Blue-Green Algae - News Update

As algal blooms are often associated with warmer conditions coupled with longer day light hours, the likelihood of blooms developing is expected to increase. As we move into the summer months the public are advised to remain vigilant and to follow signage erected by local authorities along our rivers, lakes and shorelines.

Blue-Green Algae - Confirmed Locations

DAERA has worked with the Northern Ireland Environment Agency (NIEA), Agri-Food & Biosciences Institute (AFBI), NI Water, Food Standard Authority, and the Public Health Agency on the production of an Inter-Agency Blue- Green Algae Monitoring Protocol. The protocol describes the roles and responsibilities of both organisations and individuals, as well as how we monitor different types of waterways, depending on usage. It details the DAERA Response Protocol for surveillance and monitoring blue-green algae and outlines the Bathing Water Monitoring in place for 2024.

Blue-Green algae, or cyanobacteria as they are correctly called, have the potential to release toxins and the public is reminded that blue-green algae can be harmful to humans and is highly toxic to animals.

NIEA will continue to investigate reports of algal blooms submitted through the incident hotline or Bloomin’ Algae App to confirm if blue green algae are present. Notifications of confirmed blooms are then sent to the person who reported the bloom and the relevant local authority and other stakeholders.

Members of the public can report suspected blue green algal blooms in several ways - via the Bloomin Algae App which can be downloaded at: UK Centre for Ecology & Hydrology | ceh.ac.uk or e-mail emergency-pollution@daera-ni.gov.uk or phone 0800 80 70 60.
