Match the report year and cited system statement to the question.
DOWNTOWN SEATTLE / GUIDE
Read Seattle's Water Quality Report
Separate official supply information from private service, building storage, risers, fixtures, treatment devices, and local work.
PRACTICAL GUIDE
Read the report at the correct scale
Use the current SPU system report for system-level facts, not a diagnosis of one fixture or building.
A web page cannot decide health, cause, or sampling needs for one property.
Keep property questions separate
Match the report year, system, source, sampling context, and exact statement to the question being asked. SPU's system-level reporting does not determine what happened inside a private service, building tank, riser, fixture, treatment device, or one sample location.
Use current official health and utility guidance when a property-specific concern needs testing or use advice.
