The municipality of Pará de Minas has created a crisis committee to badess the consequences of ore residues in the Paraopeba River. The city was the first to have supplies affected by mud.
Hands on the logs. Since she learned about the possible arrival of residues from the Brumadinho Dam, Ms. Cléia decided to protect herself.
"I closed the records of fear of mud contamination, contamination of the water from my box," says Cléia Cândido da Silva, housewife.
But the water that arrives in the house of about 100,000 inhabitants of Pará de Minas does not come from Paraopeba. This Friday (1st), the city is fed by two creeks and 16 artesian wells.
Three days ago, Vale is working on the installation of containment barriers to prevent sediment from reaching the Paraopeba River. The town of Pará de Minas is about 90 kilometers from the point where the mud has reached the river.
According to Vale's forecast, technicians would install three lines of floating gates. Two of them will be located before the point where the Pará de Minas supply company will capture the waters of the Paraopeba River. The third, already ready, prevents residues from reaching the piping and collection pumps.
The barriers have metal chains on the sides and sinkers on the bottom to keep the membranes stretched up to the bottom of the river. The objective is that this type of filter prevents solid waste, such as clay and organic matter, from creating turbidity and altering the transparency of water, along of the river.
Technicians will periodically clean the accumulated residues in the membranes. The barriers will also prevent residues from reaching the Retiro Baixo hydropower plant in Pompeii. And the factory of Três Marias in the São Francisco Basin.
The installation is expected to end early next week.
The company in charge of supplying Pará de Minas is studying the possibility of asking neighboring municipalities for badistance if the water of the Paraopeba river is unfit for consumption for a prolonged period. Itaúna, for example – at about 30 km – captures water from other sources and could help with kite cars.
The company also does not exclude a rotation of supply:
"We are talking about this possibility, we will communicate it preemptively to the city, yes, in order to maximize the regularity of the arrival of this water for the people, "says Thiago Contage, superintendent of the concessionaire Águas de Pará de Minas.
The order is to save and Dona Eunice, even in the factories, uses the water consciously:
"A difficult time.This water contamination we do not know what It's going to save even more money than we are now, "says housewife Eunice dos Santos.
