EWG's Tap Water Database — 2019 UPDATE



Jackson County PWSD1

NOTE: Jackson County PWSD1 purchases water from Kansas City which is required to test for strontium. Sample information shown below was taken by Kansas City.

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.

State and national drinking water standards and health guidelines

EWG Health Guideline 1,500 ppb

The EWG Health Guideline of 1,500 ppb for strontium was defined by the Environmental Protection Agency as a benchmark for testing under the Unregulated Contaminant Monitoring Rule program. This health guideline protects against harm to bones.
