“We built north of the river in Star and the well water was brutal — scale on everything within weeks. Aqua Source tested it, walked us through the numbers, and installed a softener that fixed it completely.”

Star Water Profile
Why Star's water is among the hardest in the valley.
Star sits on the western edge of the Treasure Valley, where homes draw water from a mix of private wells and small community systems tapping the same aquifer that runs beneath Eagle, Middleton, and Meridian. As that groundwater moves through basalt and sediment layers, it picks up substantial calcium and magnesium — the two minerals that drive water hardness.
The result is residential water averaging 15-17 grains per gallon, around 255 PPM total dissolved solids, and a slightly alkaline pH near 7.8. The USGS classifies anything above 10.5 gpg as 'very hard,' and Star sits comfortably in that range — leaving scale on fixtures, shortening appliance life, and drying out skin and hair.

★★★★★
“Added a reverse osmosis system at the kitchen sink with our whole-house softener. The drinking water finally tastes clean — no more hauling bottled water from town. Should have done it sooner.”

Star FAQ
Common questions from Star homeowners.
Why is Star's water so hard?
Star draws water from private wells and small community systems tapping the Treasure Valley aquifer. As groundwater travels through basalt and sediment beneath west Ada County, it accumulates calcium and magnesium. The result is 15-17 gpg hardness (around 255 PPM TDS) — classified as 'very hard' by USGS standards.
Do I need a water softener in Star?
If you have a private well or are on a community system in Star, almost certainly. At 16 gpg, the water causes visible scale on fixtures, shortens water heater life, and dries out skin and hair. A properly sized softener eliminates these issues and protects your appliances and plumbing.
Which Star areas do you serve?
We serve all of Star (83669) including downtown, North and South Star, the State Street and Star Road corridors, Floating Feather Road, Legacy, The Shores, Star Ranch, and every new subdivision going up around the city. Same-day estimates throughout west Ada County.
How much does a water softener cost in Star?
A professionally installed whole-house water softener in Star typically ranges from $1,800 to $3,500 depending on capacity, technology, and whether you're on a well or community system. Aqua Source publishes flat, all-in pricing — installation, materials, and warranty included — and we're currently running $200 off any softener system.
