Guidelines for Canadian Drinking Water Quality: Guideline Technical Document - Chromium

From Health Canada

Overview

This guideline technical document provides the scientific information used to update the guideline for total chromium in drinking water. It reviews and assesses all identified health risks associated with chromium in drinking water, taking into consideration new studies and approaches as well as the availability of appropriate treatment technology. Based on this review, the drinking water guideline for total chromium is a maximum acceptable concentration (MAC) of 0.05 mg/L (50 µg/L). This information is made available to provide Canadian jurisdictions (provinces, territories and federal departments) with the scientific basis they need to establish or update their requirements for total chromium in drinking water.

Who this document is for
