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 starting July 1, 2018 and will remain in effect until permanent rules can be established later this year following a thorough, public rulemaking process.
As part of this rulemaking, water systems subject to these rules can send their samples to the Department of Environmental Quality’s laboratory in Hillsboro for analysis.

General questions about the entire process, please review the presentation or view the webinar. The webinar provides in-depth information concerning how to collect, package and ship your sample.
Sampling using the DEQ laboratory
The list of susceptible facilities is split into groups for the initial sampling schedule. Your facility’s group will remain the same as long as your facility remains on the basic every other week sampling requirement. Based on sample results, the frequency of your sampling may change.

Packing & Shipping
In order to maintain the integrity of your samples and the resulting data, samples must be sent to the laboratory in a cooler with sufficient ice packs to cool the sample. Please review the presentation above to see detailed instructions on packing.
