Showing the 12 largest of 54 active systems serving the county. Health-based violations are shown alone — administrative (paperwork) records are counted separately and never added in, because most violation records are paperwork.
No public dataset can establish that any tap is safe or unsafe — records have gaps, lag by up to a quarter, and say nothing about a building's own plumbing or private wells.
What the records do show: 54 active water systems serve Johnston County. 10 of them currently have an unresolved health-based violation on record. Health-based violations are counted separately from paperwork violations, which make up most records.
State assessments under the Clean Water Act list Pigeon House Branch as not supporting recreation. That is an official determination about the waterway, not a measurement taken today.
36 of the county's waterways on record have never been assessed for swimming — their condition is unknown.

Records lag their agencies' refresh cycles — a recent change may not appear yet. Absence from a dataset is absence of a record, never evidence that water is clean.
The interactive report adds the map, monitoring-station samples, permitted operations in connected watersheds, and plain-language explanations of every term.
