The Civil Police reported that it is investigating whether Cedae employees or a third party committed a crime that resulted in changes in water characteristics in several neighborhoods of the Rio de Janeiro metropolitan region.
According to the agency, agents of the Delegate of Defense of the Delegated Services carried out demarches on Thursday (16) at the Guandu water treatment plant in Nova IguaÃ§u, where the presence of geosmina was detected last week.
It is this organic substance, according to the company, that is causing the taste and smell of soil in the water distributed by the station, which supplies more than 9 million of the 13 million residents of Greater Rio. It is produced when there is a sharp multiplication of bacteria in nutrient-rich aquatic environments, such as springs that receive untreated sewage.
Police stated that "the action is part of an investigation into the possible criminal liability of Cedae employees or third parties who may have contributed, by action or omission, to changes in water consumption conditions in recent days."
Case delegates say they have not ruled out any possibility so far, including sabotage. They have taken samples in the water for laboratory analysis and also plan to gather testimonials from company employees.
The operation comes two days after Governor Wilson Witzel (PSC) published in social networks that "the inconvenience that the population has been suffering is inadmissible" and affirmed that determined the determination of water quality and management processes of the company.
