Blue-green algae has been found at four locations in Eindhoven, according to a survey by the Dommel Water Authority. It concerns the Oude Gracht, the Cassandraplein, lakes in Meerhoven and the Henri Dunant Park.

Contact with water contaminated with blue-green algae can cause health problems such as headaches, skin irritation and nausea. Pets and animals can also develop health problems if they swim or drink from water with blue-green algae.

The Water Authority advises both people and animals to avoid water with blue-green algae. In addition to blue-green algae, botulism may also have been found in two places in Eindhoven. These are Center lake West in Meerhoven and the Drainage Canal.
