Abstract
In Rio de Janeiro’s metropolitan area comprise, over 8 million inhabitants receive drinking water from Company responsible for water and sewage, capted by the Guandu river’s water treatment station. Such water started to present unusual odour, taste and color in January 2020, as stated by the population itself. Results obtained through raw water microbiome metagenomic analysis inferred cyanobacteria presence, with Planktothricoides gender and Planktothricoides sp. SR001 being the most abundant gender and organism. Such do pose a risk to public health, as they are able to produce cyanotoxins that affect human health.
