1663 Figure 1 – Conceptual Site Model for the closure stage Figure 2 – Conceptual Site Model for post-mining land use 2.2 Contamination characterization This phase involves the consolidation of site-specific environmental data and the evaluation of their representativeness for the environmental media under assessment. The objective is to ensure that available data is sufficient to estimate exposure at relevant points of contact. Where data gaps are identified, complementary sampling programs are defined. Validated results are organized by environmental matrix, exposure pathway (ingestion, inhalation, and dermal contact), and receptor type, allowing transparent identification of contaminants of concern.
