Overview
This guideline technical document provides the scientific information used to update the guideline for cyanobacterial toxins in drinking water. It reviews and assesses all identified health risks associated with cyanobacterial toxins 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 total microcystins in drinking water is a maximum acceptable concentration of 0.0015 mg/L (1.5 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 cyanobacterial toxins in drinking water.
