MUSKOGEE CO. RWD #1 (OKTAHA)
PWSID OK3005106 · OK · serves 2,280 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
56 open health-based violation(s) recorded in SDWIS and not yet returned to compliance.

Hardness
Too few readings to state a hardness. 1 station(s), 19 result(s). Below two stations and five results this page will not state a number: a median of two readings from one creek is not your water.

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.
