What is in the water at 15201

One public water system serves this ZIP code in the federal records. Everything below comes from EPA monitoring data, and everything missing is named.

PITTSBURGH WATER & SEWER AUTH

PWSID PA5020038 · PA · serves 520,000 people

PFAS and lithium

Sampled, nothing detected. Tested for 30 compounds under UCMR 5 with none found at or above its reporting limit. A reporting limit is the lowest concentration the method can measure, so this means “below that” rather than “zero”.

Health-based violations

No open health-based violation on record. This covers MCL, treatment technique and MRDL violations in SDWIS that have not been returned to compliance. It excludes monitoring and reporting violations, which are the large majority nationally, so this is not “no violations”, and SDWIS completeness varies by state.

Hardness

We do not state a hardness for any system, and this is why. Hardness here would come from environmental monitoring stations that happen to sit inside your water system’s service area. We checked that method against the figures twenty large utilities publish about their own supply: it agreed with the utility fewer than half the time, and where it was wrong it usually read HIGH. Cities supplied from a distant watershed came off worst, because the stations end up sampling local groundwater nobody drinks. We are paid a referral fee when somebody asks for an installer, so a number that overstates hardness is the last error we are willing to publish. Your utility publishes its own hardness in its annual water quality report, and that figure is the one to trust.

What this report cannot tell you

Every figure describes water at a sampling point: a treatment plant, an entry point to the distribution system, or a monitoring station. None of it describes water arriving at your tap. Plumbing between the two can add lead and copper, and if your home was built before 1986 a test kit tells you something no federal dataset can.
