    What to do if you are at a river, lake or the sea and suspect there is blue-green algae.

    If you are at a river, lake or the sea and suspect there is blue-green algae, follow these steps:

    Report it: Bloomin Algae App

    The Bloomin’ Algae App helps make reporting of blue-green algae easier and quicker, allowing environmental experts to respond faster and issue public warnings more efficiently. It enables users to submit a photo of an algae bloom on their mobile device, along with the location and activities taking place in the associated waters. Bloomin’ Algae App is free to download directly from:

    • Google Play
    • Apple App Store

    Find out more at: Bloomin’ Algae | UK Centre for Ecology & Hydrology (ceh.ac.uk)

    If you don’t have Bloomin Algae App – email photos to NIEA

    Report the bloom to the Northern Ireland Environment Agency. You can report any suspected blooms either by emailing the location and photographs to emergency-pollution@daera-ni.gov.uk.

    Follow any advice provided by the landowner/operator of the river, lake or beach.
