Guidelines for Canadian Drinking Water Quality: Guideline Technical Document – Bromate

Overview

This guideline technical document provides the scientific information used to update the guideline for bromate in drinking water. It reviews and assesses all identified health risks associated with bromate in drinking water, taking into consideration new studies and approaches as well as the availability of appropriate treatment technology. Based on this review, the guideline for bromate in drinking water is a maximum acceptable concentration of 0.01 mg/L (10 µg/L), based on a locational running annual average of a minimum of quarterly samples. 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 bromate in drinking water.
