Land contamination describes a general spectrum of site and soil conditions. It can include areas with elevated levels of naturally occurring substances, as well as specific sites that have been occupied by former industrial uses, which may have left a legacy of contamination from operational activities or from waste disposal.
Establishing contaminant sources.
Analysing the potential for unacceptable risks (what pathways and receptors could be present, what pollutant linkages could result and what could the effects be)
Predicting the magnitude and probability of the possible consequences (what degree of harm or pollution might result and to what receptors, and how likely is it) that may arise as a result of a hazard.
Deciding whether a risk is unacceptable
The exploitation of mineral resources, especially surface mining, causes numerous negative environmental externalities and socio-economic impacts, e.g., land use changes, ecosystem disturbances, watercourse relocation and a decrease in ground water level, changes in infrastructure networks, non-balanced industrial development, resettlement and changes in the economic and social structure of the local population.
Extractive industries in Romania have seen costs escalate mainly due to poor planning, low investments in technology innovation, inefficient operations and rising prices of water and energy. A new roadmap for collaborative, long-term sustainable metal extraction should be based on three pillars: shared purpose during and after the operation, flourishing ecosystems, with a reduced environmental footprint of every activity as the first step, and achievement of long-term sustainable prosperity for the communities. Terra Resources’ land management aims to sustainably extract value-bearing material in secondary material streams and stockpiles.
