What Makes Lakeland North's Water Unique?
Local geology and source profile
Lakeland North, Washington, in King County — a King County community adjacent to Auburn and Federal Way in south King County — receives its water from Seattle Public Utilities, drawing from the Cedar River or Tolt River reservoir (King County) through the south King County distribution.
The very soft 46.5 mg/L hardness and low TDS of 97.2 mg/L reflect the south King County SPU Cedar-Tolt supply's very soft character — slightly harder than typical SPU values (Lake Forest Park WA: 21.5 mg/L) from local Puget Sound lowland glacial aquifer blending, consistent with other south King County SPU communities (compare Kingsgate WA: 79.5 mg/L). The Cedar-Tolt watershed at King County — Oligocene Cascade volcanic (insoluble — SPU component dilutant), Pleistocene Puget Lowland glacial aquifer (slightly calcareous — minor hardness contributor), and Quaternary valley alluvium (slightly calcareous — minor TDS).
At 46.5 mg/L, Lakeland North'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 2.3 ppt is very low — warrants routine monitoring but no urgent filtration.
Geology & Source: Lakeland North in King County draws from the Seattle Public Utilities on Cedar River or Tolt River reservoirs (King County, south King County, Washington) — the Cedar-Tolt watershed drains the Cascade Range (Oligocene Stevens Ridge Formation — insoluble) and Quaternary Cascade volcanic basalt (insoluble) — Washington King County Cedar-Tolt Cascade insoluble volcanic supply produces very soft water at 46.5 mg/L with TDS 97.2 mg/L.
