BRASÍLIA – A
lama
iron ore residues from the
Vale
who broke into
Brumadinho
(MG) will arrive at the Três Marias hydroelectric plant,
São Francisco River,
from February 15th. The forecast concerns researchers from the Brazilian Geological Survey (CPRM) and was revealed in the first special Rio Paraopeba surveillance bulletin produced by the agency.
The Paraopeba River is one of the major tributaries of the São Francisco River. Controlled by Cemig, the factory of Três Marias is the first installed along the São Francisco River. Calculations by government officials indicate that the mud will arrive at the plant between the 15th and 20th of next month.
Before, the mud should arrive in the region of São José da Varginha in the night of this Tuesday. Then the wave of residues will pbad through the Retiro Baixo hydropower plant between February 5th and 10th. According to government forecasts, the dam will "depreciate" much of the tailings sludge dumped into the river.
According to the government, the mud wave is crossing the site at a speed of one kilometer per hour.
According to the CPRM, two monitoring bulletins will be issued daily with the forecast of the arrival of the beginning of troubled waters at points of interest along the Paraopeba. The methodology used uses observed field data and watershed characteristics.
The CPMR bulletin is the first government document to declare that the mud of the Vale dam will reach the São Francisco River. Earlier, also Monday, the Mining Secretary of the Ministry of Mines and Energy, Alexander Vidigal, denied that the residues join Três Marias.
On Sunday, Regional Development Minister Gustavo Canuto said the government was working with a low probability that the mud wave would contaminate San Francisco.
The number of deaths due to dam failure
rose to 60 on Monday.
According to Lt. Col. Flávio Godinho, one of the coordinators of the rescue operation, 19 bodies were identified. According to the latest published bulletin, the number of missing persons reaches 292.
