Treasure Valley water, in plain English

One valley. A lot of different water.

Nearly every community here runs on groundwater, and much of Boise also gets treated Boise River water. That’s why hardness, arsenic, nitrate and uranium vary from one city system, and one private well, to the next. We start with your water, then recommend only what it needs.

By city

Who supplies your water.

  • Ada County

    Boise

    Veolia Water Idaho

    Most Boise homes get their water from Veolia Water Idaho, which blends about 70% well water with about 30% treated Boise River water. Its 2025 report lists hardness from 13 to 219 ppm (average 105), so what comes out of your tap depends on where you live and which sources are running.

  • Ada County

    Eagle

    City of Eagle Water Department · Veolia Water Idaho

    Eagle has two main water providers, the City of Eagle Water Department and Veolia, and some homes are still on private wells. The city describes its well water as moderately hard, and its 2025 report shows uranium up to 22 ppb in the Eastern Zone, below the 30 ppb federal limit.

  • Canyon County

    Nampa

    City of Nampa

    The City of Nampa supplies groundwater to about 100,200 people, and EPA records show no violations in the latest three-year window. EWG’s 2021–2023 averages for the system include arsenic at 4.74 ppb and nitrate at 2.22 ppm, both under federal limits but above EWG’s stricter health guidelines.

  • Ada County

    Star

    Star Sewer & Water District

    Star Sewer & Water District draws from deep groundwater: a primary well about 700 feet down plus four wells deeper than 300 feet. It reported no violations in 2025, and its FAQ explains that occasional discoloration comes from naturally occurring iron and manganese, and a rotten-egg odor from hydrogen sulfide in the basalt aquifer.

  • Canyon County

    Middleton

    City of Middleton

    The City of Middleton supplies groundwater from seven wells. Its 2023 report, the latest posted, shows nitrate at 1 ppm and no detected PFAS or disinfection byproducts, and EPA records show no violations in the latest three-year window.

  • Gem County

    Emmett

    City of Emmett Public Works

    The City of Emmett supplies groundwater from three wells. Its 2025 report lists fluoride at 1.56 ppm, below the 4 ppm federal limit and the highest in our service area, and notes that its service line inventory includes some lead lines.

  • Elmore County

    Mountain Home

    City of Mountain Home Water Division

    The City of Mountain Home supplies groundwater from nine wells, and the city reports hardness of 33–55 mg/L, which is soft. That means many homes don’t need a softener at all; the more common goals are chlorine taste and drinking water, where arsenic measured 4–7 ppb in the latest report (the federal limit is 10).

Treasure Valley water questions

Call or text (602) 739-3657
Is Treasure Valley water hard?
Often, but it varies a lot. Idaho Department of Water Resources sampling found a median hardness of 189 mg/L in the shallow Treasure Valley aquifer, while utility-reported hardness ranges from soft in Mountain Home (33–55 mg/L) to 13–219 ppm across Veolia Water Idaho’s Boise sources. Your city page and a tap test tell you where your home lands.
What should private well owners test for?
Central District Health recommends testing well water every year for bacteria and nitrate. A 2019 Boise State and IDWR study found high uranium is widespread in the Treasure Valley aquifer and urged domestic well owners to test regularly. Arsenic is worth checking too. See our water testing guide.
Is PFAS regulated in Idaho?
Idaho DEQ says PFAS is not currently regulated by the state and public water systems are not required to monitor for it. Known detections in Idaho have been tied mainly to military sites such as Mountain Home Air Force Base and Gowen Field.
Do you serve Meridian, Kuna and Caldwell?
Yes, we serve communities across the Treasure Valley. Call or text (602) 739-3657 and we’ll confirm right away.
