    Context:

    The intelligent use of water is a priority in Suzano’s investments, as we understand that this is an important natural resource for the balance of our ecosystems and the continuity of our business. In this sense, we perform periodic measurements of qualitative and quantitative parameters of the main watersheds in which we operate.

    Additional information:

    There are specific parameters to be monitored in each watershed and per state, resulting from compliance with the requirements established in the permits of each state.

    In São Paulo, the parameters monitored in the 6 watersheds are: nitrate, phosphorus, potassium, turbidity, calcium, pH, magnesium, color, suspended solids, temperature. and conductivity.

    In Mato Grosso do Sul, six points are monitored on the farms: Matão, Duas Marias, Granada, Vista Alegre, São Marcos, and Antares. The qualitative parameters analyzed are: Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), turbidity, nitrogen, phosphorus, calcium, magnesium, potassium, dissolved oxygen, pH, temperature, and suspended solids. The quantitative parameters are: flow measurement through data collection with Datalogger equipment and flow probes for subsequent calculation of flow rates.

    In the states of Bahia, Minas Gerais, and Espírito Santo, laboratory and on-site analyses are performed. The monitored parameters are: pH, temperature, dissolved oxygen, thermotolerant coliform, BOD, nitrogen, phosphorus, turbidity, total residue, sulfuramide, glyphosate, conductivity, flow, BOD, aluminum, boron, cadmium, lead, cyanide, copper, chromium, iron, fluoride, manganese, nitrate, nitrite, sulfides, zinc, Vibrio Fischeri, and pesticides.

    For groundwater in Bahia, the following parameters are also monitored: COD, dichlorobenzenes, dichloroethane, dichloroethane, glyphosate, dichloroethane, dichloroethane, dichlorobenzene, and dichloroethene.

    In Maranhão, the following parameters are evaluated bimonthly: turbidity, pH, conductivity, temperature, nitrogen, phosphorus, suspended solids, potassium, oxygen, magnesium, calcium, BOD, COD, color, dissolved solids, total solids, and flow.
