Renova continued to carry out training on how to use the MP5. In November, technicians from the National Water Agency, ICMBio and Ibama received training in Brasilia (DF).

As requested per Technical Note by the Technical Monitoring Group of the Qualitative Quantitative Systematic Monitoring Program (PMQQS), in November, Renova published the first two editions of the Weekly Rainy Season Water Quality Report on its website, featuring the compiled data of the installed multiparametric probes. In compliance with the policy for transparency and accessibility of information, the information will be published until the end of the rainy season in March 2018.

A descriptive report was sent to the CTSHQA containing the alterations made to the automatic stations and the necessary photographic records, in order to prove compliance with the alterations requested in Technical Note No. 12 of resolution 99 of the Inter-Federative Committee (CIF).

The laboratory reports of the collections of the Qualitative Quantitative Systematic Monitoring Program (PMQQS) were made available in the MP5 (database). In order to use the MP5, training was provided to the environmental and water resources technicians involved in the analysis and evaluation of the PMQQS in Belo Horizonte (MG) and Vitoria (ES).

The nonconformities detected for the electrical conductivity parameter in the automatic monitoring station in Cachoeira Escura, which triggered the alert level defined in the PMQQS, were evaluated. This activation of the alert level was duly informed to the CTSHQA together with a report of the results of the extra collections.

In addition, the Quali-Quantitative Monitoring Plan for the Waters of the Doce River and its Tributaries was initiated in function of the interventions in October and delivery of the schedule of the field collections.

The schedule of manual collections for the months September to December of 2017 was registered and submitted for evaluation by the members of the Technical Board for Water Security and Water Quality (CTSHQA). The maintenance procedures of the probe were also adjusted, as per established in the Qualitative Quantitative Systematic Monitoring Program (PMQQS).

The lightning arresters installed in the stations were removed and the turbidity sensor at the Rio do Carmo station RCA-01, in Acaiaca (MG), was repositioned outside the backwater area.

In addition, operations were completed of 4 automatic stations as part of the monitoring of the areas where there are interventions (PMQQVAI) of the Renova Foundation.

The activities of manual water and sediments sampling have begun in 92 monitoring points. Conventional parameters such as ions, nutrients, total and dissolved metals and biological indicators will be evaluated.

The proposed monitoring network for the Doce River basin, estuarine and coastal zone is defined in representative points to monitor the evolution of the water and sediment quality, to identify trends and to investigate and assess. The Quali-Quantitative Systematic Monitoring Program (PMQQS) will be in place for 10 years, period provided in the Transaction and Conduct Adjustment Term (TTAC) for the execution of the compensatory and environmental recovery actions of the Doce River basin.

The report that presents the results of the investigation of water quality, colloids and sediments in the Carmo River (MG) and the schedule of the manual collections in August was filed and submitted for evaluation by the members of the Technical Board.

With the completion of the installation of the automatic monitoring stations, the Renova Foundation filed a letter of compliance with Clause 177 of the Transaction and Conduct Adjustment Term (TTAC) with the Inter-Federative Committee (CIF) and in the Technical Board of Water Safety and Water Quality (CTSHQA).

Inspection of the automatic monitoring stations, in order to verify the conformity of the equipment and its performance according to the established requirements. In the inspection action participated: professionals of the National Water Agency (ANA); of the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA); of the Chico Mendes Institute for Biodiversity Conservation (ICMBio); State Water Management Institute of Minas Gerais (IGAM); The Secretary of State for Environment and Water Resources (Seama); the State Institute of the Environment of Espirito Santo (IEMA); the State Agency for Water Resources (AGERH-ES) and members of the Doce River Basin Committee (CBH-Doce).

All 22 stations will indicate the volume of rainfall and the water level of the river where they are installed, of which 13 are equipped with instruments that analyze the turbidity of the water in real time. Of these 13 stations, 8 will analyze turbidity and also parameters such as pH, electrical conductivity and oxygen concentration dissolved in water. In addition, there will be online transmission of the results to form an information and alert network. This information may support the preventive planning of the main public water supply systems.

Completion of the contracting process of the laboratory that will perform the Systematic Quali-Quantitative Monitoring Plan (PMQQS). The ALS Corplab laboratory will be responsible for the collection and analysis of water and sediment samples in the Doce river basin.

Six automatic monitoring stations were installed which will contribute to the acquisition of data on water quality, river flow, rainfall, among others.

