Members of the public should be aware of the dangers posed by poisonous plants and algae growing in the environment, but especially along riverbanks, in sea water / beaches and in wet grassland or edges of lakes. In warmer weather conditions, there can be a rapid increase in the growth of algal blooms.
If Council receives notification from NIEA confirming the presence of potentially toxic algal blooms, we will erect advisory signs to warn the public as soon as possible.
What is blue-green algae?
Blue-green algae is not actually an alga but rather a type of bacteria called cyanobacteria. Cyanobacteria naturally inhabit our freshwater, coastal and marine waters and, like plants, require sunlight, nutrients and carbon dioxide to grow and reproduce.
Algal blooms can occur throughout the year, but they are most common from May through to September when suitable weather conditions combine with a ready supply of nutrients particularly phosphorus.
To make a report:
If you suspect you have sighted this alga you should avoid all contact with the affected waters, and ensure that pets also do not make contact with the affected water, dogs should be kept on leads.

All reports of sightings of blue-green algae need to be reported to NIEA by either ringing 0800 80 70 60 or logging on the Bloomin’ Algae App or by emailing emergency-pollution@daera-ni.gov.uk.
Advice if exposed to blue green algae:
If you are concerned about exposure to blue-green algae, you should shower immediately and seek medical advice if feeling unwell. Similarly, if pets are exposed, they should be showered immediately, and their vet contacted promptly.
Anyone with concerns about blue-green algae affecting their public drinking water supply should contact Waterline on 03457 00 44 88 or on waterline@niwater.com.
