Our priority is to carry out actions aimed at recovering the area impacted by the collapse of Dam B1, in Brumadinho.

It is our duty and our priority to carry out actions aimed at the environmental recovery of the entire area affected by the collapse of Dam B1, in Brumadinho. 

To this end, we remain committed to carrying out actions to monitor local biodiversity, such as water, soil and animals, in addition to carrying out activities aimed at the revegetation of affected areas. 

We are also committed to ensuring quality water for populations that depended on abstraction from the Paraopeba River.

Paraopeba river water quality 

The restoration of the Paraopeba River is one of the main commitments of our environmental reparation work.

Since the reparation of Dam B1, in Brumadinho, in addition to the monthly monitoring carried out by the Minas Gerais Water Management Institute (Igam), we have monitored the quality of the waters of the Paraopeba River and its tributaries. The data obtained from the monitoring works is periodically delivered to inspection bodies and to the Public Presecution Office of Minas Gerais.

What are the results obtained so far? 

  • Since May 2019, the Paraopeba River has not received tailings loading; 
     
  • The tailings did not reach the São Francisco River. The impacts on water quality were identified up to the limit with the Retiro Baixo Hydroelectric Power Plant, in Pompéu (MG);
     
  • No impacts were detected on the waters of the Três Marias Hydroelectric Power Plant reservoir, as demonstrated in studies by environmental agencies;
     
  • The turbidity levels and the total metals, Manganese, Iron and Aluminum, are progressively reducing during the dry period, and statistical trend tests prove an improvement in the water quality of the affected regions.

Water supply

After the collapse of Dam B1, in Brumadinho, the use of water from the Paraopeba River was interrupted and Vale assumed a commitment, together with the competent public bodies, to ensure the water supply of all affected municipalities.

For this, we carry out corrective actions (aimed at animal consumption, agricultural irrigation and human consumption) and preventive actions (to ensure water security and adequacy in public supply).

So far, Vale has provided a flow rate of: 

204,060,040

L/day for public supply 

Volume of mineral water supplied to communities 

19,306,838

million liters 

Volume of water made available by drilled wells 

2,384,773,800

of liters 

In a total of: 

3,586,476,649

Liters

Discover the actions being carried out 

The action seeks to ensure quality water for the population living in the areas between Brumadinho and the Três Marias reservoir.
Among the initiatives for preventive actions, there is the installation of a containment barrier that surrounds the Bela Fama water withdrawal, in Nova Lima. The barrier is about 3 meters high and 300 meters long and its works were completed in December 2019. 
We are developing projects to ensure that the water demand of RMBH corresponds to 15,000 l/s. 
The Commitment Agreement also includes the preparation of the project for a treated water pipeline with approximately 30 km in length. It will connect two reservoirs (R10-R13), increasing the transfer between the Paraopeba and Velhas river water systems.  
We are also developing studies and projects for the implementation of a new water withdrawal in the Velhas river, in the Ponte de Arame region.  
The scope also includes water withdrawal in Ribeirão da Prata, which includes run-of-river water withdrawal and a 9 km pipeline to the ETA Bela Fama.

The data obtained from the monitoring works is periodically delivered to inspection agencies and to the Public Presecution Office of Minas Gerais.
