Cyanotoxins

Cyanotoxins and Drinking Water. Salem workers distribute water to residents from one of the Consortium member's water distribution trailers.

Water providers actively monitor the region’s watersheds to check for the presence and levels of blue-green algae, the type of algae associated with harmful algal blooms that can produce cyanotoxins. Water sources and water treatment methods are different throughout the region and the state, so contact your water provider to learn more. To learn more about regional water sources click here.

Helping neighbors: Consortium members sent five emergency water distribution trailers to the Salem area to provide drinking water to residents during the summer of 2018 when cyanotoxins were detected there. Thank you to the Cities of Beaverton and Gresham, Clackamas River Water, the Portland Water Bureau, and Tualatin Valley Water District for helping out.

What you can do: Be prepared. Add water to your emergency kit – 1 gallon per person per day for 14 days is recommended. See how to safely store water in your own container and how to access water from your water heater. Use the Consortium’s Drinking Water Advisory tool to see if you are in an affected area when a drinking water advisory is issued by any of the Consortium’s water provider members.
