What Makes Five Corners's Water Unique?
Local geology and source profile
Five Corners, Washington, in Clark County — an unincorporated Clark County community adjacent to Vancouver and Orchards, in the north Vancouver suburban corridor across the Columbia River from Portland, Oregon — receives its municipal water from Clark Public Utilities or the City of Vancouver Water Division, drawing from the Columbia River or the Bull Run Watershed supply (Portland Water Bureau regional connection).
The soft 76.5 mg/L hardness and TDS of 200.4 mg/L reflect the Clark County Columbia River supply character. The Columbia River at Vancouver-Clark County receives drainage from the Cascades (Quaternary Columbia River Basalt Group — insoluble tholeiitic basalt), the Willamette Valley (minor calcareous alluvium), and the Hood River and Sandy River volcanic drainages. The predominantly basaltic Cascade drainage produces the soft water characteristic of all lower Columbia River communities.
At 76.5 mg/L, Five Corners' water is soft — essentially no scale forms, soap lathers abundantly, and appliances maintain good efficiency. Annual descaling is sufficient. The PFAS level of 3.3 ppt warrants a certified drinking water filter — the Portland International Airport (AFFF in the Columbia River watershed), the Clark County suburban development corridor, and the lower Columbia River PFAS background contribute to Five Corners' readings.
Geology & Source: Five Corners in Clark County draws from Clark Public Utilities on the Columbia River (Clark County) or Bull Run Watershed via Portland Water Bureau — the Columbia-Willamette drains the Cascades (Quaternary basalt, Precambrian crystalline) — Washington Columbia River Cascade volcanic watershed produces soft water at 76.5 mg/L with TDS 200.4 mg/L in this Clark County Washington community.
