What is in the water at 73547
4 public water systems serve this ZIP code in the federal records. Everything below comes from EPA monitoring data, and everything missing is named.
OKLAHOMA STATE REFORMATORY
PWSID OK2002803 · OK · serves 999 people · service area inferred by a model, not supplied by the state
PFAS and lithium
Not sampled for PFAS. EPA’s UCMR 5 monitoring covered every system serving more than 3,300 people and only a sample of smaller ones. This system was not in it, so there is no result to show, which is not the same as a result showing nothing.
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
No hardness measurement. Hardness is measured at environmental monitoring stations, and none fell inside this system’s service area. That is a gap in where monitoring happens, not a finding about the water.

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.
