Kuna Water Profile
Kuna has the hardest residential water in Ada County.
Kuna sits on shallow alluvial groundwater that draws from the base of the Snake River Plain Aquifer. Unlike Boise's deeper wells, Kuna's water source sits closer to agricultural land and picks up higher concentrations of calcium, magnesium, and dissolved minerals.
At 18–20 grains per gallon and 300+ PPM TDS, Kuna's water is classified as 'extremely hard' by some industry standards. New Kuna homeowners frequently contact us within the first year after discovering scale buildup and appliance issues that came with the water.

Kuna FAQ
Common questions from Kuna homeowners.
Why is Kuna's water so hard?
Kuna sits on shallow alluvial groundwater from the Snake River Plain Aquifer, positioned close to agricultural land with naturally high mineral content. This produces some of Ada County's hardest residential water — typically 18–20 gpg and 300+ PPM TDS.
Do I need a water softener in Kuna?
More than almost anywhere in the valley, yes. Kuna's extremely hard water causes rapid scale buildup in pipes and appliances, shortens water heater life significantly, and creates visible mineral deposits on fixtures and glassware within weeks.
Do you service all of Kuna?
Yes — we serve all of Kuna (83634) including downtown, North and South Kuna, Blackrock, River Valley, Maple Grove area, and all surrounding communities. Same-day estimates throughout Ada County.
How much does a water softener cost in Kuna?
Because Kuna's water is among the hardest in the valley, we typically recommend higher-capacity systems. Pricing ranges from $2,000 to $3,800 all-in. Aqua Source uses flat transparent pricing with no hidden costs.
