Is hard water an issue in Edmonds, Washington—or just a plumbing myth? Many homeowners are concerned about white spots on glassware, buildup on faucets, or itchy skin after a shower. But how real is the threat of hard water here in Edmonds? Let’s break it down.
💧 What Is Hard Water, Anyway?
Hard water contains a high concentration of dissolved minerals, primarily calcium and magnesium. While these minerals aren’t harmful to human health, they can cause scale buildup in pipes, reduce the efficiency of water heaters, and wear down plumbing fixtures over time.
According to the U.S. Geological Survey (USGS), water is considered:
- Soft: 0–60 mg/L of calcium carbonate
- Moderately hard: 61–120 mg/L
- Hard: 121–180 mg/L
- Very hard: 180+ mg/L

🧪 Does Edmonds Have Hard Water?
Surprisingly, Edmonds and much of Snohomish County are not considered high in water hardness. The City of Edmonds water supply, sourced largely from the Spada Lake Reservoir via the City of Everett’s system, tends to be soft to moderately hard, typically averaging between 30–50 mg/L of calcium carbonate.
That means the average Edmonds household does not face significant hard water issues compared to regions like parts of Texas, Arizona, or Southern California.
🔍 So Why the White Spots on My Dishes?
Even with soft water, mineral spotting can still occur, especially due to:
- Evaporation of water droplets on dishes
- Old or inefficient dishwashers
- Water heaters with scale buildup
If you’re noticing white residue, it might not be traditional hard water—it could be residual minerals, or even a sign of inefficient plumbing or appliance performance.
