 µg/L against the 15 µg/L action level. PITTSBURGH WATER & SEWER AUTH (PWSID PA5020038) has a Purity Score of 96/100 (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 →
PITTSBURGH WATER & SEWER AUTH (PWS ID PA5020038) is the public water system on record for Pittsburgh, Pennsylvania, serving about 520,000 people. Confirm the utility on your water bill before acting on a specific finding. Water utility →

None of the 29 PFAS in EPA's UCMR 5 testing (2024-02-13 to 2024-10-30) was detected. "Not detected" means below the lab's reporting limit, not proven zero. What we found →
PITTSBURGH WATER & SEWER AUTH's most recent lead 90th-percentile result (2025) was 2 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink. Your household →
PurityMap's current record for Pittsburgh holds 31 findings: 1 detected within the reference and 30 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass. Records →

Methodology: how we analyze water. Prepared with AI assistance and reviewed by the PurityMap Editorial Team before publication.
EPA SDWIS, EPA UCMR 5 and utility reports, each dated and linked.
Units converted to one basis; a non-detect kept distinct from zero.
Each result tagged by reference type: MCL, action level, screening level or aesthetic.
Every value sits against its own reference, never a blended one.
Measured subjects summarised at the water-system level; an open health-based violation caps the score.
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. PITTSBURGH WATER & SEWER AUTH · PWSID PA5020038 · Purity Score 96/100 (Excellent) · Confidence: moderate · Assessed at the water-system level
