It serves approximately 723 people in Harrisburg, OR, and is subject to primacy enforcement by the Oregon drinking-water program.

A historical violation does not necessarily describe current water quality, systems must notify customers and remediate, and monitoring-type violations often reflect reporting lapses rather than contamination. The most authoritative real-time source is the utility's annual Consumer Confidence Report.
