EWG's Tap Water Database — 2019 UPDATE




NOTE: Raymore purchases water from Kansas City which is required to test for molybdenum. Sample information shown below was taken by Kansas City.

Molybdenum is a metal that occurs naturally in soil, minerals and water. People who ingest large amounts can have increased levels of uric acid and gout-like symptoms.

State and national drinking water standards and health guidelines

EWG Health Guideline 40 ppb

The EWG Health Guideline of 40 ppb for molybdenum was defined by the Environmental Protection Agency as a benchmark for testing under the Unregulated Contaminant Monitoring Rule program. This health guideline protects against metabolic changes and excess formation of uric acid in the blood.
