Strontium
Sun Valley Gid
NOTE: Sun Valley Gid purchases water from Truckee Meadows Water Authority which is required to test for strontium. Sample information shown below was taken by Truckee Meadows Water Authority.
Strontium is a metal that accumulates in the bones. Radioactive strontium-90 can cause bone cancer and leukemia, and any form of strontium at high doses can harm bone health.
