What Makes Camano's Water Unique?
Local geology and source profile
Camano, Washington, in Island County — an Island County community on Camano Island in Puget Sound adjacent to Stanwood and Lakewood in northwest Washington — receives its water from local Camano Island water utilities, drawing from local Puget Lowland groundwater and small reservoirs (Island County) through the northwest Washington distribution.
The moderately soft 61 mg/L hardness and TDS of 143.3 mg/L reflect the northwest Washington Puget Lowland supply's moderately soft glacial character — slightly harder than the pure Cascade Mountain supplies (Elk Plain: 51.5 mg/L) due to the Camano Island supply's Puget Lowland glacial till dissolution providing more mineral input. The Camano Island watershed draws from Puget Lowland — Pleistocene Vashon Till (slightly calcareous — primary hardness contributor), Pleistocene Everson Glaciomarine Drift (calcareous), and minor local Eocene volcanic formations (insoluble).
At 61 mg/L, Camano's water is moderately soft — light scale forms slowly in appliances, dishwashers remain efficient, and bathroom fixtures need occasional cleaning. Semi-annual descaling is appropriate. The PFAS level of 2.8 ppt is very low — the Island County northwest Washington rural coastal corridor has minimal adjacent AFFF military PFAS sources.
Geology & Source: Camano in Island County draws from the Camano Island Water on local Puget Lowland groundwater and small reservoirs (Island County, northwest Washington) — the watershed drains the Puget Lowland (Pleistocene glacial till — slightly calcareous, Quaternary Vashon glaciomarine drift) — Washington Island County Camano Island Puget Lowland glacial watershed produces moderately soft water at 61 mg/L with TDS 143.3 mg/L.
