Hosted by EPA's Office of Research and Development, Office of Water, and regional offices, this free webinar series is focused on communicating the latest, cutting-edge research related to nutrients and the priority impacts of nutrient pollution: harmful algal blooms (HABs) and hypoxia.

Topics will include regional priorities; regulatory updates; and cutting-edge EPA research related to monitoring and forecasting, prevention, control, and response.

Webinars are typically held bimonthly from 2 to 3 p.m. ET on the last Wednesday of the month. Additional information and registration will be posted closer to the scheduled date and as they become available.
