Event description


The US Environmental Protection Agency’s (EPAs) Office of Water and Region 9, in collaboration with California's Surface Water Ambient Monitoring Program (SWAMP), will be conducting a Harmful Algal Blooms (HABs) Meeting, on April 25-27th, 2017. The Workshop will be held at the Southern California Coastal Water Research Project (SCCWRP) facility in Costa Mesa, CA.

The purpose of the HABs Meeting is to provide a collaborative and educational forum for state, tribal and local agencies, lake managers and water utilities, to engage on current, emerging, and advanced HAB issues. The Meeting is structured to provide a venue for participants to learn about approaches and partnerships occurring nationally, as well as opportunities to share regional, and local strategies and successes.

We have a full and excellent agenda! Starting at noon on April 25, the first session will focus on marine HABs, fisheries impacts, and forecasting systems for both marine and freshwater HABs. On April 26, the Meeting sessions will focus on freshwater HAB issues in recreational and drinking surface waters, including other states experiences addressing HABs, and strategies and tools for surface water monitoring and managing HABs. On April 27th, sessions will focus on HAB management and mitigation, and source water protection and drinking water managment. All sessions include time for discussion. Please plan to stay through to 5 pm on Thursday! A draft agenda is provided below.

The meeting is open to state, tribal, and federal partners, lake managers and water utilities. There is space for up to 120 people to attend in person and 250 attendees via webinar. Please select each of the days you plan to participate, and how you plan to participate (in-person or by webinar) when you click "Register" above.

There is a Pre-Meeting webinar on Wednesday, April 5th, offering an overview of freshwater HABs’ in drinking and recreational surface waters and information on HABs: causes, effects on human and animal populations, EPA regulatory guidelines, etc. Pleae register for the pre-meeting webinar at the separate Event Brite event: https://www.eventbrite.com/e/us-epa-region-9-hab-pre-meeting-webinar-tickets-31366518100 .

HABs Workshop Discussions Questions

States and tribes HABs Experience and Efforts

  • What are some of the ecological impacts you have experienced in your state, tribal area, county?

  • What public health guidance (recreational or drinking) is in use in your state, tribe, county? What has worked? What hasn’t?

  • How would you use the criteria values developed by EPA?

  • What are your biggest needs related to the development of guidance for the protection of public health and animals from exposure to cyanotoxins in recreational settings?

  • Are there water parameters associated with harmful algal blooms other than the cyanotoxins (microcystin and cylindrospermopsin) to consider for the development of recreational guidance values?

  • What are your biggest challenges and needs related to public communication messaging, reporting, and communicating risk around cyanotoxins?

  • What are your biggest challenges and needs related to coordinating communication and sharing information among agencies? What opportunities exist to make information sharing among internal agencies more effective?

  • What collaborations (e.g. voluntary programs, research by academia, other federal agencies like NOAA and CDC, Source Water Collaborative etc.) does your state, tribe, or county have?

  • What opportunities exist to further enhance public health protection through outreach?

Surface Water Blooms Monitoring

  • What toxins have been detected in your state, tribal area, or county?

  • What kinds of HAB monitoring, analysis, and prediction are you doing in your programs? What’s worked? What hasn’t?

  • Do you use indicators or surrogates (such as chlorophyll a levels) with an established relationship to:

    • surface water body algal toxins for predictions, trends, and assessments? What indicators?

    • public water system algal toxins for predictions, trends, and assessments? What indicators?

  • Are CWA and SDWA monitoring programs coordinating to address both recreational and drinking water uses? For example, Is HAB monitoring included in your state or tribal monitoring strategy? If not, do you have plans to include it?

  • Any innovative approaches that are specific to your programs?

  • What are the biggest information/data gaps in your monitoring and assessment programs?

  • What are your biggest needs for improving your monitoring, analyzing, and predicting of HABs?

  • What funding opportunities for HAB monitoring are available?

  • Are any states, tribes, counties using something other than real-time cyanobacterial cell or toxin monitoring to inform drinking water advisories or advisories/warnings/danger postings for recreational protection?

  • Do some states, tribes, counties post advisories proactively based on past data?

  • Have states, tribes, counties incorporated HAB monitoring into fish consumption advisories? If so, how?

Management and Mitigation and Source Water Protection

  • What treatment and analytical techniques have you used/are you using in your programs? Did/do they work? Why or why not?

  • What are your biggest needs concerning drinking water treatment and analytical methods?

  • What recommendations do you have for small public water systems (for example, on inland lakes) that may not have the capacity to add treatment, monitor, or receive CWA funding?

  • What are examples of management and protection strategies that you are using in your programs for nutrients and HAB reduction in surface waters and/or source waters (sources of drinking water)? What’s worked? What hasn’t?

  • How are you working with stakeholders to reduce nutrient pollution to prevent HABs (e.g., public outreach for the reduction of fertilizer use)? What is/isn’t working? Any recommendations?

  • Are your programs coordinating across SDWA and CWA programs to address protection of source waters from HABs? For example, have the state nutrient reduction strategies helped to make connections between the CWA and SDWA programs? Are there lessons from the development of state nutrient reduction strategies that could help states develop and enhance HAB strategies?

  • What are your biggest obstacles to implementing measures to reduce nutrients and HAB formation? Any of these specific to source water protection?

  • What do you think the biggest needs are for nutrient reduction and HAB formation in your state’s watersheds and waterbodies?

  • Do drinking water utilities have the opportunity to work with upstream partners to address the sources of the problem, or are they the only ones held accountable?

  • What recommendations do you have for small public water systems (for example, on inland lakes) that may not have the capacity to add treatment, monitor, or receive CWA funding?

Days 1 and 2 wrap up sessions

  • Is there anything in particular from the presentations and discussions that you think will be applicable to your programs? What and how?

  • What follow-up would be helpful for Region 9 to undertake?

  • Would additional workshops, webinars, or conference calls on particular topics be helpful to continue the conversations started here or address additional issues?
