We don't have system-level data for Onaga yet
Our dataset doesn't currently include the EPA testing and violation records for the water systems serving Onaga, so we're not publishing a safety score for it — a score we can't show the evidence for isn't worth anything to you.
The two authoritative sources are your utility's annual Consumer Confidence Report, which it is legally required to send you, and EPA's CCR search. Meanwhile, the Kansas state overview and the filtration guides below still apply.

Onaga Water Quality Summary
We don't currently hold EPA SDWIS system-level records for Onaga, KS, so this page doesn't assign the city a water quality score. Scoring a city's drinking water without the underlying testing and violation records would be guesswork dressed up as data, and on a question this consequential that's worse than saying nothing.
What is worth knowing: every community water system in the United States must publish a Consumer Confidence Report each year listing every contaminant detected and the level found. That report covers your address specifically, which no citywide average can do. Request it from your utility, or look it up through EPA's CCR search. Our Kansas state overview covers the broader regional picture.
