What Makes Agate Beach's Water Unique?
Local geology and source profile
Agate Beach, Oregon, in Lincoln County — a Lincoln County unincorporated community adjacent to Newport on the central Oregon coast — receives its water from the City of Newport Water, drawing from the Big Creek reservoir (Lincoln County) through the central Oregon coast distribution.
The very soft 51 mg/L hardness and low TDS of 102.3 mg/L reflect the central Oregon coast Lincoln County supply's very soft character — the Paleogene Coast Range basalt and Cretaceous Tyee Formation contribute insoluble dilution with minimal calcareous contact, typical of the Oregon Coast Range watershed communities (compare Greenwood WA: 54/120 in King County comparable; Cornelius OR: 38.5/70.9 in Washington County softer; Agate Beach similar soft Coast Range range). The Big Creek watershed at Lincoln County — Paleogene Coast Range basalt (insoluble — primary dilutant), Cretaceous Tyee Formation (insoluble — secondary dilutant), and Quaternary coastal alluvium (slightly calcareous — minor TDS).
At 51 mg/L, Agate Beach's water is very soft — scale forms very slowly in appliances, dishwashers remain efficient, and no softening is needed. Annual descaling is appropriate. The PFAS level of 1.8 ppt is very low — no filtration urgently required, warrants routine monitoring only. Agate Beach's PFAS level reflects its remote coastal Oregon location.
