Lake water in Britain may cause dementia.

Colonies of toxic algae found in freshwater lakes could pose a threat to drinking water.

According to the latest study conducted by the experts from the University of Nottingham and McGill University of Canada, poisonous algae found in Britain’s lakes may contain bacteria which causes Alzeimer’s Parkinson’s and motor neurone disease.

Scientists examined more than 100 lakes across Europe and North America, and have recorded a significant increase in poisonous algae in freshwater lakes since the 1880s. These algae contain toxins that can damage the nervous system and the liver, and is linked to neurodegenerative conditions.

A simple solution to the problem is to have a drinking water filter in your house to improve the quality of your water.
