What Makes Newberg's Water Unique?
Local geology and source profile
Newberg, Oregon, in Yamhill County in the Willamette Valley wine country between Portland and Salem — home to George Fox University and surrounded by world-renowned Pinot Noir vineyards in the Chehalem Mountains AVA — receives its municipal water from the City of Newberg Public Works Water Division, drawing from the Willamette River at a treatment plant on the city's southern edge. Newberg draws from the Willamette River corridor that also serves communities throughout the Willamette Valley floor.
The moderately soft 93.5 mg/L hardness and TDS of 235.1 mg/L reflect the Willamette River's blended watershed geology entering the valley floor from the western foothills. The Willamette at Newberg carries water from the Chehalem Mountains — underlain by the Eocene Siletz River Volcanics (Paleocene-Eocene ocean floor basalts), Tyee Formation marine turbidite sandstone, and the Columbia River Basalt Group flows capping the coastal hills — all volcanic and marine sedimentary terrains with moderate mineral content compared to calcareous regions. The Willamette Valley floor's alluvial deposits add some dissolved mineral contribution, producing a finished supply that is moderately soft by Pacific Northwest standards.
At 93.5 mg/L, Newberg's water is moderately soft — comfortable for everyday household use in this Willamette Valley community. Scale forms gradually over months in kettles and appliances, soap lathers well, and the dishwasher produces clean results without special treatment. Quarterly descaling of heating appliances is adequate. The PFAS level of 2.6 ppt is excellent — Newberg's agricultural-residential Yamhill County character, with limited industrial and military PFAS sources in the watershed, produces one of Oregon's better municipal PFAS readings. The Chehalem Mountains wine country watershed protection further buffers the supply from PFAS inputs.
Geology & Source: Newberg in Yamhill County draws from the Newberg Water Treatment Facility on the Willamette River or Chehalem Creek — the Chehalem watershed drains the Chehalem Mountains and Tualatin Valley over Eocene Siletz River Volcanics (Columbia River Basalt-related) and Paleocene-Eocene marine sedimentary rocks — volcanic and marine sedimentary watershed drainage produces moderately soft water at 93.5 mg/L in this Yamhill County wine country community.
