What is blue-green algae and will there be any in the water at SwimSnowdonia?
Blue-green algae are minute plants which occur naturally in lakes, ponds, reservoirs, rivers and the sea. When it blooms, it can form a scum and produce toxic substances. These commonly occur during periods of prolonged hot weather in calm waters – such as the water’s edge or shoreline. Given this, blue-green algae is not a regular occurrence, however we will be monitoring the water quality in the lead up to the event and taking steps to ensure that blue-green algae does not form in the area where SwimSnowdonia is taking place. Despite this, for your safety we would advise that you do not drink the water and try to ingest as little water as possible during the swim.
