Temporary Rules for Cyanotoxin Monitoring at Public Drinking Water Systems
Effective July 1, 2018
Oregon Health Authority has developed temporary rules that will require drinking water systems in the state using certain surface water sources, such as those prone to harmful algae blooms, to routinely test for cyanotoxins that these blooms produce, and notify the public about the test results.
These rules are effective July 1, 2018 and will remain in effect until permanent rules can be established later this year following a thorough, public rulemaking process.
In the meantime, OHA is encouraging water systems that serve surface water that has had algae issues in the past to voluntarily test for cyanotoxins and notify the public about the results.
In the coming weeks and months, OHA will post updates on this page to inform the public about the rulemaking process, including meeting notices for the rulemaking process, draft of rules and ways to make public comment. For more information, contact Drinking Water Services.
