Environmental investigation of liabilities

Context

Development of the Preliminary Assessment Report and the Confirmatory Investigation Plan in areas of paralyzed mines.

Methodology performed

Levantamento de dados primários e secundários, incluindo, por exemplo, levantamento aerofotogramétrico temporal, de modo a caracterizar as alterações do uso e ocupação do solo na área alvo e no seu entorno; entrevistas e inspeções em campo. O Plano de Investigação Confirmatória é elaborado em função da disponibilidade, da qualidade dos dados e das informações obtidas, os quais  fundamentarão o Modelo Conceitual Inicial da Área – MCA, com seus diferentes níveis de incertezas.

Results

Through the collection of data and developed studies, the aim is to find evidence, clues or facts that allow suspecting the existence of contamination in the areas, verifying the need or not to continue the investigation (execution of the Confirmatory Investigation Plan).
