Where the water comes fromSurface water in Edmonds

This is a surface water supply, which matters for hardness: the water has not spent years in an aquifer dissolving calcium out of stone. Expect a lower figure than a neighboring town on wells.

Edmonds City of serves 10,367 service connections. That count comes from the system's own filing with the EPA, current to the 2026 second-quarter refresh.

What to do with thatGet your hardness figure

You do not need a test kit to start. Edmonds City of publishes hardness in its annual water quality report, free to read. Utilities publish milligrams per liter; the trade talks in grains per gallon. Seventeen of the first make one of the second.

Then run the arithmetic: it tells you the capacity you need rather than the capacity you are offered. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