Of the 22 stations already installed, 13 will be equipped with instruments that analyze the turbidity of water in real time. Of these 13 stations, 8 will analyze turbidity and also parameters such as pH, electrical conductivity and oxygen concentration dissolved in water.

In May 2017, the installation of the 22 civic bases of the automatic water quality monitoring stations on the banks of the Gualaxo do Norte, Carmo and Doce rivers was completed in the stretch between the S4 dam, located in Bento Rodrigues (MG), and the mouth of the Doce River (ES). All stations will indicate the volume of rainfall and the river water level of the locations where it will be installed. Of the 22 stations, 13 will be equipped with instruments that analyze the turbidity of water in real time. Of these 13 stations, 8 will analyze, besides turbidity, parameters such as pH, electrical conductivity and oxygen concentration dissolved in water.

In April 2017, the authorizations of the owners of the land where the 22 automatic monitoring stations will be installed, as requested by the Interfederative Committee (CIF), were obtained. These areas are located on the banks of the Gualaxo do Norte, Carmo and Doce rivers, between the S4 dam, located in Bento Rodrigues (MG), and the mouth of Doce River (ES). In addition, Renova will install five more stations in tributaries of the Gualaxo do Norte and Carmo rivers, impacted by the collapse, and two more mobile stations to support the dredging process at the hydroelectric power plant Risoleta Neves.

In March, three automatic monitoring stations were installed in the municipalities of Santa Cruz do Escalvado, Rio Doce and São Domingos do Prata, in Minas Gerais. Furthermore, the document that specifies the Quali-Quantitative Systematic Monitoring Program (PMQQS) of water and sediment of the Rio Doce Basin was completed.

Last month, water samples were collected for the analysis of colloids and suspended particulate matter. The following were filed: the review of the Permanent Quanti-Qualitative Monitoring Plan, the updated reports related to the water quality and sediments in the basin of the Doce River and the coastal zone and diagnosis of the water quality in the basin of the Doce River and the coastal zone previous to the collapse of the Fundão dam. The installation of the automatic monitoring stations has also begun, with the completion of civil construction works. As a result of the tailings containment and recovery activities, the turbidity index has shown a reduction over the entire area affected by the dam collapse. In February, the turbidity levels in the Carmo River for the first time reached levels below 100 NTU.

Last month, water was collected for the analysis of particulate matter analysis and the frequency of Doce river water monitoring has changed, from weekly to biweekly. Moreover, the hiring strategy was defined for both companies, which will be working on a parallel implementation of the automatic monitoring stations. The installation of the stations was authorized by the owners of 14 plots, of a total of 21. The process of manufacturing the automatic monitoring stations in Candonga has also started, as well as the civil construction works. The delivery of the stations in Brazil is scheduled for February.

This month the Renova Foundation received the final version from the National Water Agency (ANA) of the proposal regarding the minimum content for the Quali-Quantitative Doce River Water and Sediments Monitoring Program. Water samples were taken for analysis of colloids, in addition to the adjustment that was made in the frequency of monitoring the Doce River water, from fortnightly to weekly, due to the rainy season.

Last month, the monitoring frequency of the Doce River water was changed from fortnightly to weekly, and the total aluminum monitoring in the Water Treatment Plants (ETAs) of Governador Valadares (MG) was completed. The Renova Foundation received the final version of the National Water Agency (ANA) of the proposal regarding the minimum content for the Quali-Quantitative Doce River Water and Sediments Monitoring Program. On November 21 and 22, a meeting was held with representatives of the Brazilian Institute of Environment and Natural Renewable Resources (Ibama) to discuss the monitoring results of the Doce River and the Coastal Zone.

A simulated oil spill was carried out at the docks in Santa Cruz and Aracruz, Espírito Santo, where the boats used for the monitoring are allocated. In addition, in the same period, the mapping of irrigation points, by means of remote sensing, was completed. The bathing reports (evaluation of the possibility of bathing and sports activities in waters), in Regence (ES), presented coliform values above the limit. Study will be conducted to map the possible pollution sources that justify such results.

The daily aluminum quantity monitoring in the Water Treatment Plants (WTP) has started in Governador Valadares (MG), performed simultaneously in three laboratories, as well as the identification studies of irrigation areas on the affected route. Moreover, the Renova Foundation met with representatives of the National Indian Foundation (Funai) to present a technical report of the Sahy, Guaxindiba and Piraque-Açu river water quality, as part of the TTAC with the indigenous tribes of Aracruz.
