What Makes Lakeland South's Water Unique?
Local geology and source profile
Lakeland South, Washington, in King County — a King County census-designated place adjacent to Auburn and Pacific in south King County — receives its water from Tacoma Public Utilities or Lakehaven Water and Sewer District, drawing from the Green River watershed through the west Washington distribution.
The very soft 46.5 mg/L hardness and low TDS of 97.2 mg/L reflect the King County Green River supply's very soft Cascade volcanic character — the Quaternary Cascade volcanic deposits (andesite, basalt) are highly insoluble, and the Tertiary Puget Sound sediments contribute only minor calcareous content from marine shells (compare Auburn WA: 45/94 in King County comparable; Pacific WA: 48/100 in King County comparable; Lakeland South consistent very soft from the same King County Green River Cascade volcanic supply). The Green River at King County — Quaternary Cascade volcanic deposits (insoluble — primary dilutant), Tertiary Puget Sound sediments (slightly calcareous — primary hardness contributor), and Holocene Green River alluvium (insoluble — minimal TDS).
At 46.5 mg/L with TDS 97, Lakeland South's water is very soft — virtually no scale buildup. Annual descaling is appropriate. The PFAS level of 2.3 ppt is low — a clean result for the south King County area. Review Tacoma Public Utilities' or Lakehaven's annual water quality report for the latest data.
Geology & Source: Lakeland South in King County draws from the Tacoma Public Utilities on Green River reservoir (King County, west Washington) — the Green River at King County drains Quaternary Cascade volcanic deposits (insoluble) and Tertiary Puget Sound sediments (slightly calcareous) — Washington King County Green River Cascade volcanic supply produces very soft water at 46.5 mg/L with TDS 97.2 mg/L.
