    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.

    Oregon Revised Statue (ORS) Oregon Drinking Water Quality Act

    Enacted in 1981, the statute (periodically amended) includes Oregon Revised Statute (ORS) 448.119 to 448.285; 454.235; and 454.255. The purpose of the above act is (in part) to:
    • Ensure that all Oregonians have safe drinking water;
    • Provide a simple and effective regulatory program for drinking water systems; and
    • Provide a means to improve inadequate drinking water systems.

    Current Oregon Administrative Rules (OARs) for Public Water Systems

    ORS 448.131 authorizes Drinking Water Services (DWS) to adopt administrative rules to ensure safe drinking water. OAR Chapter 333 Division 061 is reserved for regulations regarding public water systems and was last amended on January 10, 2018.

    Specific portions of the rules are also available as PDF files below, ordered by section number (some of the files include more than one section of the rules):

    OARs for Cross Connection and Backflow Prevention

    The cross connection and backflow prevention rules serve to protect public water supplies from backflow hazards. They are provided below as PDF files.

    OARs for Water System Operator Certification

    The purpose of operator certification is to protect public health and public water systems in Oregon. DWS accomplishes this by reviewing the experience, education and credentials of persons responsible for the production, treatment and distribution of public drinking water and determining their compliance with an established standard of proficiency. The rules include application guidelines, general operator criteria and grade requirements; operator system classifications and fees are also covered. They are provided below as PDF files; some of the files include more than one section of the rules, in which case the content is ordered by section number.

    OARs for Domestic Well Testing for Real Estate Transactions

    Amended in 2009, ORS 448.271 requires property owners, when selling Oregon real estate that includes a domestic well, to test the water for arsenic, nitrate and total coliform bacteria. Domestic wells are those used for drinking and other household purposes. Test results must be reported within 90 days to the real estate buyer and DWS after the seller receives the test results. Rules are downloadable as PDFs below. Get more information about domestic well testing for real estate transactions.
