EWG's Tap Water Database — 2019 UPDATE



Sun Valley Gid

NOTE: Sun Valley Gid purchases water from Truckee Meadows Water Authority which is required to test for vanadium. Sample information shown below was taken by Truckee Meadows Water Authority.

Vanadium is a metal used in steels and other alloys. People are commonly exposed to vanadium in water and food. Excessive exposure can be toxic during pregnancy and childhood.
