Newport Water Hardness & Quality Report (2026)

Newport, Oregon, in Lincoln County — the Lincoln County seat adjacent to Toledo and Waldport on the Oregon Coast — receives its water from the City of Newport Water Department, drawing from the Elk Creek watershed through the Oregon Coast distribution.

The moderately hard 93.5 mg/L hardness and TDS of 236.1 mg/L reflect the Lincoln County supply's moderate Oregon Coast Range character — the Eocene Siletz River Volcanics and Miocene Astoria Formation are largely insoluble volcanic and slightly calcareous marine formations in the Oregon Coast Range; Newport's reservoir system acquires moderate mineral content from its coastal upland geology (compare Toledo OR: 90/228 in Lincoln County comparable; Waldport OR: 96/244 in Lincoln County comparable; Newport consistent moderate from the same Lincoln County Elk Creek Eocene insoluble supply). The Elk Creek watershed — Eocene Siletz River Volcanics (insoluble — primary dilutant), Miocene Astoria Formation (slightly calcareous — primary hardness contributor), and Quaternary Oregon Coast alluvium (slightly calcareous — TDS contributor).

At 93.5 mg/L with TDS 236, Newport's water is moderately hard — mild scale buildup. Semi-annual descaling is appropriate. The PFAS level of 2.6 ppt is very low — an excellent and clean result for the Oregon Coast. Review the City of Newport's annual water quality report.
