Why test for lead in Idaho

On a private well, lead almost always comes from the metal the water touches on its way to your glass, and corrosive water decides how much. Read our lead explainer.

Idaho guidance that mentions lead:

• DHW offers free private well water testing (listed as available fall 2026) while funding is available. Idaho residents sign up through DHW's Idaho Health Tools website to have a free kit mailed home. The test covers nitrate, fluoride, arsenic, lead, uranium, manganese, chromium, nickel, copper, zinc, selenium, cadmium and barium, and results come with guidance on next steps. DHW says that because of the volume of kits being processed, it may take up to two months. [1]

Prices at Idaho Bureau of Laboratories, Drinking Water Analysis Submission Form, Private Well Owner, revised 08/21/2024 (prices as printed; gross alpha and beta is by quote). The form says lab fees are also posted at StateLab.idaho.gov; IBL's Sampling and Submission Guide was not read., as published when checked on 3 Nov 2026. Private certified labs set their own prices.

About 396,215 people in Idaho used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [3] Federal limits are written for public water systems, not private wells, so testing is up to the owner.

For tests that depend on your home (farms nearby, old plumbing, a new baby), use the which-tests checklist. When results arrive, check your numbers against EPA's limits. State guidance, county data and every lab: Idaho.
