Join Our Listserv

The HABS program has created a listserv to share information with partners, stakeholders and interested public. When a health advisory is issued, an email is sent to subscribers that includes the news release and water sample results (algae species and cell counts). Emails are also sent when an advisory is lifted. Other timely information may be periodically shared as well. To join the list, email us at Hab.health@state.or.us.
