No, it’s soft.Bellevue’s water measures 1.4 gpg (24.1 mg/L as CaCO₃), in the USGS “soft” band. Hardness affects scale and appliances; it has no federal health limit.
Scale builds slowly at this level, and it isn’t a health question

What this means: Bellevue is among the softer supplies on record. Soft water leaves little scale; hardness is not a health finding either way.
City water and your tap
Hardness at your tap is usually close to the city figure.
Pipes don’t add hardness; a softener already in your home removes it. The city report gives the starting point. A test strip confirms what reaches your tap.

Check your own hardness before buying a softener.
Softener sizing depends on your gpg and household use. A test strip, or the city's report above, is enough to start. You don't need a lab for hardness.

Confirming hardness and sizing a softener
What it can’t tell you: It measures hardness only, so it tells you nothing about lead, PFAS or bacteria.
Why: it removes calcium and magnesium for every tap and appliance, the proven fix for scale. A salt-free conditioner changes how scale forms instead, without removing the minerals.

BELLEVUE CITY OF's latest water-quality report puts hardness at 1.4 grains per gallon (24.1 mg/L as calcium carbonate), which is soft. Water above about 7 gpg is generally considered hard.
How hard is Bellevue tap water in gpg?+
1.4 grains per gallon, in the USGS "soft" band. On that scale soft is below 3.5 gpg, moderately hard 3.5–7, hard 7–10.5 and very hard above 10.5.
Is hard water a health concern?+
Hardness (calcium and magnesium) has no federal health-based limit. It affects scale, soap and appliance life, not the safety of the water. Softening adds some sodium, which matters for people on low-sodium diets.
Do I need a water softener in Bellevue?+
At 1.4 gpg, most households do not need a softener; scale builds slowly at this level.
What certification should a softener have?+
NSF/ANSI 44, the standard for water softeners, checked for the exact model in the certifier's listing (NSF, WQA or IAPMO). Its "Efficiency Rated" models use less salt and regeneration water.
Does a softener remove lead or PFAS?+
No. A softener exchanges calcium and magnesium; it is not a lead or PFAS treatment. For those, use a drinking-water filter whose current certification names them, such as NSF/ANSI 53 or 58.
Can I test my own water hardness?+
Yes. A hardness test strip gives a reading in grains per gallon within minutes, which is all you need to size a softener; hardness doesn't need a lab test.
Is a salt-free conditioner enough?+
It depends on what you want. A salt-free conditioner changes how scale forms but does not remove the calcium and magnesium, so a test still reads hard. An ion-exchange softener removes them for every tap and appliance.
